A sailing vessel operator when approaching a pwc head on should slow down and change course.
When approaching a sailing vessel head on, it is up to the motorboat to yield. The motorboat operator should swing wide as early as possible to stay well clear of the sailing vessel.
A visible white light on another vessel indicates that it is approaching you head-on. This means you should also exhibit a white light to signify that your vessel is also approaching head-on.
If you see a vessel displaying only a white light, it indicates that the vessel is a power-driven vessel. This vessel is approaching you head-on or is overtaking you. In both cases, you should be prepared to take action to avoid a collision.
A sailing vessel operator should sound a blast on the horn when approaching a PWC head on. However, it is up to the operator of the motorized craft, in this case the PWC, to take evasive action.
The sailboat operator is the stand-on vessel so they should keep their course and speed while the PWC is the give-away vessel so it should change course and speed.
