... the collision occurred at night between an outboard-powered 20’ fiberglass boat and a 47’ commercial outboard-powered boat as the boats closed in on each other at 24 knots. Lights from an industrial plant on the shore made the navigation lights of the 47’ boat very difficult to distinguish, as well as the searchlight shining forward from the 47 footer which further obscured the lights. The skipper of the 20’ boat was operating on the right-hand side of the channel, and the 47’ skipper was on the incorrect (left-hand) side of the channel when they saw each other. The skipper of the 20’ boat turned to the right but did not slow down, while the skipper of the 47’ boat turned to the left and slowed down.
