Building up cutout transom

Hey Hoover, is it true Niedermeyer got shot by his own troops?

Contact HermCo, a moderater on the site as he has the requisite knowledge on flotation brackets so you get the balance and C.G. right. I highly recommend his brackets/experience for this. The fill is a lot easier to do from the outside. Don`t know what your core is, but you could lap ply and glass the fill from the outside. Easier in mho.
