# Seavilo — Explore by sea. > Tell us where you leave from and on what boat. Seavilo hands you a whole day at sea: the stops, the return time, the fuel, the cost — and a warning when the sea turns. Example — Ajaccio · leaving 09:00 · Cap Camarat 9.0 : 72 NM, 3 h 20 running time, 86 L fuel, €189 estimated cost, 17:24 back by. Heavier sea to the north from 3 pm — sheltered option offered. *A day drafted by Seavilo. Illustrative figures.* ## A day at sea is badly prepared. Marine forecasts live on one site, coves on another, fuel burn in the back of your head. You cross-check by hand, pick a route, and the wind picks up at 3 pm. Then everything has to be redone, at the worst possible moment. - **Three sources, no answer** — Forecasts, charts and good moorings never talk to each other. The cross-checking is on you. - With Seavilo — One answer, where the marine forecast, the coastline and the moorings have already been crossed. - **Numbers you guess** — Return time, fuel, cost of the day: rarely worked out before leaving, often regretted after. - With Seavilo — Distance, return time, litres, euros and remaining reserve, worked out before you cast off. - **A plan that cannot move** — When the sea shifts, a route written the night before never says what to drop first. - With Seavilo — A sheltered variant arrives with its cause and its cost. You decide whether to take it. ## A few minutes for a whole day. You describe the outing, Seavilo puts numbers on it and holds it against that day’s sea. Every trade-off stays yours. 1. **You describe the day** — The port you leave from, the time window, the boat and its fuel burn, then what you feel like: a swim, lunch at a quay, little running time. Nothing else to fill in. 2. **Seavilo drafts and compares** — Several possible days, each with numbers: distance, running time, return time, fuel, estimated cost and remaining reserve. Compare them, move a stop, the numbers follow. 3. **The forecast is read along your route** — Not a city forecast: wind, gusts, waves, swell and visibility at the coordinates of your stops, at the hours you will pass them. If it turns, a sheltered variant is offered with its cause and its impact. It is never applied for you. ## The phone takes over. The prepared day moves to mobile by link or QR code. On board, the screen only shows what is being decided right now. - **The next leg** — Time and distance left, estimated arrival, informative distance to the coast, fuel and cost so far. - **Told when the sea turns** — The forecast keeps being watched while you are out. If it drops suddenly, the alert reaches you on board: what changes, at what time, on which stretch, and the sheltered option. The last update time stays on screen. - **Without a signal** — A map pack limited to the corridor of your route, and the last useful forecasts, stay readable offline. - **Without wearing you out** — 48 px targets and full-sun contrast. Locked-screen tracking only runs if you ask for it. ## For people who go to sea without doing it for a living. - **You charter for the week** — The boat is new to you, so is the coast. You want a day that holds together, not a navigation course. - **You know your boat, not this coast** — You are after the right moorings and a realistic route before you cast off. - **You are the one organising** — You plan for everyone else, and you want to announce a return time without lying. ## At launch **Free to plan your days.** Seavilo is free.

From a departure port, a time window, a boat and that day’s marine forecast, Seavilo drafts several costed itineraries, then hands the chosen one to the phone for navigation. ### How much does Seavilo cost? Seavilo is free at launch and asks for no payment card. Selected affiliate links may earn Seavilo a commission; they are labelled and every booking is completed directly on the partner’s website. ### Where does Seavilo work? Ports and places are discoverable across the Mediterranean and the coasts of Western Europe, from Brittany to the Algarve and the Atlantic islands. Route planning appears only in basins that are actually routable. ### Does Seavilo replace a nautical chart? No. Seavilo is a planning assistant, not a certified navigation system: it replaces neither official nautical charts, nor notices to mariners, nor mandatory equipment, nor the skipper’s decision. ### Do you need a signal at sea to use Seavilo? No. Seavilo downloads a map pack limited to the corridor of the route and keeps the last useful forecasts, which stay readable offline for the whole outing. ### What happens if the weather turns during the outing? Seavilo keeps watching the marine forecast during the day. If it worsens, an alert reaches the boat with its cause, its time, the stretch of route affected and a sheltered variant, which the skipper accepts or refuses. ### Do you need to be an experienced sailor to use Seavilo? No. Seavilo is built for people who charter a boat for the week, owners discovering a new coast, and whoever organises the day for a group. ### When will Seavilo be available? Seavilo is not open to the public yet. The waitlist on seavilo.com sends one single email on launch day. ## Seavilo is coming. Leave your email: one single message will go out, the day the first day at sea is ready.
