I have seen the article about something like: "Ten Places To Avoid In The San Juan Islands." For the most part, that is for chartered boats with inexperienced skippers. When we bought our C-Dory 25 in 2006, the San Juans were one of the first places we went. We have come back a lot since that time; in fact, this is our 5th year working for a whale watch company on San Juan Island. I drive whale watch boats daily in the San Juan Islands (and further).
You don't want to have a cavalier attitude about cruising in the San Juans, but it is a very boater-centric area, AND one of the most spectacular places to cruise a boat like yours. There is an annual C-Brat Get Together in Friday Harbor (often called the commercial/retail hub of the San Juans) - they come here because of the great cruising.
Have current charts, a good chartplotter (and a back-up, such as Navionics on a phone or table). From the 4th of July through mid-September, the chance of fog is slight, but can certainly happen (so radar is handy, but not essential, as long as you are flexible with your timing). Not much rain. The weather is generally a gorgeous 70s and sunny. (This is also part of what brings us back.)
You will want a tide/currents booklet and I suggest a cruising guide like Waggoner's. Yes, there is tide and current to deal with, but with proper materials, it isn't a dangerous situation.
I have met people who have run from the mainland (22 miles from Anacortes to Friday Harbor), boated around San Juan Island, ran to Sucia, and felt they "did" the San Juans. There are SO many interesting places to visit by boat - good anchorages, state marine parks with mooring balls, and nice marinas. From anchoring just off English Camp (site of "the Pig War") or in Blind Bay (off Shaw Island), to living large in the marina at Rosario Resort or restocking on groceries and restaurant choices in Friday Harbor. Watch the striking of the colors ceremony in Roche Harbor. Hike to the lighthouse, one room schoolhouse, and "the Treasure Chest" on Stuart Island.
A dinghy will open up possibilities for anchoring out, dinghying in.
You may want to bring your passports and check out the neighboring Canadian Gulf Islands or spend a couple nights at the Inner Harbour in Victoria (Vancouver Island), about 23 miles from Friday Harbor.
Look for bald eagles, Stellar Sea Lions, and, of course, maybe get the chance to see Killer Whales. There are laws mandating minimum distances and speeds around the Orcas, and "ignorance of the law" isn't an acceptable excuse to Enforcement (there is a sidebar article in Waggoner's about the distance laws - watch what the commercial operators do, and don't try to get too close or cut off another boat's view).
Summer weekends are busy. The 4th of July is a zoo.
We spent 3 summers living on our C-Dory in Friday Harbor, and cruised here a couple summers before that. We are currently "land based" on San Juan Island... it is a beautiful summer day here!
Yes, we love this area. Summertime, it is boaters' paradise. You have a great boat. Sounds like you have a smart attitude. Spend a day, and you will see how beautiful it is. Spend a week, and you will get a glimpse of the boating wonders here. Spend a month cruising the area, and you will be hooked.
Come experience the San Juan Islands.
Best wishes,
Jim
P.S. Look through our photo album here to see some of the great boating to be had in the San Juans.
