The race office in your pocket
You volunteer. You are not paid to spend Sunday night scoring, and you should not have to guess at OCS under pressure with the fleet watching. This page walks through a race day as RaceZen RMS will run it.
The call nobody wants to make
A bunched line, a black flag, and a judgement you have to make in a second from a boat that is moving. Then the protest, then the argument in the bar, then the volunteer who decides they would rather not do it again.
Set the course on the water you actually race on
Pick the fleet and the course shape, set the axis and the first leg length, then publish. The marks and both ends of the line are surveyed by their own units, so the fleet races against one shared geometry rather than thirty separate guesses.
Marks that are not reporting are flagged before you publish, not after the start.

Run the sequence without losing a step
The flags for the sequence are in front of you on the committee screen — AP, the class flag, P, X and First Substitute — so the signals and the timing come from one place. On the water the fleet is running off the countdown.
The starting queue holds the next fleet, and the competitor list filters by OCS, started, finished, not started and not present.

The regatta, set up once
Import the entry list from the club's system, review the fleets, build the courses, load the notice of race and sailing instructions, and publish. Sailors join by code or QR.
Up to 100 boats across 6 concurrent fleets, with results, tracks, notices, protests and sign-ons in the same place.

Questions race officers ask
When can our club actually use this?
- RaceZen RMS is in development. We expect it to be available in early 2027.
- Everything else — the app, the mounts and the sailor features — is available now.
- We are booking club walkthroughs before then, so you can see where it is up to and tell us what your race days need. If your season plan depends on a date, talk to us first.
How is the start line measured?
- Both ends of the line — the committee boat and the pin — are surveyed by their own units.
- A base station on the water broadcasts corrections to those units, so the measurement is made metres from the line rather than relying on a network hundreds of kilometres away.
- That one line is then sent to every boat, so the whole fleet is racing against the same geometry instead of thirty different guesses.
Who actually makes the OCS call?
- You do. Every OCS, recall, finish order and finish time is made under the authority of the race committee.
- The system proposes and shows you the measurement behind it. You confirm, override or correct it.
- Think of it as a better instrument, not a replacement race officer.
Do competitors need special equipment?
- No. Sailors bring their own phones and join your regatta with a code or a QR scan.
- There is nothing to hire out, nothing to charge overnight, and nothing to collect back in at the end of the day.
- Race committee equipment — the base station, the committee boat and the mark units — runs on Android phones.
What does the start sequence look like?
- On your screen: the flags for the sequence — AP, the class flag, P, X and First Substitute — so the signals and the timing come from one place.
- On the water: the fleet is running off the countdown, sent from the committee boat and spoken aloud.
- A starting queue holds the next fleet while the last one races, so class, flag and warning time are set once and the sequence runs itself.
- The competitor list filters by OCS, started, finished, not started and not present, so the wet sheet of paper is gone.
What about fleet safety?
- Safety is on the same screen as the race controls, not a separate app somebody forgot to open.
- You see live positions, last known positions, and alerts for any boat that stops responding or stops moving.
- Sailors have three one-tap alerts: becalmed and needing a tow, gear failure, and injured and needing urgent help.
How big a regatta will it run?
- Up to 100 boats across 6 fleets racing at the same time.
- A series is set up once and runs for months in one place, with its own code for sailors to join.
- Results, tracks, notices, protests and sign-ons all live in the same regatta, so nothing has to be rebuilt in a spreadsheet on Sunday night.
What if there is no mobile signal on the course?
- The corrections that make the line accurate come from your own base station on the water, not from a mobile network.
- Sailing solo and local recording work offline, and tracks upload when the phone next has a connection.
- Managed racing and live results do need data, so it is worth checking coverage on your course area — we will do that with you during a walkthrough.
