No credit card required · Free tier, always
How Berthr works
From the first invite to the final log entry — the operational side of sailing, handled.
Add guests, set a trip date, and Berthr sends SMS invitations automatically. Guests reply YES or NO by text — no app, no account required. You see who's in on the dashboard in real time.
Berthr sends the invite the moment you confirm a trip. Guests reply YES or NO — no link to click, no account to create, no app to install. RSVPs and reminder messages are handled automatically.
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.
Here's what to pack for an overnight on Solstice:
The boat has bedding for 4. Any other questions?
Every confirmed guest gets a link to the trip gallery in their welcome SMS. They upload from their phone, you keep the best ones. Organized by trip, no shared albums to manage.






Your captain's dashboard gives you a live view of upcoming trips, confirmed guests, and pending RSVPs — all at a glance. Manage trip details, guest profiles, and crew from one screen. Built as a PWA, so it works at the dock or at anchor.
A proper captain's log — voyages with multi-leg support, engine hours tracked as a running meter, and boat events like maintenance, fuel, haul-outs, and winterization. Weather auto-filled from historical data.
"The chatbot answered 40-odd guest questions last season without me touching my phone. That alone was worth it."

No. Guests interact entirely via SMS and a mobile web link — no account, no app store, nothing to install. Less friction for guests means more RSVPs for you.
SMS is included in Crew and Captain plans — just use it. Invites, reminders, and replies all flow through Berthr. No Twilio account or third-party setup required.
A Claude-powered assistant you configure with your boat's details — marina, parking, what to bring, trip info. Guests ask it anything before or after a sail, by text or on the web.
A full captain's logbook — voyages, multi-leg passages, engine hours as a running meter, and boat events like maintenance, fuel, haul-outs, and winterization. Weather auto-filled for each sail date.
Plans are annual. If Berthr isn't for you, the Free tier is always available and your data stays intact. No surprise auto-renewals.
Yes. Guest data is stored securely, never shared or sold. Any guest can opt out of SMS at any time — managed directly from your dashboard.
Get started free. The Crew tier takes about ten minutes to configure — your boat details, a couple of guests, and your first trip.
