Up to 487 lesson sheets and reference plates depending on your licence — 20 universal subjects, plus your licence's own.
Up to 72 configurations depending on the licence, each flashing its real character, seen from four angles and drawn on its own vessel's silhouette — plus day shapes and national lights.
IALA-A cardinal/lateral marks and the official CEVNI inland signs, with the real regulatory imagery.
Steering & sailing rules and whistle/fog signals, illustrated with practical scenarios.
Channels, DSC/MMSI, MAYDAY/PAN-PAN, flares, EPIRB and the required safety equipment.
Plotting, Cv = Cc + d + D, Beaufort/Douglas, fronts, tides and currents.
Step-by-step knot diagrams, docking/anchoring/locks, and the MARPOL essentials.
We Boat speaks your exam's language. Choose your licence on first launch and the app tailors its content and vocabulary: the Belgian brevet de conduite and inland RPNE/CEVNI rules, the French permis côtier and the Dutch vaarbewijs. Coastal and inland navigation, in one app — and the COLREG/IALA-A content is also useful when preparing the German Sportbootführerschein See.

Train on any subject, by topic or all-mixed. Every answer comes with a short explanation, so you understand instead of memorising.
Sit a realistic, timed exam with an Admis/Recalé verdict and a per-category breakdown — signage, right-of-way and safety weighted like the real test.
A “review my mistakes” mode with spaced repetition, plus an “Am I ready?” dashboard. Daily challenge, streaks and badges keep you motivated.

See all sources & compliance →We Boat is deliberately narrow. Knowing what it does not do is the fastest way to know whether it is for you.
— Candidates for the seven European licences it prepares: the French permis côtier and permis fluvial, the Belgian restricted and general brevets, the Dutch Klein Vaarbewijs 1 and 2, and the German Sportbootführerschein See.
— People revising on their own — between two lessons with an instructor, or after the course has ended.
— Anyone who needs to revise offline, with no account and no subscription.
— Replacing a course or practical training. It prepares the theory, and nothing else.
— Offshore sailing. No celestial navigation, no radar plotting, no secondary-port tidal calculation — the scope stops at the coastal level.
— Italy and Spain. The international content (COLREG, IALA-A, CEVNI) is useful there, but We Boat carries no national regulation module for either country.
— Telling you which licence to take, or how to enrol. It teaches the rules, not the administrative procedure.
Everything you need to know before you start studying.
Seven, each with its own official mock-exam scoring: the French permis côtier and permis fluvial, the Belgian restricted and general brevets, the Dutch Klein Vaarbewijs 1 and 2, and the German Sportbootführerschein See. Pick yours at first launch and the content, the vocabulary and the exam scoring all adapt. The COLREG, IALA-A and CEVNI content is international and also useful when preparing the Italian patente nautica, for which We Boat carries no national module.

A North cardinal mark has two black cones both pointing upward and shows a continuous very quick or quick flashing white light. It means safe water lies to the north of the mark — steer to pass north of it to clear the danger it marks. (IALA-A buoyage system, Region A.)
A sailing vessel under 20 metres, when under sail alone (engine off) at night, may show a single tricolour lantern at the masthead combining red to port, green to starboard and white astern in one fixture, instead of separate sidelights and a stern light. It must switch back to separate lights as soon as the engine is used. (COLREG Rule 25(b).)
The overtaking vessel must always keep clear of the vessel being overtaken, and stays the give-way vessel until she is finally past and clear — even if the encounter later looks like a crossing situation. A vessel is 'overtaking' when approaching from more than 22.5° abaft the other vessel's beam, the sector where at night only her stern light is visible. (COLREG Rule 13.)
A blue cone (point down by day, replaced by a blue light at night) marks an inland vessel carrying dangerous goods under ADN rules — one, two or three cones show the danger category and how widely other vessels must keep clear. It's a different signal from the rectangular blue board used to indicate a course change during a passing manoeuvre. (CEVNI / ADN.)
A safe water mark has red-and-white vertical stripes and a single red spherical topmark, and its light (if fitted) shows a white isophase, occulting, or single long flash. It signals open, navigable water all around — for example a mid-channel or landfall point — and may be passed on either side. (IALA-A buoyage system.)
