My family has a lake house in Deep Creek, Maryland that we've had since 1987. We've got a 1988 Wellcraft 190 Classic and a 19 foot Flying Scot sailboat. If I want some real speed, I just go to my neighbor's and borrow either his 1996 Malibu skiboat or his Kawasaki jetski.   
Wellcraft (isn't mine, but very close.)
