WeMuster is event software built for sailing clubs. It takes race entries and payments online before the day, then accounts for every sailor on and off the water using NFC wristbands, so the duty officer always knows who is still out.
In partnership with RYA Northern Ireland.
RYA Northern Ireland's youth championships, hosted by the Royal North of Ireland Yacht Club in September 2026, ran its entries and its roll call on WeMuster: 131 sailors, 10 fleets, 18 clubs and 464 tallies out and back, on the phones the volunteers already had. Read the case study.
Setting up a club, building an event and opening entries is free. There is no card to hand over and nothing to cancel. If a club charges for entry, a platform fee applies to money actually collected, and it is shown before payments are switched on. Free-to-enter events cost nothing at all.
WeMuster records who has signed out and who has not signed back in. It cannot see the water and it does not replace safety cover, supervision or a club's own procedures. Clubs should keep a paper backup of the roll call.
