Where can you rent a boat for cruising the San Juan Islands

     Renting a yacht is a very viable option.  

We have rented and recommend you consider renting too, why? see below.

Ahoy savings

Lets see why you would rent:

• you may not have a boat
• your boat is not trailerable from Kansas or Kentucky
• your drift boat is trailer ready but it sucks for camping
• renting is a chance to try something different, like a bigger boat
• because it doesn't make sense to own a boat and only use it once a year  (unless your afflicted with  boaters syndrome where you may own many boats you don't use)
• switch from power to sail or sail to power
• because you can't afford to throw your money into a hole in the sea
• to find out if sailing/boating is ok with your family pet, wife, kids, self

Now let's dispel some myths that are true some of the time: 

• renting is cheaper than owning  - yes, with some exceptions
• you must have a competency certificate to rent - absolutely not but you must have your state issued boaters card anytime you operate any boat.
• is it safe to do this as a novice that has good sense - yes
• is it safe to do this as a novice if some relatives that know you well caution you not to - no!
  (listen to friends and relatives) they know if your an idiot and a menace to all around you - just kidding but bring a level headed 1st mate to help with tough choices like - red on the right! or red on left! or red on bottom?
• can a power boater but non sailor rent a sailboat and have a great vacation and learn to sail - absolutely, but the competency thing may come up for bigger boats so bring a sailor friend
• can you rent power and sailboats in the San Juans - yes
• how much will it cost - small boat $100 - $200 a day (power or Sail)
• how much for a bigger rig - $500 and up, up and away
• should I get the added insurance offered - probably talk to your agent
• how many days should I plan for  -  5 / 7 days is very nice but two weeks would be awesome
• only go in mid June to mid Sept. - yes, unless you can save big and don't mind a little snotty weather tossed your way, then go anytime but be prepared for unpleasant things.

The 38 foot boat we rented for about $3000 a week, slept eight and handled bad weather very nice, but as you can see, the weather was not bad. Rental boats should be fully equipped with safety gear and navigation supplies for your travel area but don't assume anything. The boat above came with a 12 foot sailing tender, economical single diesel, thruster, chart plotter and radar.

Rent boats in Anacortes or Bellingham, but do some online research and find private rentals too.

San Juan area campgrounds with boat ramps

      If camping is your primary activity and your boat is for day use such as exploring, fishing and crabbing, 

you will find these parks of interest.

On the mainland:

Washington Park in Anacortes - located one mile past the ferry landing.

Washington Park boat ramp in Anacortes

Excerpt from their website: In the campground there are 68 campsites, 46 have water and electrical hook-ups. These rent for $27 a night. There are 22 non-utility sites that rent for $21 per night. There are 25 sites available on a first-come, first-served basis. Please note that reservations must be made 14 days in advance. A sewer dump station is located near the park exit. Camping check-in and check-out time is 1 p.m. The campground is open year round. Please note: Maximum stay limit is 14 days. Visit the reservation website.  click here >> Washington Park The boat launch at Washington Park was developed and is maintained for the specific use of recreational boaters. Boat launch parking is $9/day and boaters may stay a maximum of 14 days. The two lane launch ramp is suitable for all trailer-able boats, power or sail.  You may not overnight at dock, but may anchor nearby. Ramp is a short walk to campground.

Deception Pass State Park - roughly ten miles south of Anacortes.  It is important to note some of the differences between Washington Park and Deception Pass Park.  While Deception Pass camp sites exceed three hundred in three different campgrounds, none are walking distance to the four lane boat ramp at Cornet Bay. However the modern well designed boat ramp claims to have two thousand feet of side tie moorage and overnight at the dock for up to three nights is allowed. Anchoring close by is simple and free. The ramp parking lot is massive and long term is allowed for a fee.

Four lane all tide - Cornet Bay ramp at Deception Pass Park is open 24/7

Lastly: Those putting in at Washington Park will be much closer to the inner island area after simply crossing Rosario Strait (four miles), but those putting in at Cornet Bay will have to deal with the pass and a longer run up Rosario or an even longer run through Swinomish Channel. These are not insignificant differences and should be well considered according to your overall plan before making your decision.

In the Islands:

Odlin County Park on Lopez Island

Odlin park has thirty one campsites and reservations are a good idea.  The boat ramp is sub parr at best and is not suitable for anything but a small skiff and a four wheel drive. There is no ramp dock and best used at high tide only. The ramp is a short walk to the campground.

