:: :: I beleive that the helmsman does not contribute to the

:: :: If you calculate the torque generated by an object at
:: :: the center of mass of the helsman facing inboard at the
:: :: narrowest part of the boat and compare it to the torque
:: :: generated by an object located at the center of mass of
:: :: a crew member facing ourward at the widest part of the
:: :: boat, the helmsman is half as efficient at righting the
:: :: boat (counteracting the heal) than the crew. Therefore
:: :: he/she should only count as half in computing the total
:: :: weight limit for the boat.
:: ::
:: :: crew+crew+crew+crew+skipper/2 = 880 pounds
::
:: Seems reasonable, but the logic would lead to not
:: allowing ANY helm changes during a race. Not
:: unreasonable for buoys, but potentially problematic for
:: longer stuff.
::
:: The second you can take that skipper off the helm at
:: all, you have a potential significant advantage, with no
:: way for monitoring.
