Dan:

34 prospects listed on crew rooster at 170# average? That's a good indicator of some form of limiter restraining crew weight under the 176# mean average. I have a whole list of crew choices that weigh more and I'd like to get them on the boat.

: 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.
::
:: Dan
::
:: :: 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
