Subject: Weight Limit
Info: (22378 views) Posted: Tuesday 8-25-09 06:41:38 PM
Hey Guys, Sorry to have issed the meeting and the whole sailing season. I have been facing some physical challenges. Now that the end is near, I see that my next big hurdle is the weight liimit. I will have a stainless steel hip implant to add to my weight making it iven harder for me to make weight for Strega.

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

That is my best estimate of what is fair. And no Jason, I will never weigh 190 no matter how much I diet.

Larry
