Tow or Kite board surfboard.
This is a DHD copy. 6’1 x 18 1/4 x 2 1/4. Its glassed heavy and has removable straps. This was specifically made for towing behind a boat, I got sick of snapping boards so had this made. It’s got 6/6 diagonally woven glass on top and bottom, high density foam skin on top and bottom. It’s pretty much indestructible. I had the straps added for kite surfing.
