Revision.

The collision regulations require that skipper keep a watch at all times and by all available means. Radar, sight and sound.
Looking behind large sails, reduce the size of headsails in crowded areas.
Listen for sound signals. Listen on the VHF for shipping movements.
Listen for engine noises.
Take a series of bearings of an approaching vessel. A constant bearing shows risk of collision exists.

It is the responsibility of  all skippers to avoid a collision.
