Sailing revision resources
Build the knowledge you need before you're asked for it.
StandOn resources are designed to help sailors understand and recall essential knowledge — from COLREGs and navigation lights to day shapes, sound signals, buoyage and qualification-related revision.
We're building this library around the same principle as StandOn itself: focused learning, active recall and clear explanations that support proper training and practical experience.
Revision by qualification
Day Skipper
Focused revision for the knowledge used throughout Day Skipper theory and practical training, organised so you can strengthen individual topics without trying to relearn everything at once.
Revision by topic
- COLREGs
- Understanding and recalling the collision regulations, vessel responsibilities and common encounter situations.
- Navigation lights
- Recognising vessel status and aspect from the lights displayed at night.
- Day shapes
- Identifying the shapes vessels display by day and what they communicate.
- Sound signals
- Understanding manoeuvring, warning and restricted-visibility signals.
- Buoyage
- Recognising buoyage marks, characteristics and the information they convey.
A better way to revise
Reading something once is not the same as being able to recall it when you need it.
StandOn is built around active recall: retrieving knowledge from memory repeatedly so weak areas become visible and important information becomes easier to recall.
Our public resources help explain the knowledge. The StandOn app gives you a structured way to practise recalling it.
Built to support proper training
StandOn is a revision and knowledge-retention tool. It complements professional instruction, recognised course material and practical experience; it does not replace them.
Where qualification scope, regulations or technical sailing knowledge are discussed, our resources are developed under StandOn's editorial and review standards.
