The outline is that of a stoker nose and a shortboard back end pulled into a round pin/thumb tail. The wide point is pushed right up the board to increase the rail line which gives you the feel of a shortboard when you have your back foot on the tail pad, and the nose is nice and wide which is great for paddling into waves quickly.
The rocker is fairly unique on the Doofer, it has a medium tail kick which is fairly curvy to the bottom of the rocker into a drawn out entry rocker; providing you with the best of both worlds when it comes to hold, pocket surfing and speed. The deck is packed full of volume means that you can ride the Doofer fairly short without feeling under-gunned when the waves get a bit of size so the balance of using it in smaller waves and bigger waves really helps it to be a versatile board.
The concave is that of a charge model from the tail to the wide point with a single running slightly deeper through the nose, helping it with paddling and lift in the water when you need to maintain your speed on the smaller waves but really gives it some hold when you are surfing off the tail-pad in bigger waves.
