Race signals and race-day skills

Review official flags, starting routines, line bias, shifts, laylines, marks and gates. Pair the lessons with regatta management and race timing.

Trim and performance

Revisit sail controls, telltales and changing gears for dinghies and keelboats. Use track replay and analysis to connect a practice session with what you are learning.

COLREG basics

Study common collision-avoidance situations, lights, channels and sound signals through illustrated explanations.

VHF procedures

Prepare for common radio-call situations with example call scripts that you can review before departure.

First aid on board

Review onboard emergency references and common first-aid situations as part of your crew's preparation.

Weather navigation

Revisit weather fundamentals and practical preparation alongside the marine forecast.

Illustrations and short knowledge checks

Built-in SVG diagrams and illustrated lessons are available offline. Short knowledge checks, common mistakes and practical actions help you review a topic in a few minutes. Links to external official documents require a connection.

Before a start, revisit a right-of-way example. During crew preparation, review a VHF script together. After training, open the trim guide and compare your notes with your recorded sailing track.
