I've a few close calls of this sort over the years. Never had another boat hit me, but close enough near-misses to worry.
At least the anchored boat in the vid could see him coming. Two seasons ago we were drifting with the fleet offshore, in a substantial early morning fog - everyone with running lights on, most with their engines idling, all observing "social distancing," as we knew it back then. And off in the distance we could hear a good-sized boat running hard, West to East, getting closer and closer.
Started to freak, as the conditions called for very careful, slow-speed operation. The other boat kept closing the distance, and we could hear its rather loud inboard engines, so we knew it was a good-sized vessel. We reeled up and I manned the helm - just in time to see a 35' Tiara come flying by like a freight train, no more than 30' off my transom, running at least 20 knots - on full plane. He disappeared into the fog as quickly as he had appeared. Jesus, God, I was completely skitzed out. My knees were weak for an hour afterwards.
There are a few such boats that are regulars out there, but it all happened so fast that I never caught the name on the transom. Much more concerned with not ending up swimming in 80' of water. Or worse. Much worse.
I just don't understand people like that. Is catching a few dopey fluke THAT important to such people that rushing around in a very heavy fog is called for?
Anyway, it was a good lesson in "Defensive Boating," as one can not blindly trust that everyone's brain is wired correctly.
