Confirm comments by Hobie1616. West Maui is not a place to have people sail without good supervision. Rented a wind surfer years ago, and was lucky to have a jet ski get me back to shore, when I was trapped by an offshore breeze, and in trouble. The local rental at the resort did not help, as I was not on one of their board. Last year a guy with kayak rental was going to have cat rentals at "Prindle Beach" but could not get a permit to expand his program to catamarans. Similar problems all over Maui. Not enough business to have adequate support, and weather can come up quickly. kayak and standup boards do a good business, and can be controlled.