San Juan County Park on San Juan Island

San Juan park is very similar to Odlin park with twenty six sites, they also take reservations.
The boat ramp is also sub parr and should only be considered for skiffs being hauled with four wheel drives, again the ramp is in the park and there is no float.

Moran State Park on Orcas Island is a State Park as is Deception Pass. 

They boast over one hundred campsites, some suitable for RV's.  Moran park is not ocean front and does not have a salt water ramp, however it is only five miles to the county boat ramp at Obstruction Pass.

  A private park alternative on Orcas Island is West Beach Resort in Eastsound

 They have camping, docks, fuel, deli store and a boat ramp, suitable for skiffs and four wheel drives.

San Juan Island: 

 If you take your skiff to San Juan Island and stay at a private residence, rental or hotel you can put the boat in at Jackson Beach day use park. The ramp is well designed, has parking and a dock. Jackson Beach is about two miles from Friday Harbor.

Ferries and trailers:

        Don't forget to check the ferry schedules and fares, hauling trailers on the ferry can get expensive and frustrating - very few cruisers do it!

My recommendation for mainland camping is that you get a reservation and camp at Washington Park, 
the run time to Friday Harbor is under an hour, the entire San Juan area will be at your door.

First Timers Guide to the San Juan's

Matia Island

This post is written to help new cruisers headed to the San Juan's needing the same simple answers we needed.

From time to time I refresh my thinking and remember our first visit nearly thirty years ago. Specifically what a pain it was not knowing the simplest answers to questions many of us take for granted today. 

     I define the San Juan cruising area not by county or even country, but rather by places we want to visit and spend some time. But that also means, places we have the capability to get to without too much effort or time.  So that being stated, I think of Port Townsend and Deception Pass Park (Cornet Bay), and Swinomish Channel as our loosely defined southern boundary.  I think of Vancouver BC and Nanaimo as our northern most point, and everything in between Vancouver Island and the mainland completing the east west box. Keep in mind, with a day or two extra, you can run down to Olympia or up to Princess Louisa Inlet.

 For this discussion, we are sticking to the 

core San Juan Island area and what you need to get there.

Obvious (to some) Cruising Basics

You need a boat, but you can rent a sail or powerboat in Anacortes or Bellingham if you prefer, and it doesn't take much experience to qualify.

• Size matters? yes and no.  Bigger is more comfy, costly and feels imminently safer in a storm. As size goes up, so do your skill requirements. Once past about thirty five feet you will find you don't fit at some docks and fuel burns at over twenty five gallons an hour. Smaller is  better at times. Eighteen foot ski and fishing boats or day sailors are very easy to get in and out at virtually all places but with all your food and gear, you could be crowded on board. When packing and provisioning, be honest and admit you don't really need all that stuff you take car camping. Above all, don't let your lack of a perfect boat cause you not to go. Take what you have, you can make it work.

• Bring a dinghy, even a two person inflatable kayak is okay.  You need a way to get to shore where there are no docks. You don't have to carry the dinghy on board, you can tow it everywhere you go. Yes you can beach your runabout and let the tide leave you dry on a beach but bringing a dinghy is so much easier. (update 2025) Lately we have seen inflatable paddle boards used as dinghys and we have done it ourselves so we know they work. 

• Sleep on board, at anchor, at the dock, or in the many park campgrounds. (there are about twenty marine campgrounds, you can camp at a different park every night) If preferred, you can spend every night at a marina or resort and sleep on shore.

• The best weather will be in July and August, but the shoulder seasons have less people and okay weather too.

• I suggest you plan a week, but you can make a weekend work.  If you have a comfortable all weather boat, spend the summer.

• If you rent, don't forget you have to park your car(s) If you trailer, plan on a daily parking fee of around $12.  (Squalicum Harbor in Bellingham is free, even long term) Call harbormaster for current rules.

• See this posting for launch ramps. ---launch ramps with long term parking  This is probably the only real planning decision you need to make before you go, but we have changed our planned take off point as we drove up the highway.  Do not start your San Juan cruise down south in Olympia, Seattle or Everett or Port Townsend or Port Angeles. If you do you will spend much of your time motoring long distances (both ways) My advice is to start in Bellingham or Anacortes using one of the ramps from the list above.

