That's nothing, there was a ten foot three point hydroplane on Spirt
Lake Iowa, back in the fifties. Had an eighteen horse motor.

My brother and I had a homebuilt 3 point hydro in the early 60s. It
was 8 ft long and scary fast with an old Merc 7 1/2 on it. Control
was a big issue and it required a bit of body english to get it
turning properly. Freeboard was just about non-existent, with a 1 ft
wake enough to submarine it.

In Norwalk Harbor there were always a bunch of home made little
hydro's. They used to have plans in the back of magazines that told
how to make one using two sheets of plywood. It didn't take much power
to make them fly. Lots of kids built them in woodshop class.
