I'm 5' 9" and 180 pounds I have surfed a funshape 8'-0" x 22" x 2 3/4" for a long time and for the last year or so ive been trying to surf on a 6'-6" x 17 1/2" x 2 1/4" shortboard. I have a problem with sinking the board, and losing all my speed by the time i do stand up. Any tips on popping up? Is the board i ride to skinny and thin? Is a wide and thick shortboard / fish a good new board to purchase?
