Same experience, but in the Broads, twice while headed from Alton to Center Harbor. No other boats around, but two clowns found it necessary to come up from behind and pass within 50 feet with me going 30+ MPH. I drop off plane to comply with the law, slosh through their wake, and shrug at how -- even the open water -- the boneheads still manage to make their presence known.
Perhaps Marlee et al. got tired of waiting for us to move over...
