I just did mine and went with 3/4 marine ply on the outer layer with 3/4 Coosa Bluewater 26 on the inner. I would have gone all Coosa but plan on adding trim tabs and wanted to have wood for the screws to bite into. I did go kinda high end on the plywood using Joubert Okoume once I got to the plywood place. Couldn't resist saving a bit more weight on the back end of my 20SF. The Coosa is very pricey but one nice thing I found is it shapes really easily with a Surform. Mine has a 25" cutout and not bracketed btw.
