Especially this one, as it would probably require me to shed about 25 lbs of aforementioned keister to be small enough to crew for some of you dudes.

Looks like the ideal weight for the front part of the boat is 155 lbs since the drivers are all 175+ it would seem...

The rest of the classes would only involve transfer of said keister (which is a monumental task in itself - not sure how you get all that free time like a certain Mr. Mom with the Capricorn)
