These small escort carriers were pretty basic, and not much to look at. I don't know if the above link has more detailed plans, but they are better than nothing I suppose! Basically, they were just merchant ship hulls with a flight deck on top and not much else.
My first ship was the old escort carrier HMS Premier after she had been converted back to a merchant ship (Rhodesia Star) after the war.
