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
Dan
