PROJECT WATCH • LIGHTS & SHAPES • APPROVED VISUAL STANDARD

Lights & Shapes

MASTER VISUAL STANDARD: The Lights & Shapes reference now uses Approved Master Library 03 throughout. Night recognition is lights-only on black; day recognition uses high-contrast black shapes on a light field. The complete verified set covers Rules 21–31 plus the relevant Annex I / II displays, including towing and pushing, fishing, NUC/RAM, constrained by draught, pilot, anchor/aground, dredging and underwater operations, diving and mine-clearance.

The interactive trainer now uses the same Approved Master Library 03 visual language as the reference cards above: lights only on black at night, black day shapes on a clean light field, with aspect used only to determine which prescribed navigation lights are visible.

BEGINNER COURSE • COLREG PART C • RULES 20–31

Learn to read a vessel before you meet it.

Learn to read the AIS picture.

TRAINING ENGINELIVE AISSIMULATED DATA ONLY
AIS IS AN AID — NOT A SUBSTITUTE FOR LOOKOUT. Use sight, hearing, radar where fitted and all other appropriate means. AIS information can be incomplete, manually entered, delayed or wrong.

AIS & Electronic Situational Awareness

Learn what AIS can tell you, what it cannot tell you, and how to use the electronic picture without allowing it to replace lookout, radar or COLREG judgement.

AIS TRAINING FEED00:00:00 UTC
OWN SHIPWATCH ONE
COG012°
SOG7.0 kn
TARGETS8
ALARMCLEAR
DYNAMIC DATA

What changes automatically?

Position, speed over ground, course over ground and—in equipment that supplies it—heading. Class A reports also include navigational status and rate of turn.

STATIC / VOYAGE DATA

What may be manually entered?

Vessel name, call sign, dimensions and type are static data. Class A voyage fields can include draught, destination and ETA, so do not assume every manually entered value is current.

COURSE vs HEADING

Two different numbers.

COG is the direction the vessel is moving over the ground. Heading is where the bow points. Tide, current or leeway can make them differ.

CPA / TCPA

Prediction, not permission.

CPA and TCPA are calculated predictions based on the present motion of both vessels. They support collision assessment; they do not replace COLREG judgement or lookout.

CLASS A / CLASS B

Do not expect identical data.

Class B normally transmits a reduced information set compared with Class A and may update less frequently. Missing voyage fields on a Class B target are not automatically a fault.

LOST TARGET

Old information becomes dangerous.

If transmissions stop, the displayed position can become stale. Treat a lost AIS target as an information warning—not proof that the vessel disappeared.

COLREG RULE 10 • MCA MGN 364 (M+F) AMENDMENT 2

TSS Training • Vessels under 20 metres

Training vessel: Watch One • 14.2 m • power-driven. This beginner module is written for recreational vessels under 20 m. Rule 10(j) therefore applies throughout: do not impede the safe passage of a power-driven vessel following a traffic lane. Learn the geometry first, then apply it under traffic pressure. The locked collision engine remains untouched.

HEADING, NOT COG

Correct crossing with tidal set

The vessel's heading is as nearly as practicable at right angles to traffic flow. Tide may visibly skew the track/course over ground.

COMMON ERROR

Incorrect diagonal heading

A deliberately diagonal heading makes the crossing intention less clear and does not satisfy the right-angle-heading requirement merely because the vessel eventually reaches the other side.

JOIN / LEAVE

Do not confuse crossing with joining

When joining or leaving a lane from the side, do so at as small an angle to the general direction of traffic flow as practicable. This is different from crossing, where the heading should be as nearly as practicable at right angles to traffic flow.

RULE 10 • VISUAL GEOMETRY TRAINER

Bridge-display TSS crossing

Compare the geometry visually. Green ticks identify correct Rule 10 geometry; red crosses identify deliberately incorrect training examples.

✓ CORRECT — right-angle crossing heading
Heading and track coincide: the vessel crosses the traffic flow at right angles.

TSS training for the small recreational vessel.

You are in command of Watch One, a 14.2 m power-driven vessel. Every lesson is taught from the under-20-metre viewpoint: plan early, avoid impeding lane traffic, use the ITZ where Rule 10(d) permits, and if obliged to cross, use the correct Rule 10(c) heading.

Assessment basis: International Regulations for Preventing Collisions at Sea (COLREGs), current MCA Master (Code vessels <200 GT) / OOW (Yachts <500 GT) oral syllabus, current MCA Small Ships Navigation and Radar assessment criteria, and current MCA examination structure. Project Watch questions are independently written and do not reproduce RYA or MCA examination questions.

PROJECT WATCH • IALA REGION A • FULL MOCK

Buoyage & Marks Examination

This full assessment covers every mark taught by Project Watch: identification by day, light/rhythm by night, meaning and the correct passage decision. Questions are original to Project Watch and use the same buoy data and vector artwork as the training module.

Full Buoyage Mock Every one of the 12 Project Watch marks is examined three ways: identify it, recognise its light or daytime appearance, and make the correct navigation/passage decision.
Assessment basis: The exact IALA Region A buoyage set already taught in Project Watch. The exam uses the same BUOY_DATA and BUOY_TRAINING information as the tutorial so the learning material and assessment remain consistent.
BEGINNER COURSE • IALA REGION A

Learn every mark one at a time.

Start with the daytime appearance, then learn the light, what the mark means and—where the buoyage system actually specifies one—the side on which to pass.

Scenario facts established before the exercise Two power-driven vessels, in sight of one another, on unaltered crossing tracks that intersect. At handover the target is on Watch One's starboard side.
Rule 15 — crossing situation In this constructed encounter, Watch One is the vessel that has the other power-driven vessel on her starboard side and is therefore the vessel required to keep out of the way. Where circumstances admit, she should avoid crossing ahead.
Rule 16 — give-way vessel The give-way vessel must take early and substantial action to keep well clear.
Rule 8 — avoiding action Avoiding action must be assessed in the circumstances of the encounter; Project Watch does not treat one fixed helm order or one universal CPA as automatically correct.

Source baseline: IMO Collision Regulations Convention (COLREGS), current 2026 publication/overview. This prototype uses rule summaries, not a substitute for the official publication.

3. Your watch

The 1–5 score is a provisional simulator training score, not a legal finding or professional COLREGS certification. In this build, all simulator warnings are intentionally inhibited outside 0.50 NM. It uses collision outcome, closest approach, timing and manoeuvre-quality flags. The thresholds are training parameters, not statutory COLREG limits, and remain subject to maritime review.
