: Thank you, and yes, the "bulkhead" I am referring to are
: the "cross sections" in the Yost instructions, or they
: could be called frames. Anyway yes I know that only the first
: and last are attached to the strongback. However the Baseline is
: NOT the surface of the strong back it is also no longer present
: on the cross section. My question then is how do you go about
: getting the two attached at the correct height on the stations?
: Also as to the keel layout thing, For the Sea Bee on the Yost
: page on cross section layout and construction the keel is
: actually half above the offset point and half below in his
: example ( IE the mark he makes in the ply wood representing the
: keel offset is the center point of the keel beam so in essence
: the keel is half inch lower than the offset marks ) ... on the
: multi chine example the bottom of the keel is actually ON the
: off set point. Since neither example IS the Sea Tour I have to
: pick one, just curious what most people did.

I'm just starting a Sea Tour 13, also my first build, and I've been wondering about the same thing so I look forward to the discussion. Here's what I've been planning to do. The strong back is not the baseline, but it could be used as a reference (I think). On the ST 13 the HAB of the keel, of the first section is .032'. So why not say the base line is 6" (0.5') above the strong back and mount that section so the keel is 0.532' above the strong back? In this example the 4th section would be mounted with the keel 0.527' above the strong back. Then the "floating" sections and the stem and stern can be pulled down towards the strong back or pushed up from it until they are at the keel offset plus 6" from the strong back. Or maybe that is all wrong! BTW, there was a good thread recently about establishing reference points off the strong back, to check the frame for twist.

Thanks for asking the question,
Will
