Navigation lights trainer
ASA 101 sailing is usually taught in daylight, but the test still expects the basic light picture. Drill what red, green, and white tell you before night or fog makes the answer matter.
Night watch simulator
Make the watch-standing call from light pictures, bearing trend, fog/restricted-visibility cues, sound signals, and anchor-light confusion. Saved misses feed the weak-area coach.

Light rules this drill reinforces
- Red marks the vessel's port side. Green marks starboard.
- White sternlight is seen from aft. A white all-round light is commonly used for anchoring or small power configurations depending on vessel type.
- A sailing vessel underway shows sidelights and a sternlight, or an allowed combined lantern on smaller vessels.
- If a sailboat is using its engine in gear, it is power-driven under the rules.
- Required lights apply from sunset to sunrise and in restricted visibility.
