The Full Balsa Surfboard – for Maximum Twang

Balsa has the highest rate of flex return of any material used in lightweight composite technology.

When applied as a skin to the Sunova precision machined shapes, this sweet natural material also gives you the highest performance option.

As with a Springer, the Sunova full balsa surfboard adds another dimension of spring to a sandwich board:- an unrivalled degree of sensitivity and spring from any part of the board.

Sunova’s individual balsa patterns and grain mean no two timber-skinned boards will look the same.
However, after working with balsa for so long we have arrived at the weight, density and grain structure that give the magic formula, board for board.

Strength and long term durability in your surfboard, are also at their greatest with The Sunova Full Balsa.
