"Who's racing Saturday?" Sent to a group chat, answered by half the crew, forgotten by the rest.
Roster management for a club racing program runs on memory, scattered texts, and a spreadsheet nobody keeps current. Crew double-book. The boat shows up a person short. The skipper spends race week chasing replies instead of preparing the boat.
Proteus Crew replaces all of it with one shared, always-current picture of who's aboard for which race or practice. Owned by the program, accessible to the whole crew.
Load your club's race calendar in one tap, add your own practices, and prune the events you're not doing. Dock call moved? Edit the race and every RSVP stays put.
Crew mark themselves In, Maybe, or Out in seconds, from their phone. No account, no app store — each crew member gets a personal link that remembers them, and it works as a Home Screen icon that opens straight to their races.
See the boat fill in real time across the whole season. Know at a glance whether you've got a full crew, or need to make a call.
Two kinds, both automatic: a nudge a couple days out to anyone who hasn't answered, and a race-morning email to confirmed crew with the day's times. Push and SMS on the roadmap. No chasing required.
No signal at the marina? Your roster still loads. Proteus Crew keeps the latest picture on-device so it's there when you need it.
Crew can pick a handle other crew see. Your real roster stays just between you and the boat.
Skipper sees the whole season fill up at a glance. Crew see the races, who's aboard, and their own status — on their phone, with no account. Both sides update in real time.
Works offline at the dock.
Syncs when you're back online.
Everyone sees the same picture.
No "who else is going?" texts.
Set your boat's default capacity, then adjust any single race — a dozen spots for a distance race, six for a Wednesday night. Proteus Crew enforces the limit, manages the waitlist in fair queue order, and promotes crew automatically when spots open.
Add your program: boat name, sail number, home club, and your season's race + practice calendar. Two minutes, once.
Share one invite link. Crew open it, mark their availability, and each automatically gets a personal link that remembers them from then on. No accounts to manage.
Watch the roster fill from your dashboard and head to the start line knowing exactly who's aboard.

No. Crew get a shareable link, tap it, type their name, and start RSVPing. The full app works in any modern mobile browser. No install, no app store.
Tip: once aboard, each crew member has their own personal link — adding it to the Home Screen (the app will offer) gives them a one-tap icon that opens straight to their races, no asking the skipper for the link again.
You can add any race to your season calendar. And any practice session too. Build the calendar that matches your boat's program.
Yes. The race list, crew list, and RSVPs are cached on device. Open it at the dock with no signal. Everything is still there. Changes you make sync back when you're online again.

We do not sell data. We do not run ads. We do not track you across apps. Crew can choose a handle other crew see, so their real name stays just between them and the skipper. See our Privacy Policy for the specifics.
