The bottom is referred to as the sill. The end frame is the action part of the trailer. The rest of the trailer is made up of the box that sits on the chassis, and includes the floor and running gear (wheels, brakes, lights, etc.). Lockrods come in different lengths and thickness (rod diameter) depending on intended use.
The boat has a draft of 4.90 ft (1.49 m) with the standard keel. It can be transported on land on a towed double-axle boat trailer. [1] [2] [5] For sailing downwind the design may be equipped with an asymmetrical spinnaker of 700 sq ft (65 m 2). It will plane under spinnaker. [1] [2] [5] The design has a hull speed of 6.29 kn (11.65 km/h). [2]
The sail area-displacement ratio (SA/D) is a calculation used to express how much sail a boat carries relative to its weight. [1]/ = [() /] = () In the first equation, the denominator in pounds is divided by 64 to convert it to cubic feet (because 1 cubic foot of salt water weights 64 pounds).

Boat prices vary depending on the model, make, size, features and condition. For instance, an 18- to 25-foot used pontoon can cost between $8,000 and $12,000 .
A body in water which is stationary with respect to water, experiences only hydrostatic pressure. Hydrostatic pressure always acts to oppose the weight of the body. The total (upward) force due to this buoyancy is equal to the (downward) weight of the displaced water. If the body is in motion, then there are also hydrodynamic pressures that act ...
A trunk engine locates the connecting rod within a large-diameter hollow piston. This "trunk" carries almost no load. The interior of the trunk is open to outside air, and is wide enough to accommodate the side-to-side motion of the connecting rod, which links a gudgeon pin at the piston head to an outside crankshaft.
