HELM is built for it — and for the years after it.

HELM is a revision app for the MCA Officer of the Watch (Yachts) less than 3000gt certificate. The bridge between deckhand and officer.


MOCK EXAMS — TEST WHAT YOU KNOW

Timed mock exams under real conditions, across the whole syllabus: multiple choice, true/false, matching and fill-in-the-blank, with a worked explanation on every question. Sit a full paper or drill a single module.


THE ORAL — REHEARSE IT OUT LOUD

The AI Oral Examiner runs a spoken mock oral assessment. It presses for detail when an answer is thin, holds you to the standard an examiner would, and gives you a written breakdown afterwards: what you got right, what you missed, and the rule you should have cited. Four sittings a month, without booking anyone's time.


LEARN THE SYLLABUS PROPERLY

Sixteen modules covering the full OOW Yachts syllabus:

• Navigation & Passage Planning
• COLREGs — Rules of the Road
• Lights, Shapes & Sound Signals
• Buoyage — IALA
• Bridge Watchkeeping & BRM
• Meteorology
• Stability & Watertight Integrity
• Yacht Construction & Equipment
• Anchoring, Berthing & Ship Handling
• Tenders, Toys & Guest Operations
• Safety & SOLAS
• Firefighting & Emergencies
• Pollution Prevention & MARPOL
• ISM, MLC, Flag & Survey
• Communications & GMDSS
• Signals & Distress

Lessons are typeset to be read rather than skimmed, with diagrams drawn to explain rather than decorate.


DRILL UNTIL IT STICKS

Spaced-repetition flashcards scheduled by the SM-2 algorithm, so a card comes back just before you would have forgotten it. What you find hard comes back more often.


KNOW WHERE YOU STAND

Readiness tracking across every module, so you can tell the difference between feeling ready and being ready.


FOR JUNIOR OFFICERS, NOT ONLY CANDIDATES

Passing is the start, not the finish. HELM stays on your phone afterwards as a revision companion: the full text of the Rules, lights and shapes, buoyage, signals and the sea scales, all searchable and all offline. Junior officers use it to keep the theory sharp between tickets and to check a detail without hunting through a publication.


WORKS AT SEA

Lessons, flashcards, mock papers and the whole quick reference run in airplane mode. Mid-ocean, in a lift, on a delivery — it does not matter. Only the AI Oral Examiner needs a connection.


QUICK REFERENCE, ALWAYS TO HAND

• COLREGs — Rules 1-38 and Annexes I-IV, full text, searchable
• Lights & shapes — an interactive atlas, every examinable configuration from three aspects
• IALA buoyage, Regions A and B
• Sound & light signals
• International Code of Signals — single and multi-letter
• VHF channels
• Beaufort scale and Douglas sea scale
• Cloud recognition


START WITH COLREGS, INCLUDED IN FULL

The entire COLREGs module — lessons, flashcards and mock exam questions — is yours from the moment you install, offline, without an account. A subscription unlocks the remaining fifteen modules and the AI Oral Examiner.


IN YOUR LANGUAGE

The interface is available in Afrikaans, Arabic, Chinese (Simplified), Croatian, Dutch, English, French, German, Greek, Italian, Polish, Portuguese (Brazil and Portugal), Russian, Spanish and Ukrainian.

Syllabus content stays in English, because English is the language of the exam. A built-in glossary gives you the English term with its definition in your own language, so nothing is lost in translation on the day.
