New guy needs help (lofting for boats or sails)

I'm new to this site and just finding my way 'round.
1. Have a copy of C.A.Marchaj "Aero-Hydrodynamics of Sailing" would like to sell, p'bly on Ebay. Pricing?
2. Have a design from an old woodworking magazine for a plywood dory. Article states that any experienced builder can construct the boat from the tables of offsets and end deminsions shown inhe article. HELP. I do not understand lofting for boats or sails but I do have a 2-dimensional design background.

 

I believe this link is correct. Its a very well written book on boat construction and covers lofting. Worthwhile printing it out.

Thanks. I'll check it. Any thoughts on Marchaj book price?

 

AbeBooks is useful to buy or price hard to find books. AbeBooks has 5 used copies of Aero-Hydrodynamics of Sailing at $44, $54, $85, $168 and $179. http://www.abebooks.com/products/isbn/9780396077398/4368807487

 

The Marchaj book is a good reference, you may want to keep it. I've seen them at swap meets and boat shows for under $20.

The dory design did say and "experienced builder", which means you should consider a different set of plans, preferably one with a set of building instructions and possably a living designer you can call and ask questions. Dory designs are everywhere and not very costly. Free plans often provide precisely what you've paid for them.
