Oh boy!!
I have stayed out of this thread as long as I could, in the hope it would peter out. But it hasn't.
Taid's Inn is a 32-foot semi-displacement Chesepeake Bay fishing hull. She displaces a little over 9 tons. At idle, she runs about 3 knots, and puts out a ripple. At 1,200 rpm (about 8 knots) she leaves a wash of about 9 inches. At cruise (about 2,600 rpm and 14 knots) she puts out a wash of about 2 feet. I have yet to run her wide open.
The wash is relatively smooth and well spaced, so the PWC crowd love to jump her wake. In between those speeds, the wash grows steadily, but unless I throttle up to maximum from idle (thereby digging a hole in the water), it is virtually impossible to generate the kind of wash the Tupperware running shoes put out at anything between deqad idle and a full plane, and even then the wash subsides quickly once she settles back down.
Wash is a function of hull shape, displacement and speed, folks. It can be controlled, but let's face it, that requires the skipper to control the inputs. My experience, although not as extensive as some of you, is that some people are blissfully unaware of the havoc they cause by running at partial throttle, or how to reduce the wash they create. The Collision Regulations require skippers to maintain a constant lookout, and makes them responsible for any damage caused by the wash from their vessels.
Rather than beat this thread to death, with no viable probability of reaching a solution, the logical way to reduce careless operation os to educate people, and to advocate and encourage regular and active enforcement of the Coll Regs. Little things, like looking behind you when underway, seem to be omitted from the 30 minute training provided when a boat is sold, so the solution lies with the need for proper training before the new owner is allowed to take the wheel. Operator licensing based on successful completion of a formal training program may look like a tax grab to some people, but it is the only way to reuce the stupidity we all see when underway.
