A bimini top would likely be made of the same material as a dodger and stands aft of the cockpit, above the helmsman, but does not provide protection from forwarding waves. If someone tells you to "check the bilge, " they ask you to verify (you may have to lift a floorboard in the main salon) that there is little or no water collected, which can weigh a boat down and thus increase drag. When sailing (particularly racing), someone yelling, "Get to windward! " A fender may be tied to rails, lifelines, or cleats aboard a vessel. Some terms to know as you help float plan: A float plan is a document detailing the intended agenda for the boat, including vessel, crew, and equipment information, date of departure, date(s) of arrival, fuel stops, overnights, and dockage/anchorage reservations.
