Iceboat Foam/Carbon wing mast construction for C Skeeter

This is the start of a new 12" wide x 20' long wing mast for my C Skeeter iceboat. This is for the boat named "Drifter", sail number I-291. It has been many years since I cut foam like this and I am far from being an expert. The foam gives the shape of the mast, and then gets covered in many layers of carbon fiber, which provides the structural strength.
