It's difficult/impossible to compare specs from one mfgr to another. Even if there's no rocker, they should say rocker = 0, etc. Somewhere on some forum i read that Swift changed the winisk specs at one point. True or not i don't know. The scales are tipped to the freedom 17 right now. check back next week, it might change.

I'm often amazed at how little information mfgs give about their boats.

Folks over at solotripping.com would be able to give you a lot of this missing info.  Some builders and hobbyists who love to geek-out on the subtle differences an inch can make.
