Are we not missing a glass component in carvel vs strip?
That is, how much glass, and outside only gives me pause.
"Strip planked" is a term that covers a wide spectrum of builds that use different engineering aproaches. That's because it only describes one aspect, planking made from a lot of individual strips. It's also older then a lot of people think, it was invented at the beginning of the 20th century to utilize the cheap offcuts from making dimensional lumber. Back then the strips were beveled and only nailed to each other, maybe with some paint in between. Later this evolved to glued and nailed, then only glued, the frame spacing was increased to match the new strength of the planking and lastly fiberglass was added first outside for superior waterproofing, then also inside turning the overall construction into a cored fiberglass build. There's also glueing veneers over the strips method, wich rightly belongs in the cold molded definition.
With a boat that was designed for carvel the simplest thing is to maintain the original scantlings and just use square strips instead of wide planks. The result will be a stronger boat (even if the strips are only nailed wich nobody does anymore), but it will sit on her lines and no additional engineering is required. Any outside glass is just for additional waterproofing, it doesn't actually matter how much you use. With all the epoxy even light glass survives without apreciable print trough.
The downside is that you use more wood then actually necessary since some of the plank thickness and framing is redundant.
You can of course redesign the scantlings to use the superior strength of a glued skin, or even to transform it into a cored fiberglass boat. This will result in a lighter boat, so you either add ballast or redraw the immersed part, etc.
The question is simple, you can use a little more wood, or you can pay the NA to redo the plans.
