Weather: Even when it's officially summer, expect a changeable, late-fall climate and take a layered approach to clothing. Bring good foul-weather gear and boots that will allow you to get in and out of the dinghy without shipping cold water. The charter boats from Sailing Inc. are well equipped and set up with heaters, dodgers, and all the navigation equipment and galley gear it takes to enjoy life afloat. Calms are usual, so cruising boils down to either slow but delightful sailing or a decision to speed things up by motorsailing. Watch your fuel, though, and always leave an adequate supply to sprint to safe shelter if a big low threatens.
