Cut the balsa blocks into rough, blocky approximates of their final shape using a bandsaw and a few test fits, taking care to make sure all surfaces of the block protrude a little beyond the edges of adjacent frames. This will save you lots of sanding time, even though a 60 grit pad on a vibrating sander EATS balsa quickly. Below are shown the midship blocks for my model. You will probably only need some at the extreme bow and perhaps the stern.

This is the blocky mess I sanded down at the bow. It doesn't start off pretty, but it is at the finish of sanding.
