Cooler on the Mac and on ProMotion iPhones and iPads: a Graphics setting on the planning chart — Full, Smooth or Cool — and sixty frames a second instead of a hundred and twenty. Mooring balls and channel marks are solid. A hull cannot pass through one; a nudge is not a collision. The tender goes anywhere: in a yacht slip she lies against the finger, and one line makes her fast. The Monohull 49 fuels at Road Town. The Sail cat 55 is kept off the Nanny Cay slip she does not fit. The tender's picture in the boat picker, without the block under her.

Two sheets: trim the main and the jib apart, back the jib, and heave-to. Two departures: leave the slip at Road Reef and at Nanny Cay and take her out to sea room. Over 400 exercises: twenty-two harbors, eight boats, fifty-eight berths, every one tested end to end in every boat that fits. Road Reef and every alongside dock: the finish mark now sits a fender's width off the timber in every boat, so your lines hold you in it instead of pulling you out. The run to the WT and the Bight no longer stutter, and Soper's Hole opens without the freeze. Every brief shows the harbor edge to edge. Spanish Town rebuilt from the skipper's aerial, with two approaches. Bitter End's hills back on the land. Sitting and Standing views at the wheel. TACK and GYBE coaching on deck.
