San Juan Sailing
Hi John,I responded to a similar post a while back so hopefully this will not be redundant. As long as your 20 footer is sound, it should pose no problems for a summertime cruise up here (I live in the San Juans).There are a few things I would do in the way of preparation however. First make sure you have detailed charts of the area and know how to read them. I would also get a couple of good cruising guides and read them before you come. As mentioned in a previous post, the Washbournes Guide to currents is invaluable, as are tide tables, particularly for a small boat and someone not familiar with the waters. Check the chandlery on this site for some of this information. The Armchair Sailor in Seattle (nautical bookstore) will be a good backup. Assuming you are an inland sailor, probably the biggest adjustment you'll need to concern yourself with are the tides. We experience two high and two low tides a day. In the summer the tidal range is 8-10 feet. This means you could anchor in ten feet of water at high tide and be on the bottom at low tide. In setting your anchor, you need to also pay attention to the state of the tide. If you set your scope for low tide depth, your scope could be compromised when the tide comes in. That much water movement sets up strong currents particularly through narrow passes which is why the Washbourne's Guide is important. (A reliable outboard is important for when the wind dies and you are being carried along by a currrent.)The weather is normally pretty settled in the summer but there are exceptions. A typical July day would be sunny and in the 70's during the day and into the 50's at night. However, we can have cloudy rainy windy days where the temperature never gets out of the 50's and it feels COLD. Fleece layers and good foulies are in order.Winds are quite variable though again not normally really strong in the summer. The configuration of the islands is such that you'll be sailing along on a nice breeze and then get into the lee of an island where the wind dies. Thirty minutes later you hit a channel between two islands where the wind is being funneled and you're ripping along again. It's just that kind of place. You probably won't experience winds above 25 knots that time of year. Typically they kick up maybe four foot waves in the open water areas, much less in protected waters. More usual for summer weather would be 10 knots with waves less than two feet.The San Juans are among the best cruising grounds in the world. I hope you enjoy them.
