Some people and new boat owners don't know the differences between a small "ocean pleasure boat" and a lake or river small pleasure boat to be used the same way
As well as how to operate them in all conditions.
I bought a used 21 ft. IMP Aztec V day cruiser inboard/outdrive ocean boat, it had right at 4 ft. gunnels (sidewalls) and a big V on the bow to push water away when hitting big waves. I bought it when my kids were younger so they couldn't fall over the sides when moving in the water, taught them to water ski and sold it when they grew up and moved out.
My wife and I both took a U.S. Coast Guard boat safety course for small boat owners before using it
