Re: I've become very concerned about the weather...
You might check maps of the Gulf Islands and see if the bike would be useful there.
In the San Juans the town is often not near the marinas. On Lopez it is a pleasant 15 minute walk from Fisherman's Bay to the center of town. You can dock in Friday Harbor. On Orcas the town is pretty far from the public marinas though. I haven't spent enough time in the Gulf Islands to get an idea there.
I like to bring a folding bike with me. They are pretty good for the types of rides that I'll do while sailing. On my Catalina 25 one would fit under the V-berth, on my Pearson a Brompton fits nicely on the shelf by the quarterberth/aft-cabin.
I'm no longer participating on SailNet.
