5'11" x 18 x 2 3/8" Deck to bottom rail before concaves (or 2 1/8" with calipers deck to bottom concave) at widepoint
Here's how you can lay out your template if you want to try to shape one yourself...
- N1 = 11 1/8" Wide
- N2 = 16 1/8" Wide
- Center at 35.5" = 17 7/8" - 17 15/16" Wide
- Wide Point is 18" and runs from the Nose back 37 3/4" to 40 1/8"
- T2 = 17.5"
- T1 = 14"
The Swallow Tail is 4.5" across, pin to pin, or corner to corner before you cut the swallow in. The swallow can be 1 1/8" to 2 1/8" deep... or traditionally, it would be half the width of the tail (2 1/4" deep).
The board thickness before concaves are shaped in is 2 3/8" @ the center through wide point area, from Deck to bottom... after concaves are shaped in, a caliper reading will read 2 1/8" (because you are essentially putting 1/4" of single concave in the center portion of the board.
Rocker: using a straight edge with the fulcrum point in the center of the board (35.5" from the nose), measure the distance from the bottom edge of the nose to the straight edge. Do the same for the tail....
- Nose rocker: 4.5"
- Tail rocker: 2 1/4"
Bottom Contours: Single Concave with Double Barrel Concave running throughout...
- N1 has 1/16" of Single Concave (the Double Barrel doesn't start until 1/3rd back from the nose)
- N2 has 1/8" of Single Concave and 1/16" of Double Barrel Concave
- Center (35/5") through the Widepoint (from the nose back 37 3/4" to 40 1/8") has 3/16"-1/4" of Single Concave and 1/16" of Double Barrel Concave
- T2 has 3/16" - 1/4" of Single Concave and 1/8" of Double Barrel Concave
- T1 has 3/16" - 1/4" of Single Concave and 3/16" - 1/4" of Double Barrel Concave
(The Board length is 71", so 1/3rd of that is 23.666666666666666666666666666667")
The board works well as a Tri-fin or a Quad...
HAVE FUN!
