There is no definitive book on halibut schooners. It's hard to define a "type" there is so much variation. Some are transom sterned, but others like the one I've carved are canoe sterned. All had moderate deadrise ( not flat bottomed), and tended to be plumb stemmed, but not always. See the problem?
