Shape : Triple concave to deep double concave.
Comment : The Third Arm is a cross over between an hybride shape and a fat shortboard.
It as the look of a fat shortboard, everything is oversized to get even on a small size a lot of boyancy. The Take off is very easy!
The bottom shape come from an high performance shortboard (triple concave with a very deep double cooncave under the back foot to maximise wtaer flow), the board stay very handy and fast despite its high volume and round curves.
