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 proposed a reasonable plan some time ago and I want to write it down again. This is sophomore physics at its best!
I beleive that the helmsman does not contribute to the righting moment of the boat in any significant way. We sit facing inboard and may not hike past the sheerline of the boat.
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
That is my best estimate of what is fair. And no Jason, I will never weigh 190 no matter how much I diet.
