When I first got my boat I sailed through the Race where there were a bunch of guys in small boats fishing. I assumed that they were NOT anchored, but drifting and casting their lines... I and sailed right through them and snagged one guys anchor line which we had to cut. Ruined his day of fishing. I was embarrassed. I got his name and addy and sent him money for new ground tackle. Who would anchor in the race near Race Point? he did! Live and learn.