• You need with you on the boat, a chart, or you will get lost, count on it. You should have a list of parks, marinas and resources preferably marked on your navigation chart. Get this chart. Noaa # 18421  -  We use noaa chart # 18421 you can see it by clicking here or anywhere charts are sold.  Navigation charts do not show what's on shore, (roads, city's, marinas, parks, etc) so we carry a highway map as well.

• Don't run out and buy an expensive chart plotter. At minimum, you need a paper chart, a  portable GPS and a compass, your smart phone will probably do.  All boats need a depth sounder or you are risking an expensive grounding.

Sample itinerary: #1. Begin at Squalicum Harbor in Bellingham (open 24/7).

2. Head for Friday Harbor and get a slip for your first night or every night (they take reservations).  

3. Use Friday Harbor as your base, returning every night to your own slip with power, water, restrooms, on shore restaurants and entertainment. 

This plan will work for virtually all boaters regardless of  gear, experience or creature comfort requirements. None of the Marine State Parks have reserve-able docks or anchor buoys, everything is first come first gets it. This means you should plan on anchoring and using your dinghy,  it also means when someone pulls out you may grab the spot at the dock. Rafting is the term  used when several boats tie together at anchor or the dock.

Sample itinerary: #2. Begin at Squalicum again but this time head for Matia or Sucia. 

• Tie up to the dock at Fossil Bay (Sucia) or anchor.  Sleep on the boat or camp on shore.

• Next, Jump over to Stuart, repeat and then Roche Harbor or Jones, then to Friday Harbor, then Fisherman Bay. This itinerary will make sure you have a shower and food store available (Roche and Friday) when you really need and want both.  

• Fuel is readily available but you should try to have a minimum range of seventy five miles just to be sure should you encounter adverse conditions.

• How many days you spend at each park is up to you, your car and trailer will be waiting in the free parking lot when you circle back to Bellingham.

• You can do exactly the same cruise, but begin at Washington Park or Deception Pass  (Cornet Bay) and perhaps change the order.

• Search this website for other suggested itineraries.  The possibilities are endless.
• 
  

Get my San Juan Islands Cruise Guide, it  has all the parks, 

marinas, fuel, resources, phone numbers.

 The guide is written specifically for visitors coming by boat. The companion book, the San Juan Islands Travel Guide is written for visitors coming by car.

              San Juan Islands Cruise Guide     -----   San Juan Islands Travel Guide

         Don't be cheap, the books cost less than a meal and will pay for themselves in saved frustration,  making your cruise a real success.

• Lastly, I can't address everything you may want or need to know in a single post, so I suggest you search this site and read some more articles. There are several with detailed day by day itineraries. Next, after becoming more knowledgeable about what and where you want to go and do, set aside a week and go. It really is that easy. The central cruising area is small enough that you can completely change your plans on the fly. You don't need reservations, you don't need a plan, you don't even need to bring food, just grab your gear and boat and hit the road. OH - bring some cash or plastic for, fuel and park fees and that food I just said you don't need.

If you happen to see us on Kraken somewhere, please say hello. We hope to be anchored in Fisherman Bay for the Lopez Island 4th of July fireworks show.

Marine Parks of the San Juan Islands and Surrounding Area

Below is the marine parks list

             followed by reviews, charts, and pictu res

                         in the order listed.

        This is not all the parks, just the ones you may want to make part of your cruising. It's unlikely you can visit all in one trip and still do a decent job of sightseeing. You should plan multiple visits to the San Juans.

Many people choose Jones as their favorite for just hanging for a few days, so Jones is first.
For hiking, Sucia, or Pelican Beach on Cypress Island are the best, but all the parks have hiking trails.

      Some parks are in a convenient location when you need to spend the night and you're between destinations, Saddle Bag, Eagle Harbor, and Odlin would fit this description. 

 Most parks with docks have picnic tables on the floats, which are very handy for extending your living area, socializing, and meeting other boaters.

Ten Best Parks of the San Juan Islands

What and where are the San Juans 

ten best parks?

      Picking the best of anything is asking for an argument but I thought folks planning a visit would benefit from the discussion.

     Let's start by listing my choices in order of best first, first because they have overnight docks,  followed by some pros and cons and a few real world comments.  (hopefully I haven't omitted your favorite)  Keep in mind, we go to all the parks and don't dislike any but  there is no doubt some parks are five star and some are not depending on what we are doing or the weather during that particular cruise.

