SurgeTrac

SurgeTrack is the all-in-one companion app for sailing regattas — built for skippers, crews, race officers, and spectators who refuse to miss a single tack. LIVE RACE VIEW • Watch the fleet in real time on a 3D/2D WebGL course. • Live leaderboard with SOG, COG, leg progress, and online status. • True wind compass and dynamic laylines for tactical insight. • SOG rainbow trail to spot who's gaining — at a glance. ON-BOARD TELEMETRY • Stream GPS, heading, wind, and speed via the STUP v2 binary protocol. • 15–20 bytes per sample, sub-3 ms server RTT — no lag, no dropouts. • Master/standby auto-failover keeps your signal alive through patchy coverage. • 30-second buffer smoothing keeps the live view fluid even on weak networks. RACE CONTROL • Set up courses, marks, starts, and finishes from boat or shore. • Pin and RC-boat start line with dynamic bias. • Frame-by-frame Catmull-Rom replay for post-race analysis. • Export race reports (PDF) for juries and protest hearings. BUILT FOR THE WIND • Co-designed with pro sailors and World Sailing officials. • Works offline — cache the course and sailing instructions before you cast off. • Metric & imperial units, multi-language UI. • Encrypted auth, JWT-secured, role-based access (spectator / crew / officer). Whether you're calling tactics from the rail, trimming a spinnaker at the leeward mark, or watching your kid's Optimist race from the clubhouse — SurgeTrac puts the whole regatta in your pocket. Get on board. SurgeTrac.
