On 568, I have a custom centerboard that was especially made to fit the trunk snugly enough to eliminate all side-to-side movement. As the spruce foil was was glassed and gelcoated, it became a snug fit indeed. It fits so well that it often becomes lodged in the trunk, which has resulted in my breaking one handle and bending the replacement to a point where the board now cannot be lowered completely. :oops:
I have taken the CB out , sanded down to the glass, and reinstalled, but it still get's stuck. I've come to the conclusion that I need to fair off the glass, sand the board thinner and reglass. I know it's crucial to duplicate angles precisely, and to use some sort of template.
In a previous discussion on fairing the CB ("Boat Pox!"), Michael Shriebman, aka, Captainsesick, mentions downloading "scaled templates for an 00XX NACA airfoil, [transferring] them to cardboard forms and [building] the centerboard to this model."
Can the good captain--or anyone--elaborate on said templates and where to find them?
