## Hull Speed Description
Hull Speed is a simple speedometer for sailors. It shows your speed over the water in knots — big, clear, and accurate — on your iPhone and Apple Watch, with nothing else to clutter the display.

Built for trimming sails: make a small adjustment, then watch the live trend graph to see if the speed changed.

FEATURES
• Accurate GPS speed in knots, updated every second, using the same Doppler method as dedicated marine instruments — no paddlewheel to foul or calibrate.
• A live speed graph on a steady, fixed scale, so a small gain from a trim change is easy to spot.
• Enter your boat's waterline length and Hull Speed draws your theoretical hull speed right on the graph — see at a glance how close you are to it.
• Apple Watch app with a Keep Awake mode that holds the screen on while you sail.
• Completely private — your location is used only to compute speed on your device, and is never stored, sent, or shared. No accounts, no ads, no tracking.
