I can see it, not only from a health related issue, but mainly there are a lot of people operating water craft that should not.In TX that rule went into effect a year or two ago. It is supposed to be attached to your person while above displacement speed but I've not heard or seen anybody get stopped just because they weren't, but I'm sure if there is another reason to stop you they will look for it...
That little guy is capable of about 21 mph, (kind of a spooky ride), however I run it about 12 mph, in areas like this.Some of these smaller boats (like in the above pic) go so fast that you can get tossed out. My old boat, a Sig 290 the sides were so high at 26 knots hitting a good wave got rough. But no way was I going over board. Being 5'5", I could just about see over the windshield forward and the side come up to a little less than my shoulders.
If you used a cut off switch and wore a vest, you would not need the rope (line) and eliminate the chance of hanging yourself. LOLAs I aged. I realized that any way I could be out of the boat could be death. If alone and the wind was blowing the boat away from me. engine stops in gear. But there is no way a fully clothed person can catch up to a Chap in a breeze. So i have a strong rope tied to a bow cleat. Driver side . & enough line so that if I fall in . The rope will stop me & my feet before the prop gets me. Before heart surgery.
I did almost pass out. I fell overboard & recovered fast enough to climb back in the 16' Aluminum fish boat. I would have drowned without the rope attached. Macho man was not wearing his life vest.
