Three ways to use Race Marks

Pick the one that sounds like you. Each page is written for that job and nothing else.

I race with my club

For Local Sailors

Club racing, Wednesday nights, weekend series. You want to know the course, the marks and when the gun goes — without a laminated card and a torch.

  • Your club's course card, decoded
  • Ordered marks, shapes, colours, roundings
  • Start countdown for your class
  • Works on a phone alone — no instruments needed

For Race Committees

Race officers, sailing secretaries, club committees. Publish the course once and let every boat read the same thing — then change it on the day when the wind does.

  • Course & mark authoring with conflict checks
  • Draft privately, publish as a versioned bundle
  • Race-day overrides, live, with an audit trail
  • Share a live race link — no login
See the committee tools → I'm chasing the numbers

For Serious & Pros

Instrumented boats, offshore programmes, crews who debrief. Know the apparent wind on every leg before the gun, and what actually happened after it.

  • Per-leg apparent-wind prediction from your polars
  • Leg-by-leg polar debrief after the race
  • NMEA 2000 / Signal K instrument integration
  • Tide set & drift, wind vs instruments

What Race Marks is

Clubs publish sailing instructions, course cards and race programmes. Race Marks transcribes that into a digital, filterable form, ties it to the marks' real positions, and puts it on the boat — so “Course A4 for Cruisers 2” becomes an ordered mark list, a set of roundings and a countdown that already knows your start time.

Alongside your club, not instead of it

Race Marks links to the documents each club publishes and re-hosts nothing without agreement. The club's own notices stay the definitive word on race night.

Tuned to where you sail

Wind, tide, wave and sea-temperature observations come from the right sources for your venue — Met Éireann, the Marine Institute, Open-Meteo and Irish Lights today.

Your phone is the instrument

Modern phones lock onto more positioning satellites, on more frequencies, than most marine plotters. Race Marks is built to use that headroom.

For many club boats the single biggest performance gain isn't better sails or tighter trim — it's having the crew ready for the next manoeuvre well before the mark, and hitting the laylines and start lines at the right moment. That's what Race Marks is for. Chris Miller, founder, Digimill — launch release, May 2026
