My preference is to build 'Banks dory-style', which is 'right-side up', as shown in Gardner's book on dories. The other way is 'Swampcott-style', which is 'bottom up'. Either method can be used for most boats whether they are built POF, clinker, carvel, or S&G. It just depends on which parts of the job you prefer to make easier for yourself.
Beginning to take shape is a 7'6”, flat-bottomed, double-chined, lapstrake skiff. I used a female mold to determine rocker and a mid-frame to control plank spread. Once both planks are positioned and glued, I'll add the frames, 'wales, and risers, etc. and then turn the hull over to complete the bottom work.
Hopefully, I'll be doing the river trial by Xmas, because I need to start a boat suitable for a
Rivers West event this Spring, which is rowing to Sand Island as the "shake down" for a longer row later in the summer to Astoria.
