Hi kevin-
here is a link with the pics of the stringers. At the time I was not intending to make stringers but just some floor support were I tore out the splash well and added floor area to my seacraft. Bobby Wartman took it one step further and then Wilson Ayala took it even further then that by building an entire stringer grid sysyem for his boat. I suggest you look up their posts on ClassicMako. There is also a gentleman who redid an 23 formula that used this method. You can do a search on google for his site. I'll see if I can find it and post it later.
