Sailing Passage & Anchoring Pack
Anchoring, under-keel clearance and passage planning
The decisions the calculators can't make for you: minimum scope by bottom type and length of stay, what each bottom actually does, swing-room tables, the water you need above charted zero once swell is allowed for, where the Rule of Twelfths cannot be trusted, and how much longer a passage really takes once tacking and tide are counted. 7 pages, printable, with a fill-in passage plan and anchor log.
