triple concave photo

anyone have photos of triple concave on a board? i dont have a board that is easy to access to see.

It will still be difficult to see from a photo (unless someone posts a shaded drawing). Your best bet is to go to shop or take one of your buddy’s board and lay a straight edge on the board from rail to rail and move the yardstick or whatever from nose to tail and take note of the position of the concave, it’s depth and how the single concave flows into the double.

In a recent edition of one of the surf magazines (“Surfing”-I think?)there is an ad for “Channel Islands” which contains a picture of Al Merrick working on an early tri-plane hull. The photo was taken in a shaping bay with the side lights casting shadows across the bottem.
