Norcalsailing report featuring Summer Palace:
http://www.norcalsailing.com/entries/2012/06/05/ditchrun2.html#.T-iWoI2Mfqs Below quoted from Pressure Drop: Drew Scott was helming a F-28. "My crew is starting to swing around to pick me up when El Raton, in perfect control slides up beside me and asks if I would like to get picked up. They had already doused their chute and stopped beside me. I took their offer and got back into a boat (trying to stop a lightweight trimaran next to someone when it is blowing in the mid-20s is not easy so I figured I would not turn down El Raton. My crew ably finished the race on Papillon, only one boat behind El Raton! And I had many adventures with El Raton, but that is their story to tell. So, a great big thank you to the Ray Lotto and the crew of El Raton for pulling my soggy hide out of Suisun Bay!! Drew Scott Papillon (most of the time)" |

:: :: 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.
::
:: Just thinking out loud ....
