Hi Jerry,
We were at Jack Tar Playa Dorada in December and did not see any motorized watersports. A little further down the beach I saw a parasailer so maybe they have some jetskis down there. The water was pretty rough when we were there so maybe they just had them put away.. Beware of the vacation salesmen at Jack Tar,they will tell you they are with public relations and ask you if you got your free present, then you will be taken to an office where they will try to sell you their vacation plans. Not high pressure but when I said I was not interested I did not get my free shirt either. Other than that we had a great time, everyone else was friendly and the grounds are really nice. Have A Nice Trip
