The previous night, I mixed up some wood putty and filled cracks in the hull piece.

Here's a close-up of one of the spots that was filled. This is prior to sanding.

This is the deck interior with cracks filled.

This is one of the spots on the deck interior where the yellow cedar meets the red cedar at a point. There were many low areas that needed filling here. This is prior to sanding, it should smooth up all right after sanding.

This is the other area where the yellow cedar meets the red cedar.

A look at the hull interior after sanding. I'll run across this at least one more time.
