berthr

Stop chasing RSVPs on WhatsApp. berthr handles invitations, crew coordination, guest questions, sail tracking, and your captain's logbook — so you can focus on sailing.

Stop running your boat on WhatsApp.

berthr handles the operational side of sailing — invitations, RSVPs, guest questions, and crew coordination — plus live sail tracking and a captain's logbook you'll actually keep.

Invites & RSVPs, handled Create a trip, add your guests, and berthr sends SMS invitations automatically. Guests reply YES or NO by text — no app, no account, nothing to install. You see who's confirmed in real time. Send a provisions list so everyone knows who's bringing what.

Crew Coordination Post an open sail or send a crew request and let your crew self-select. First to reply YES gets the spot. Perfect for race days when you need bodies fast — crew see open slots on their profile page and claim them directly. No group chat required.

Your boat, with a brain An AI assistant trained on your boat answers guest questions 24/7 — marina directions, what to bring, seasickness tips, overnight packing. Configure it once, it handles the rest. Guests ask by SMS or web chat.

Guest Directory Your full roster with dietary restrictions, motion sickness flags, emergency contacts, and experience level. Everything you need at the dock.

Live Sail Tracking
Hit record when you leave the dock. berthr captures your track, speed, and heel angle all the way home, pulls in the day's weather, and drops it all straight into the logbook — replay the route on a map, check your heel chart, see your top speed and the conditions you sailed in. When the trip wraps, your guests automatically get a recap with the track and photos, and you can share a story-ready card to Instagram or the group chat.

Captain's Logbook Voyages with multi-leg support, engine hours tracked as a running meter, and boat events — fuel, maintenance, haul-outs, winterization. Weather auto-filled from historical data for every sail.

Trip Photos Every trip gets a gallery. Guests upload from their phones, you keep the best ones. Organized by trip, no shared albums to manage.

berthr runs the guest list, the crew, and the log — not the navigation. That's what your chartplotter is for.
