Experience
Since most of us don't have deep pockets, start with the bottom this spring, ie keel, smooth hull, folding or feathering prop. you will see a difference in 2000 and your crew & you will learn the boat. Then the following year go for the sails. Like Cliff said the sails are your engine. If you were drag racing you would want a 455 stuffed into a VW. Then start tweeking with backstay, ball bearing jib cars, more powerfull hard vang, etc. Our 1st year we raced the boat as we bought it, was disappointed but realized the winners had already done their homework and work. Its taken us a few years but we usually pull bullets in the offshore races, and are holding our own in the can races.Good luck PJ
