SailDash

Sail Dash is a two-device coaching dashboard for dinghy training. It supports Optimist, ILCA/Laser, 420, 29er, Topper, RS Feva and more. ON THE BOAT The sailor's phone becomes an instrument panel: big, monospaced readouts of speed, heading, distance to the next mark, bearing, and VMG. Numbers are sized for arm's-length legibility, the screen stays bright and awake, and recording keeps running in the background so a pocketed phone never loses a session. Pair an external GPS puck (e.g. Garmin GLO 2) to record higher-rate tracks, and get an alarm if the GPS signal goes quiet mid-session. ON THE WRIST The Apple Watch companion shows the start countdown, your speed, coach messages and a live tack light, so the phone can stay stowed for the whole sail. ON THE RIB The coach sees every sailor in the session on one screen: live speeds, headings, a tack light that scores every tack as it happens, and tile colours that match each sailor's sail number. Drop a top mark at the coach's position, or lay out a full virtual course on the map with draggable marks and a finish line. Every sailor's panel points at the next mark. RACE CONTROL Run a proper 5/3/1-minute start sequence with a flag-coloured countdown banner and audible beeps on every device, or fire an instant start. Sync timers across devices. Tap sailors as they cross the line to record the finishing order, race after race, with a per-race roster. COACH BROADCASTS AND DRILLS Canned and custom messages (STARTING SOON, REGROUP AT RIB, FOLLOW ME) hit every sailor's device with a full-screen banner and audio ping. Quick-tag notes (TACK, GYBE, POOR ANGLE, GOOD VMG, WIND SHIFT, CAPSIZE) log silently to the session timeline for review. A drills library on the COACHING tab starts and ends drills with one tap. SESSION REVIEW After the session, map every sailor's track with detected tacks, gybes, and mark roundings, plus peak speeds, annotations, and coach notes. The wind is read from the boat's own tacks. The speed chart layers all sailors together. Past sessions stay available for later review. WEB DASHBOARD A companion dashboard at saildash.app goes deeper back on shore: session replay, wind and layline overlays, manoeuvre stats, regattas with per-race fleet reports and start-line analysis, share links, and GPX/CSV export. Import tracks from Vakaros and Sailmon devices. BUILT FOR ON-WATER USE Sessions record to the phone first and upload when it reconnects. No signal, no problem. Audio cuts through the silent switch so timer beeps are never missed. Dark and light instrument themes. Free to use. No ads. Built by a sailing parent for his son's training.