Cruise the San Juan Islands – Sample Itinerary, Trip Plan, Vacation Guide

"Where are the best places to go and best things to do in the San Juan's?"       

Talk to ten San Juan Islands cruisers and you will get ten different answers to the question,  Each will be correct, or mostly correct. To support their answers, they will offer first-hand exciting personal experiences.  That is why you must gather  the best information, inject your wants and quirks, and then chart your own course to the San Juan's.  
     Our experiences and local knowledge have been earned the old-fashioned way – one cruise at a time. Sailing, hiking, biking and gunkholing, all while immersed in nature have been our reward. 
     This website is a compilation of our travels in five sailboats and two trawlers spanning three decades.
     Along the way we published a cruising guide, “San Juan Islands Cruise Guide,” followed later with a Land and Sea Guidebook, “San Juan Islands Travel Guide.”  My goal for this website and these books is to help boaters, travelers, sailors, and families enjoy the good times we have enjoyed for many years.
     What is the best five-day itinerary?  That's like asking what's the best color.  But there are certain things that our experience and local knowledge will help with.  Sometimes, one just needs a little push in the right direction to get on the right tack, so to speak.  It is impossible in an essay or article to cover everything important to everybody or all the possible places to go.  However, this website does cover every state park, every county park, every public dock, and much much more.  
     You will find many links to pictures and specific posts, all composed for San Juan Island boaters.  Be sure, while reading to click the links and follow your interests. Be sure to use the search box at the top of this page on the left side.

You're invited!

     To help you muddle through this dilemma and provide some interesting reading, please come along with us on our summer cruise in the San Juan Islands.  Of course, you will be taking your own boat since ours is full.  

     Today, we use our laptop as a chart plotter. The program was free online Free chart plotter software but I had to buy a USB antenna for $19.95.  You can get by with a small handheld GPS or even your cell phone but I enjoy the big screen.   I don't want you to get lost if we get separated, or your battery is dead, so you should pick up a paper chart and a compass.   chart #18421 I carry a colorful roadmap with us as well.

    Let's get on the same page and assume this is your first boat trip to the San Juan's, and you are in a trailerable sailboat with a 5-6 mph speed.  There are five or six starting points we have used but only three are preferred.  They are Cornet Bay in Deception Pass, Cap Sante in Anacortes or Squalicum Harbor in Bellingham.  If you have a fast powerboat or are coming up from the Seattle direction you will want to make time and distance adjustments.  We will plan  to sleep on board but use bathrooms on shore. Okay, let's go. ----- We have narrowed it down to about twenty parks to choose from for the first night, and that's not counting the marinas at Friday Harbor, Roche Harbor, or Rosario.   Not to worry, I have a plan >>>  all the parks and then some

      Sometimes when we plan a vacation trip to the San Juan's,  we try to make a great circle route because it saves time and resources. But this time we're going to decide where we go, as we go. We will see how that non-plan works out.  Certain people on the boat have expressed a desire for hot showers, I guess we will see how that works out too. Since we may travel all the way across the San Juan's and back, your boat will need a minimum 75-mile range. Fuel is readily available everywhere but smart skippers figure one-third of the miles out, one-third back, and a third as a cushion.  If your fuel tank is a little small you can tie a five-gallon can on deck.  Knowing you have reserve fuel will ease anxious thoughts and ensure you have a great visit.  Shall we also assume that you have a seaworthy vessel with all safety gear?  If not, correct it before we head out, or stay home.  Life jackets for all

Plan as we go itinerary:

Cornet Bay Launch Ramps

        Let's begin at Cornet Bay in Deception Pass Park.

  However, after reading this post, I suggest that you search this website and check out the other launch locations. Some may fit your plans better. launch points Also, search the other parks and marinas and things to do.  It is easy to overlook a great place or mini adventure that will make your cruise the best of all.  I chose to launch at Cornet Bay this time because I really enjoy the pass scenery.  The dock and the long-term parking are ideal.  Plus being able to take off or return from both directions 24/7 opens up even more possibilities when not having a firm plan. If I was heading for the Sucia, Patos or Matia Island area first off, I may have chosen Squalicum Harbor in Bellingham but where we end the cruise may dictate where to begin.

16 public floats and docks you should know about in the San Juan's

Where to Find Public Docks other than State Parks

When visiting the San Juan's many of us head for the great marine state parks, and for good reason, that's where the floats, campgrounds and amenities are located that vacationers desire.

