Trip calendar
Arrival, casting off, meals, harbour stops and excursions in one place. Entries apply to the whole boat or just to you, and everyone sees changes instantly.
Features
A trip has a hundred little details. Sailto remembers them all.
Anyone who has organised a charter week knows the scattered WhatsApp messages, the spreadsheet nobody updates and the scrap of paper with the kitty that's illegible by day three. Sailto replaces all that with one place the whole crew can see.
The start
One link, and the crew is complete
No form, no invitation emails, no chasing people up.
You create the trip and get a link plus a QR code. Send it to the WhatsApp group or print it in the club newsletter. Whoever opens it creates an account and appears straight away in the crew list. There's no participant limit and no cost — not even for a club flotilla of thirty people.
- One link for the whole crew, via WhatsApp, email or QR code
- New members immediately see the full state of the trip
- The link can be revoked and regenerated at any time
- Works for groups of friends just as well as for club flotillas
Included in every plan
The crew
Who holds which licence, who doesn't eat what, who snores
The questions that otherwise get asked three times and answered wrongly twice.
Every crew member keeps their own profile up to date — with sailing licences and radio certificate, dietary restrictions and allergies, emergency contact and clothing size for the foul-weather gear order. The skipper sees it all on one page instead of piecing it together from a chat history. Nobody has to enter anything they don't want to; the only required field is the name.
- Sailing licences, radio certificate and experience level per person
- Allergies and diets feed straight into meal planning
- Emergency contacts in one place everyone can find in an emergency
- Snorer flag — the one detail the crew really cares about
- Learning goals for training trips
Included in every plan
The money
A settlement nobody argues about on the last evening
Two models, because crews work differently.
In split mode, everyone pays for whatever comes up — diesel, harbour fees, the big supermarket run — and adds it with a photo of the receipt. Sailto works out the balances and, at the end, suggests the smallest possible number of transfers instead of having seven people send money back and forth. If you'd rather pay in up front, use pot mode with a shared kitty and a running balance.
- Record expenses with receipt photo, category and date
- Split between everyone, a subgroup or individuals
- Automatic settle-up suggestion with the fewest transfers
- CSV export for anyone who wants to double-check
- Pot mode with contributions and a running kitty balance
Split mode free · Pot mode with the Trip Pass
The berths
Assign cabins without it getting personal
The trickiest decision of the trip, settled objectively.
Cabin allocation is the one point where the mood can turn. Sailto sets up the boat's cabins as a plan and shows what matters while you assign them — who is flagged as a snorer, who has stated which preference, where a cabin would be overbooked. On the free plan you assign via a list; with the Trip Pass you drag and drop the crew onto the boat's layout.
- Cabin plan based on the boat model, including number of berths
- Snorer warning before the pairing is fixed
- Overbooking is blocked instead of discovered afterwards
- The crew's preferences shown right at the cabin
- For organisations: standard layouts per boat, set up once

The preparation
Shopping and packing lists that don't contradict each other
One list that eight people can work on at the same time.
The shopping list is sorted by category and items can be assigned to people — whoever is in the supermarket ticks things off, and everyone else sees it. Packing lists come as ready-made system templates by cruising area and season; the skipper adds required items on top, and everyone adds what only concerns them. Each crew member sees their own part, not everyone else's underwear.
- Shopping list by category, with assignments and ticking off
- System packing lists for the Mediterranean, the Baltic, summer and early season
- Skipper's required items that nobody can click away
- Personal additions stay private
- Save your own templates for the next trip

The assistant
Meals and local knowledge at the push of a button
Two jobs that would otherwise eat up a whole evening.
The meal planner creates a complete meal plan for the whole trip — working with what's in the crew profiles: crew size, cruising area, allergies, vegetarian or vegan, dislikes. The result can be moved into the shopping list with one click or sent to the crew as a poll. The cruising area info answers the questions you'd otherwise look up in three pilot books: what's the approach like, where is it sheltered, what can you reach on foot ashore.
- Meal plan for the full length of the trip, matched to crew size
- Allergies and diets are taken into account automatically
- The result goes straight into the shopping list or a crew poll
- Cruising area info on approach, berthing and surroundings
- Runs on Claude, the language model from Anthropic

When it matters
Safety briefing and check-in, properly documented
Two essential appointments that otherwise vanish into thin air.
Before casting off, the crew goes through the safety briefing and confirms it by name — with a short comprehension check, so a nod doesn't count as agreement. You see at a glance who is still missing. At the boat check-in you assign areas to the crew and document every existing damage with a photo and timestamp. It's exactly these photos that decide at check-out whether you get your full deposit back.
- Briefing confirmed by name, not just a tick
- Short comprehension check for each crew member
- Assign check-in areas to the crew
- Record damage with photo and timestamp
- Both can be saved as your own template for the next trip
Running them is free · custom templates with the Trip Pass
The memories
Logbook and map — where you sailed
So the trip doesn't only live on eight camera rolls.
The crew writes legs, weather and the stories you'd otherwise forget into the logbook. The Trip Pass adds the map: the route sailed, the recorded track and the planned harbour stops in one view. If you like, you can attach the place where each entry was written.
- Logbook entries with date, leg and weather
- Route and harbour stops on the map
- Track recording while under way
- Entries can be linked to a point on the map

