Hull cleaning is one of the most important preventative maintenance services you can do to extend the life of your boat. This service will provide you with both better fuel efficiency on the water and faster speeds. However, this should only be done by an experienced diver. Our hull cleaning service at Jack's Diving is done properly to avoid any possible damage to the finish or protective coating of your boat. A poor cleaning job will actually do more harm than good. When having your boat's underside inspected, make sure to contact the professionals at Jack's Diving!
