Section 2 Keel and Rudder
Keel: With a C26CA approved trapezoid, mark the keel forward
(A-2) and aft (A-1) edges.
Using the Class approved template, position around the keel
at these marks. The ends should just come together.
If there is play, then the keel shall be filled to this minimum
design shape. Shape shall be consistent in the vertical
plane fore and aft. From the aft edge measure down
thirty-five inches and mark the keel. This will be A-3. From
A-1 and A-3 measure to intersection of transom and hull just
to one side of the rudder. This is HDP (Hull Data Point)
