: Hello All First time Poster from Alaska. Long time Wood boat
: appreciator, first time builder. I know my way around a machine
: shop and am pretty handy with a welder and either steel or
: aluminum but am an admitted wood butcher. Long story short, my
: young son, My Bro in law and myself are constructing 3 Yost sea
: tour 15 EXP's Wood frame non folder). I have a couple of general
: questions concerning the layout phase of construction. First on
: the most excellent web site where these plans reside there are
: build examples of the Sea Bee and some other designs, but there
: difference in the way the keel is handled between the two types.
: In particular I am wondering if I need to fully inlet the keel (
: ala the nikumi multi chine, which I think is correct as the
: EXP's are multi chine) or if it is only partially inlet as in
: the cross section portion of the Sea Bee build. Secondly some of
: you that have completed Wood non folders of this design, how
: does one go about setting the cross section ( bulkheads/ frames
: if you prefer) on the stations. Once the frame is cut to shape I
: have lost the reference point to Base line, and am left
: measuring the depth of the keel slot plus the height above base
: line plus the height of the station which while workable seems
: some how wrong to this metals based machine type person. I am
: used to having some Datum point. Just wondering if there is an
: easier or more elegant solution ?

: Any help comment flames whatever are appreciated,
: Thanks

Hi Dan,
I think I understand some of your questions. So here goes.
You asked how deep to inset the keel. I make mine 3/4" deep from the keel point. I have done this on the Nikumi I have built and the Sea Tour 15.
I didn't understand the bulkhead question as there are no bulkheads in the design. However I think you may be referring to the station forms. Are you laying out the forms? The offsets that are provided on the Yost site are measured from the horizontal and vertical baselines. Once the station is cut out I don't normally refer back to the base line. When you attach the forms to the strong back only the first and last stations are attached. The others are held in place by the stringers sorta like floating above the strong back. The spacing of the stations along the length is important to get the shape the designer intended.
I hope I didn't confuse the question and this helps some what.
Good luck with your build.