The features that smooth out life on board
Smaller on paper, but on the trip they're exactly the things someone would otherwise have to go looking for.
Crew polls
Six poll types — single choice, multiple choice, yes/no, open question and more, anonymous if you like. One click sends the result to the calendar or the shopping list.
Sea miles log
The logbook produces a confirmation for each person, ready to sign — legs, harbours, total and night miles, plus vessel details and a signature field. The document you're asked for when going for your next licence, instead of a list pieced together after the fact.
Documents
Sailing licences, ID copies, charter contracts and insurance certificates are kept with the trip instead of in eight different phone galleries. Access for the crew only.
Trip Memory
A look back after you return: nautical miles, harbours, days and crew as statistics for everyone, plus a narrated recap from the logbook for Trip Pass and Plus.
Flotilla support
Several boats in one trip, each with its own cabins and its own invite link. Included in the free plan.
Push notifications
Alerts for new polls, expenses and calendar entries without having the app open. On iPhone from iOS 16.4, and only in the app added to the home screen.
Photo gallery
The whole crew uploads their pictures of the trip, sorts them into albums, comments on them and pins them on the map. With the Trip Pass and Plus; photos only, no videos.
No app store needed
Sailto runs in the browser and can be added to the home screen on iPhone, Android, iPad and desktop. No download, no update prompts on board.
For clubs and schools
Boat catalogue with standard cabin layouts, skipper management, organisation-wide templates, your own branding on the invitation page and a dashboard covering the season.
Made in Germany
Developed for the German-speaking market, with the kitty in euros, cruising areas from the Baltic to the Adriatic and support that replies in German and English.
Who it's for
Three kinds of crew, one app
Sailto is built so that private groups see nothing of the club administration — and clubs still get everything they need.
Private crews
Friends or family, one boat, six to eight people
The most common case and the benchmark for how easy it is to use. If you charter for a week once a year, you don't want to learn software. You won't see any organisation features — they simply don't appear in your interface.
- Free, for good, with no crew limit
- A one-off €14.99 for the Trip Pass if you need it
- No club structure, no empty menu items
Sailing clubs
Flotillas of three to five boats, 15 to 30 people
Recurring trips with changing crews and a fleet that doesn't change every year. Boats and cabin layouts are stored once in the catalogue and carried over whenever a trip is created.
- Boat catalogue with standard cabin layouts
- Club-wide packing list and checklist templates
- Club logo on the invitation page
Sailing schools
Professional providers running training courses
Training trips depend on learning goals and preparation being traceable. Learning goals are in the crew profile, safety briefings are documented by name, and the dashboard gives an overview of the season.
- Learning goals and experience level for each participant
- Documented safety briefings
- Utilisation statistics across the season
Frequently asked questions
Questions about the features
Yes, everyone needs an account to take part in a trip — that's necessary so that the kitty, cabin allocation and lists can be linked to a person and nobody can see anyone else's data. Sign-up runs through the invite link and takes less than a minute. It costs nothing.
No. Sailto is a Progressive Web App and runs in the browser on iPhone, Android, iPad and desktop. With "Add to Home Screen" you get an icon just like a normal app, including a full-screen view without the browser bar — just without a download and without forced updates on board.
No. Sailto needs a connection; only the app shell is cached so that it at least opens without signal. Reading or writing data doesn't work offline. Along the Croatian coast and in the Baltic, mobile coverage near the shore is usually enough — on longer passages it isn't. We'd rather say that clearly than promise something.
They are stored in each crew member's profile and visible to the crew — that's exactly what they're for. The AI meal planner reads them automatically and plans accordingly, so nobody has to go round asking again the evening before the shopping trip. If you don't want to share something, leave the field empty.
Yes. A trip can include several boats: each boat has its own cabins and its own invite link, so each boat's crew lands directly on their boat instead of being assigned by hand. The cabin planner shows the boats separately, the trip overview shows the occupancy of the whole fleet. Fleet mode is included in the free plan.
Only the members of the trip you belong to — and only to the extent each feature needs. Nobody but you sees your personal additions to the packing list. There is no public content in Sailto: nothing you enter is visible to strangers or search engines. All data is stored on a server in Germany; we don't sell anything on and we don't use ad trackers.
The meal planner, the cruising area info and the narrated trip recap run on Claude, the language model from Anthropic. These requests cost us real money every time they are used — which is why they are part of the Trip Pass. With a pass the crew has 50 AI requests for the whole trip, with no daily limit.
Yes, several features are built specifically for that: learning goals and experience level in the crew profile, the safety briefing confirmed by name with a comprehension check, and the documented boat check-in. Sailing schools with several boats and skippers choose an organisation plan.
