Mandating the wearing of seatbelts isn’t entirely about protecting the person wearing the seatbelt. An unbelted occupant becomes a projectile in a sufficiently violent collision, and that projectile can cause harm to people outside of the vehicle.

Heck, I recently saw a video (may be an old one) of a driver who fell out of his car while showing off his acceleration. Now the entire car is an uncontrolled projectile.

Interesting that pleasure craft have dead-man switches you can optionally affix. They’re also designed to turn anti-clockwise forever if nobody is at the wheel.

I guess because there aren’t seatbelts and these boats are usually open-top.

Isn't this dangerous to the person falling off (assuming no dead-man switch)? You fall off only to be run over by your own craft one turn later... It does mean that the boat won't run away far though, so there's that.

> pleasure craft... turn anti-clockwise forever if nobody is at the wheel.

That's probably a result of the "paddle wheel" effect of the propellor rotating through the water: a bug not a feature.

Or harm to other people inside the vehicle.
