He also appeared on the show as Harris, a dim-witted animal control employee. Wittels also wrote for the programs Secret Girlfriend and Eastbound and Down. In 2012, Wittels was cast as a co-star in Sarah Silverman's NBC pilot Susan 313 along with June Diane Raphael and Tig Notaro, which was not picked up.
Boat Displacement and Sail Area. Boat displacement is defined as the volume of water displaced by a boat afloat, and sail area is the total area of the boat's working sails.
So a displacement boats theoretical hull speed is when the wave length is equal to the waterline length. The important thing here is the length of the wave is relative to the length of the boat. The SL Ratio is a simple formula for calculating displacement hull speed which is typically 1.34. 1  Velocity = (g * Length / 2 pi) ^ Â½.  g = acceleration of gravity (32.15 ft/sec ^2)
