Race Marks

Share your boat with crew, free. DBSC & ISORA 2026 sailors: Digital Course Cards included. Race Marks Pro — race timer, auto-advance & more — to buy.

Race Marks puts your sailing club's course cards in your pocket. Select your club, pick today's race, and see every mark on the course — name, buoy shape, colour and rounding direction — before the start gun fires.

COURSE CARDS & RACE DOCUMENTS Browse official Sailing Instructions, Notices to Competitors and course cards published by your club. No more squinting at a rain-soaked printout taped to the boom. Course cards show the ordered mark sequence with buoy type, colour, letter and rounding direction for every leg.

MARK-BY-MARK NAVIGATION Live bearing and distance to the next mark, updated in real time from your phone's GPS. Race Marks advances through the course automatically as you round each mark, or tap to advance manually if you prefer. A preview bar shows what's coming next so you can plan your approach.

PRE-START DASHBOARD See the full course laid out with every mark before the sequence begins. Know exactly where you're heading before the gun fires.

RACE COUNTDOWN TIMER Configurable countdown synced to your class start sequence. 5-4-1 or custom intervals. Keep your eyes on the line, not your wrist.

CUSTOM COURSES Build your own courses from your club's known marks for practice sessions, informal racing or training days.

WORKS WITH YOUR CLUB Race Marks works directly with yacht clubs and sailing organisations to make sure their race documents and course data are up to date. If your club isn't listed yet, get in touch — we're adding new clubs regularly.
