"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 once, and add your own practice sessions. Every event is ready for crew to respond to.
Crew mark themselves In, Maybe, or Out for each event in seconds, from their phone. No account, no app store.
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.
Automatic email nudges before each event so nobody forgets to respond. 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 only what they need to RSVP, on their phone, with no account. Both sides update in real time.

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: we recommend crew bookmark the link or add it to their home screen on first visit (the app will prompt them). That way they can re-open their RSVP page anytime without 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.
Yes, within your boat program. Other boats cannot see your crew or your RSVPs. Strict data isolation between programs at the database level.
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.

Proteus Marine Intelligence Systems builds tools that make running a boat simpler. We're a Maryland company sailing out of the Chesapeake, and we build the software we wished we had on our own boats.
Proteus Crew is our first product. It's the start of a broader family of marine intelligence tools. It stands on its own, and it does one thing exceptionally well: it gets your crew squared away.
