: The 215 (265# for the "L"} is the weight in good ol' pounds of the
: water displaced by the craft when she's "sitting on her lines."
: Each of these yaks has a design waterline. When loaded to to their
: designed displacement they should float at this waterline. You're correct
: in assuming that the load includes the weight of the yak. You can exceed
: the designed displacement to some extent without compromising performance,
: but there comes a point where increased drag and decreased freeboard
: become a problem. You could probably use the standard design for light
: camping, but for anything extensive you would bump up against your cargo
: limits.

: As a guy who is comfortable in a XX t-shirt and having a high center of
: gravity, which makes me very popular on the high side of a sailboat, I've
: been looking at the "L". Nick say's all the the L's dimensions
: have been increased by about 6%. Well, yes and no.
: ---------------------Guillemot-----------------Guillemot "L"
: Length.....................17'.............................18'
: Beam....................20.75".........................23"
: Ht. @ Cockpit........11.75.........................13"
: Design Disp..........215#.......................265#

: But if you study the sections You'll note that there isn't much more fullness
: below the DWL in the aft four sections of the L compared to the standard.
: The increase is more dramatic from there forward and some of this increase
: is carried right up to form 2. So it appears that Nick has placed the new
: hull displacement with a forward bias 'cause that's where he expects most
: of the additional weight to end up. So Nick is understating the work and
: thought that went into this enlargement. He didn't merely scale up the
: dimensions and let it go at that. For all of me the "L" looks
: like the weigh :-) to go.

thanks george;
can we sand it down a little finer?
by your estimate how much can i weight down the G-S before it becomes dangerous?
i've already lofted the forms for the G-S from nicks book and if i need to build the G-L i will have to buy the plans. not that i begrudge nick his $'s, i just think that lofting is part of the process of building a boat. i've only built three boats but that is my opinion. by the buy, i would pay for an accurate table of offsets. gladly! (i don't want to start another food-fight!)
