Re: I've become very concerned about the weather...
You should also pick up a copy of this book:
The author sails north to Alaska at this time of year (and later in the book is there in July). He also does a great job of giving you some local history. It was a great sailing travel book.
boats that I sail on regularly: Pearson 28-2, Rondar 505, Yankee 30, Blanchard Junior
