Summer Bikini Beach Girls Recreate On Yacht Vessels

Motor yachts typically have one or two internal combustion engines that burn diesel fuel. Depending on engine size, fuel costs may make motor yachts more expensive to operate than sailing yachts. Biodiesel for marine propulsion is in the experimental stage (e.g. Earthrace).
