We were motoring down the Pacific coast of El Salvidore about 8 miles offshore and about 2am ran through a fleet of about 30 fishing canoes. No lights and small. They didn't show up on radar till they were 1/2 mile away and only some of them. We had to weave through them with a spotlight at 2 knots.
They fish offshore usually with some of them lit but this time none had any light at all. If there was a light it must have been a candle.
