The Shapers Layout Square - Dims

  • 24" in width | 609mm

  • 12" in Height |  304mm

 How to use:

The Shapers Square ensures quick and accurate surfboard design measurements. Use the top of the Shapers Square for inches and the bottom for millimetres.  
Surfboard’s Tail and Nose: Measure the surfboards wide points 12" from the tip of the nose and 12" from the tip of the tail. Place the bottom line (the 12” mark) on the Shapers Square at the tip of the blank, line up the centre line of the square with the stringer and make the 12" width measurements for both the tail and nose.  
Surfboard’s Width: Line up the Shapers Square Centre Line with the blanks stringer (ensure the entire centre line is aligned over the stringer). Keeping in line with the stringer, slide the square up and down the blank to mark out your surfboard design width’s.   
Surfboard’s Fin Tow Angle Markings      
(A) Measure and mark, on the stringer, the distance up from the tail that the fin­s will be set at. Move the Shapers Square up to the level (A) Line      
(B) Align the Shapers Squares vertical (B) lines with the stringer in order to keep the measurements true. This will allow the Shapers Square to remain level while moving the square out towards the rail to mark your ­fins placements.      
(C) Slide the Shapers Square right or left keeping (A) on the measure mark and (B) parallel to the stringer.  Mark a dot at the 0” cut-out hole, at the distance you want from the rail to the trailing edge of the fin (known as the “Shapers Dot”).       
(D) Use the 4” or 4.5” cut-out (depending on the base length of your fi­n) to mark the front tow angle of the fi­n.

    layout and fin placement square

    Posted by Rick March on 8th May 2019

    I bought this square to replace my old, well used Pleskunas layout square. I'm impressed with the quality of this square, it's twice as thick and therefore more ridged than the Pleskunas. The graphics and measurements are vivid and easy to read. Having the fin layout locator is a bonus. The layout square has both standard and metric scales (metric across the bottom). It came well boxed, and in it's own envelop. The only adjustment I made was to enlarge the hole to fit on my hanger. I highly recommend this tool.
