I would like to know if anyone can recommend a starting point for learning sailing yacht design. My goal is to design and build an 18m (60ft)(max) wooden yacht for circumnavigation and high latitude sailing/cruising. My desire is something akin to a Danish Seiner (with pilot house.)

I have read some basic nav arch books, including SNAME's "Principals of Naval Architecture" but they were all geared to ship design. I also borrowed and read Neilsen's "Wooden Boat Designs" to get some ideas on shape and proportions. I am stuck though as to where to start. Any suggestions?