However, if you want to get off the boat and see something other than campers and boat people you have two choices. #1 dinghy ashore somewhere or #2 find a public dock and head out. This list and description of San Juan area docks excludes the state parks because most marine state parks are landlocked or waterlocked leaving visitors with no opportunity to explore beyond the park.

Sixteen public docks, organized and listed in no particular order.

.     Obstruction Pass, 

This county float and boat ramp is located just inside Obstruction Pass on the southern tip of Orcas Island. 

 Nearby pass traffic wakes make this a punishing place to tie up even for just the two hours allowed, however rendezvousing with friends on shore or heading out on bicycles for a strenuous ride to the top of Mount Constitution may be just what's needed to round out a perfect cruise. Tip: For longer visits, anchor nearby after dropping off passengers and bikes, then drag the dinghy up onto the float or shore. Your boat will thank you when you return

Obstruction Pass county dock in red circle at top
Blakely's at bottom

     Blakely's 

Blakely's is a conveniently located fuel dock/deli store about halfway between everywhere we go in the San Juan's. 

They are just inside Peavine Pass on Blake Island. On shore is a small store and deli bar famous for ice cream cones to savor on the lush waterfront lawns. Grazing deer share the lawn so watch your step. The dock is rather long with plenty of room on both sides to tie up big and little yachts and still not interfere with those getting fuel. They offer overnight marina slips in a very protected tiny cove. The island and roads are private so boaters may not leave the marina property.

Fuel and store dock at Blakelys is long and you may tie up on either side to avoid wind or current issues.

     Deer Harbor

 Deer Harbor and community is on the west end of Orcas Island at the end of the road. 

 You may purchase fuel and snacks, get ice and rent a slip. The county dock is actually the same dock as the fuel float. Simply tie up for the allowed two hours out of the way just past the fuel dispenser.  The county section is painted yellow and accommodates several runabouts, sailboats, or one large yacht. This is an excellent jump-off point for kayakers heading for Jones Island or for dropping off people catching the San Juan Transit minibus. The bay out front is calm and rogue wakes are few, anchoring room is abundant, and restrooms, showers, and laundry are on the wharf.

If you squint, and look under the main wharf at Deer Harbor, you can see the yellow painted county dock.

Where are the Public Boat Ramps in the San Juans - just the basics to get your boat in the water

      Buried in this website are itineraries, helpful hints and everything you need to get going to the San Juans.

         And that's the problem, it's buried.


Some of us don't need anything but to be pointed to the boat ramp.


This post points the way.
BOAT RAMPS TO THE SAN JUANS   << hot link, clickety click!

Should you take your boat trailer on the ferry and get off somewhere? 

 NO! - I don't recommend it unless you are going to a resort that has a ramp and you plan to rent a cabin -- plan on spending substantial time waiting in  ferry lines.  Be forewarned, some so-called local ramps are simply sandy beaches with no docks. Plus the ferry rates for trailers - ouch.

If you carry kayaks on the roof, riding a ferry makes good sense.

  My #1 suggestion for kayakers that don't want to paddle across Rosario Strait -- go to Deer Harbor on Orcas Island, park your car and paddle two miles to Jones Island for a night or two camping.

Let's say you carry a kayak on the roof or trailer a day-sailer and plan on camping on shore, and you don't want to deal with ferries - do this.

  Drive to Washington Park in Anacortes, (campground and ramp) set up your camp, splash your boat and sail or paddle to either Pelican Beach on Cypress or Saddlebag Island.  Spend the night or come back each evening.  Using the currents, you can avoid difficult paddling or  fluky sailing if that's what works for you.

Hint, use the search box and search Saddlebag or Cypress or Pelican Beach or Deer Harbor, or Jones.

Public ramps with floats and parking open 24/7

Step by Step guide and Itinerary for making that Dream Boat Trip to the San Juan Islands

     This cruise itinerary is for the first timer with the boat on a trailer. 

