Mike,

FYI, there are currently 34 people listed on the e27 crew list page and the average weight of these people is 170.1 pounds.

:: Thanks for figuring this out Larry. I like your formula
:: because its based on math and not in speculation.
::
:: Anything we can do as a fleet to build participation
:: makes sense.
::
:: Raising the weight limit using this mid ground method
:: which no one said no to through informal polling at the
:: fleet meeting, meets the aim of opening up the fleet to
:: current owners and a whole slew of crew the 880 maximum
:: prohibits. Those are crew choices above the 176 # mean
:: average. Growing infinitely more dificult to place as
:: crew on e27s when known prospects start to weight ove
:: 200#s.
::
:: Mike
::
:: :: 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
