I've had a site in my favorites for a while that has a lot of good info. a lot of it does not relate directly to daysailor, but some does indirectly. the site is L-36.com if you pick up any thing from it great. If not just pretend I never said anything
http://L-36.com is one of my favorite sites as well. Allen has a nice page where he pulls together weather info from many sources as well as lots of good technical stuff on soft shackles, splices, knots etc.
