Although I don’t do a whole lot of dinghy sailing but the times I have done it, it has happened to me more than once. No being completely run down by a power boat but have come across power boaters who have no regard for right-of-ways when it comes to small sailboats.
I was sailing a Capri 13 out of Santa Barbara harbor one day and was basically on collision course with a powerboat coming out of the harbor.This guy could clearly see me but he had no intention of altering his course. I had to gybe in the last minute just so he wouldn’t run me over.
It was not an honest mistake and he wasn’t even the least bit sorry about what he did. I know that because as he past me going at about 20 knots while churning up a 3 foot wake, he looked at me and threw up his arms like it was my fault for getting in his way.
