Reference
The answers you need are not on the internet.
Which of you gives way. What that light means. The Hebrew for the thing the skipper is pointing at. What to say into the radio when it has all gone wrong. These are the questions that come up ten miles offshore, which is exactly where your phone has no signal. So Marinate keeps the answers on the device.
Free on every plan. No account, no signal needed.
Boat-parts glossary
When you know the part but not the word.
Sailing in a second language is a specific kind of hard. The skipper says מנור and points; you know exactly which winch, but not that word. Or you learned it all in English and now you are crewing on a boat where nobody does.
Marinate carries 88 terms across nine groups — sails, rig, deck, hull, ground tackle, engine and systems, safety gear, navigation and handling — each one in English, in Hebrew, and written out phonetically for the times you heard it but cannot spell it.
Search hits all three at once. Type winch or מנור or manor and you land on the same row.
- 88 terms, nine groups — the vocabulary of an actual boat, not a dictionary dump.
- Search in either language — plus the transliteration, for words you have only ever heard.
- Offline — it ships inside the app, so it works where the lesson is happening.
Skipper's cheat sheet
The rules, in the order you actually need them.
You learned all of this for the exam. Then a ship appears on your starboard bow at dusk and the part of your brain that memorised Rule 15 has gone somewhere else. The cheat sheet is one scroll, written for the moment rather than for the syllabus.
Who gives way under power and under sail. The pecking order in Rule 18, with the reminder that it is not a right of way. What the lights you are looking at mean, and what red-and-green together is telling you. Sound signals, including the five short blasts nobody uses often enough. IALA region A buoyage, with the warning that the Americas do it backwards.
- Right of way — head-on, crossing, overtaking; port tack and windward.
- Lights and shapes — what you are seeing, and which way she is heading.
- Sound signals — manoeuvring and restricted visibility.
- IALA buoyage — laterals and all four cardinals.
- Departure checklist — weather, tide, fuel, crew, and someone ashore who knows.
A memory aid, not a substitute for the COLREGs or for your own judgement.
Emergency
Channel 16, and what to say on it
Nobody composes a distress call well. The emergency card puts the channel in type you can read at arm's length, then walks you through the MAYDAY line by line so you can read it out loud instead of remembering it.
The MAYDAY script
Nine lines, in order: who you are, where you are, what is wrong, what you need, how many are aboard. Read it out; do not improvise it.

Why we do not ship coastguard numbers
It would be easy to bundle a list of national rescue numbers, and it would look reassuring. We don't, on purpose. They differ by country, they change without notice, and there is no offline source we could keep honest between app updates. A wrong number dialled in an emergency is worse than no number at all, because it costs you the minutes you spend discovering it is wrong.
So Marinate ships the ones that are genuinely universal — VHF 16, DSC 70, 112 — and gives you a place to store the real ones for the coast you actually sail. Add them once, in harbour, while you can check them.
All of it free, all of it offline
The reference section is not part of Premium and never will be. It costs us nothing to carry and it is the sort of thing that should not depend on whether you paid, or whether you have a bar of signal.
