Your personal sailing assistant

Know before
you go.

Tomorrow at six, or wait a day? Ava checks every hour of your passage against your boat and your limits, then tells you plainly.

Free while in testing. Free to download, 14 days of Pro, no card. Every warning and the anchor watch, always free.

Stop doing weather homework.

How much time will Ava save you?

34hours

back in your year, to spend on the water instead of on a screen. Plus a Daily Brief every morning at anchor, already done for you.

Your own numbers, set above. It assumes about two minutes to read Ava's answer and its reasons.

2Passage plan

Your limits. Your answer.

Same sea, different crews. A family with a toddler and a delivery crew need different answers. Tell Ava what you are happy with, and it checks every hour of the passage against it.

Ava's answer
Go with caution

    One forecast. Three crews. Three answers.

    • Motorsailing, understood. Ava knows when the engine helps, and counts the hours and the fuel.
    • Your boat, your numbers. Speeds from your own Log, your tanks, your draft. Limits move with the boat you pick.
    • Island hopping in one go. Chain a week of hops and see every leg's answer at a glance.
    3Departure finder Pro

    Filter passages by what matters most to you.

    A week of departure times, scored for your boat. Pick a filter and Ava finds the best time to leave.

    • Passage alerts. Pro Ava tells you the moment a good window opens.

    4Daily Brief

    Your morning check, already done.

    Coffee in hand, one screen, wherever you are anchored.

    • Your anchorage at a glance. Wind, rain, storms, swell, tides and pressure, right where you are anchored.
    • Wind-shift warnings. Know before your anchorage turns rough, and where to move.
    • Storm-aware all year. A tropical storm near your route means Do not go.
    • Cyclone and tsunami warnings. Know who to listen to, wherever you are.
    Ava's Daily Brief: a gust watch for tomorrow morning, cyclone season notes, local rules, and wind and wind-shift tiles
    5Anchor watch

    Sleep through the night.

    An alarm if you drag or lose GPS, even with the phone in your bunk, and a warning when a boat nearby drags toward you.

    • Free, always. No warning is ever behind a paywall.
    • Boats nearby. When an Ava boat nearby drags, the boats around it are alerted.
    • Your instruments on watch. Depth and wind alarms from your own boat.

    One assistant. Your whole boat.

    Ava is not another island of data. It listens to your boat, knows your boat, learns from your passages, and keeps the whole anchorage looking out for each other.

    Your instruments Pro

    Wind, depth and speed, live over the boat's Wi-Fi.

    Your batteries Pro

    Charge and state of your batteries, live from your battery monitor.

    Your boat, known

    Over 500 cruising boats, every figure sourced and the draft never guessed. Then Ava learns your real speeds from your own passages.

    Ava

    Plans, the Daily Brief and the anchor watch, all drawing on the same picture of your boat.

    Boats nearby

    Shared swing circles in the anchorage. When one boat drags, the boats around it hear.

    Your log

    Entries on a timer, your track, engine and sailing time. Share it as a spreadsheet, GPX or KML Pro.

    Local knowledge

    Passes, anchorages and local rules that update without a new app version, and improve every time a sailor says what they found.

    Ava is Tahitian for the pass through the reef: where the lagoon ends and the ocean begins.

    Ava was built at anchor and tested on passage, aboard a cruising catamaran in French Polynesia, by a sailing family who wanted one honest answer before every hop. Its French Polynesian places come from our own passages.

    Questions sailors ask

    Is Ava free?

    Ava is free while it is in testing: every feature is open. After launch, Ava Free stays free for good: every warning, the anchor watch, the Daily Brief, your Log, and 2 passage plans and 1 multi-stop trip a week. Pro adds the planning tools for sailors who plan a lot.

    What happens when the 14 days of Pro end?

    Nothing is charged, because no card was asked for. Ava drops back to Free, and your boats, plans and Log stay. Go Pro whenever you want the extra tools back.

    Why are the warnings never in Pro?

    Because a warning you cannot see is no warning at all. Storms, cyclones, tsunamis, dragging anchors: they reach every sailor, Free or Pro, always.

    What kind of boats is it for?

    Cruising monohulls and catamarans, under sail, under engine, or motorsailing, which Ava treats as a mode of its own. Pick your model from over 500 cruising boats, or set your own figures, and Ava learns your boat's real speeds from your passages.

    Does it work offline?

    Plans, the Daily Brief and the anchor watch you already have keep working. New forecasts need a connection.

    Where does it work?

    Anywhere for offshore plans, the Daily Brief and the anchor watch. In-depth regions, with reef maps, passes, anchorages and local rules: French Polynesia, Fiji, Tonga, the Cook Islands, Niue, Northland in New Zealand, the Lesser Antilles from the Virgin Islands to Trinidad, and the Balearic Islands.

    Where does the weather come from?

    Three global weather models, plus marine and tide models, read hour by hour. Cyclone warnings come from the regional warning centres named in the Daily Brief. Ava shows where the models agree and where they do not.

    Can I navigate with it?

    No. Ava is a planning aid, not a chart. Keep your charts, your own judgement and a proper watch.

    Which phones?

    Android phones and tablets now, in testing with the Wayfinders. iPhone is on its way. Ava is coming to Google Play and the App Store.
