[C38] Headstay Length?

[Tom T.]

I never knew it was called a "Tick Stick" but this is the technique I have
used for many years to contour my boat trailer bunks to the compound hull
shapes.

I currently have a Laser sail dink and two PWC's on trailers that have
bunks formed with this technique.  The bunks fit perfectly to the hull with
no gaps anywhere.  This distributes the weight of the hulls evenly giving
maximum support by the bunks.