The novice skipper with family for crew will find this article contains just what's needed to get going on that long talked about trip to the San Juans. While this is a step by step action plan to follow, some skippers do not need all the steps and prodding and so they should skip ahead to    

  Day #1.  for the daily itinerary  

For the rest of us, these steps are important, so I've numbered them.
  Before you go

1. Right now, go put two marks on the calendar. Mark the day of departure from home and one week or so later mark the day your returning. Do it now or forever hold your peace and admit your not really going boat camping in the San Juans.
2. Go to your local chandlery or go online and purchase a big color map or chart of the San Juans. I'm not telling you which one, it doesn't matter, just big and one you like to look at.
3. Got the map? Good now nail it to the wall where you can see it all the time. Do it now!  OK, the hardest part is over, you have now made a commitment to yourself and crew. Your really going.  Kick back a little, relax, do some day dreaming.  Your trip (cruise, vacation, what ever you want to call it) is already well underway. By now you should be  getting into the  excitement that comes with planning and preparations.    Note:   Don't let worry and stress build up, your really going to enjoy this outing and it will be easy, trust me  (heh, heh, heh)  Relaxing good times should be part of the  process that started when you made the X on the calendar. Remember, on this cruise there are no deadlines to meet, no times to beat, no "sorry no vacancy's" to worry about. You are on your own schedule to do as you please. What could be better besides a gourmet chef and staff.  Study the map with your crew, locate Friday Harbor, Jones Island, and Squalicum Harbor in Bellingham. Do some internet searches, read peoples reviews.
4. Start compiling a list of supply's and provisions that you think you need. Click here for help with that list >>  Cruisers Packing List this list may be a little too much, so pick and choose.
5. Start making a list of boat and trailer, must do's (like greasing the wheel bearings) I mention wheel bearings because there are a few "must do's" that will potentially ruin your plans, having a bearing go out from your neglect is avoidable, so are boat motor issues. We once went with an untested, worrisome diesel motor, and sure enough it quit, but because of suspected problems I had mounted an outboard bracket and brought my trusty 7.5 hp Honda along which not only saved the trip, but allowed us to extend it a few days.  Another time with a different boat I towed a dinghy which sole purpose was to carry a spare outboard just in case.   Another mistake not to make is inadequate packing for inclement weather, (hope for warm sunny days, but plan for cold windy rain).  Don't forget seasickness pills (Dramamine)  or other medication, one persons needs could ruin the trip. There must some other must do's that are particular to your family??? Spare tire for trailer! Hmm!
6.  #5 was a downer, lets lighten up.  You need to bring an ice chest if your boat has none, maybe two, plan on ice lasting 3-4 days and then resupply time.  For a food menu, you should plan to eat well, especially if you have bad weather when hot food hits the spot and improves spirits. Sandwiches are easy to prepare and bring lots of trail mix and snacks.  You will need lots of water, don't plan on any being available once you shove off. We bring our water in 5 gallon jugs and pour it into smaller bottles
7. You will need a propane cook stove and fuel bottles to last entire trip (propane is $7+ in the islands)
8. Garbage:  I need to mention it now after suggesting you bring all the junk food.  Your little boat will quickly become overrun with trash, bring bags, the outside islands have no garbage service. Think about all that convenience food packaging material I just told you to bring.  Some of the packaging may be left at home. Prepare things in advance and freeze meals ready to go as they thaw (2-4 days in ice chest)
9. Under boat equipment, the list is very subjective so lets just list a few must haves.  PFD's all around and all coastie required equipment (whistle, type 4, fire ext., registration, lights, etc) Plus I think you need a minimum of two anchors and extra rode, extra fuel if your tank is small.  Your boat should have a range of 75 miles. The rule is 1/3 outbound, 1/3 to get back, 1/3 for reserve. It could be 25 miles between fuel stops, so a 75 mile range gives a good cushion. Many boaters simply tie 5 gallon jugs on deck.  If your boat is open and it really rains hard, bring a tarp and ropes to lash it down. You may sleep on shore so a tent is needed. You need a hand bilge pump and a bucket (they look like a big suction tube and flex hose.
10. Bring a GPS,  You can get by without one but they are fun and really are useful. Some phones have apps available. Bring your cell phone (they work good almost everywhere) Bring the map or chart nailed on the wall or better yet go buy a real navigation chart with depths and rocks all located.  Bring a compass (hand held is OK) Bring a vhf marine radio (you can buy a portable battery one for about $100.   
11. The boats loaded your ready to go. Don't forget to tell someone where your going, and when to call for help if you don't check in as planned. That person could be a friend or relative that doesn't panic over  icky weather reports.  They should call the San Juan County Sheriff or Coast Guard if needed, or someone you have prearranged to call, 911 works too. Remember, your plans may change as the week progresses, but you can check in with a cell phone call most of the time.
