Christopher Brellis. Wind Heel

Product Development

Wind Heel.

A boat attitude instrument for sailors. Rest your phone flat on deck, top edge toward the bow, and it reads heel, pitch and heading straight off the phone's own motion sensors — alongside G-force on the crew and GPS speed over ground. Record a sail as it happens, then play it back and watch a 3D boat replay the whole thing.

Currently in development — coming soon for iOS & Android

Live screen with heel, pitch and heading gauges, plus speed, G-force and peak G
My boat profile with a 3D drawing that follows the boat's type, rig and keel
