Renters Beware! For several years I happily rented powerboats from Ocean Runner in Cruz Bay. I must sadly report that my June 2010 will be my last. The boats, motors and service are all in poor condition. I highly recommend that you seek other options. In addition to feeling cheated, I question the safety and reliability of their aging craft.
Next time I highly recommend you look into Wet Woody's for 6 or less people. We had 7 in our party and their current license is capped at 6 passengers. I know these guys and they can be trusted! http://www.wetwoodysvi.com/
