Carolina CC, jig or plank-on-frame

Hi,
I am currently trying to decide between attempting to build a jig boat or plank on frame.
-Does anybody have any ballpark #'s on how much a 24 ft boat weigh and what would be the power rating for either type?
-One other (dumb) question, what kind of stock is used for the frames and how are they cut, particularly the curved pieces? I understand that with a jig boat, the jig is cut on a NC router. Is the same done with the heavier frames in a plank-on-frame boat? It seems the frames are typically covered w/strips of cedar then a layer of ply, then epoxy/cloth.
-which is easier to build?
thanks to any who reply

 

boat building process??

carolina plank on frame boats are made laying out the keel and placing the ribs by eye, I imagine by now you could probably get someone to CNC the ribs for you as they are used the same one a jig is used on a cold molded boat. A cold mold boat is done upside down using plywood or similar material as the jig typically cut on a CNC. I am currently building a 29' I bought already under progress and have owned a larger cold molded boat for years. Cold mold seems to be lighter and does not have the print thru issues as a plank on frame. Stringers are typically made of douglas fir, juniper mahogany. nobiggie really as it gets encapsulated anyway. Easier to build I would say would be coldmold if you have to lay out the lines yourself, if you go over to sportfishermandotcom under rebuilds you will see a sullivan plank on frame in progress and you will see the layout by eye method, he does a great job but laying it all out has been what he has done for years
