What are surfboard blanks made of?

In: Surfing [Edit categories]

Answer:

They are made of polyurethane foam.

Answer

They are made of foam, but not always polyurethane foam. The king of polyurethane foam boards was Gordon "Grubby" Clark. When he closed Clark Foam, he left a big void that other technologies (like expanded polystyrene foam, epoxy foam and composite foam) helped to fill.
