Spiling in lapstrakes would be hitech for me. There'ld be these long triangular spaces behind the wood that could collect moisture, I would think, unless they were filled with something.

You're saying, then, that the 1/4" wood was glued right to the hull?
And it might have been cedar or fir or mahogany?

What is more usual is that you glue in vertucal ribs of, say, oak - 1/2 by 3/4 would be the tightest dimension I can imagine. Then you fill the between spaces with insulation. Then you carvel in the liner using screws and donut washers. Hi-tone And Hi-tech!

What is this boat here, a grand piano???

Was thinking more like: Cut, Paste, and Run. ...............or sail
