Boats, jet skis, motorcycles....combine inexperience of operation and lack of common sense..bad things happen. If you don't own one or use one on a regular basis, probably a good idea to not rent one on vacation..
Throw in alcohol and ganja and it gets real messy. I’ve riden motorcycles all my life. I used to rent them In the 80’s - 90’s in Negril. Then I smartened up, thankfully before anyone was hurt.
