This is really good discussion and the drawings are a terrific resource for the 36XL and 37/40+ owners.
The design of the centerboard on the C&C 36-1 KCB of the 1980's vintage is different. The "board" is really more of a blade, not nearly as elegant, but it is also quite heavy and takes a similar amount of resolve to raise it up. I haven't heard if pendant failure causes similar destruction. Mine failed once at the dock with apparently no issues. I would love to see drawings for the 36-1 KCB. I'm planning to call that library up north that has C&C build files, but it keeps slipping down the list. Soon, I believe I will need to replace the metal pendant tube that goes from the cabin top to the centerboard well. It appears to be worn through at the lower radius, which is below the waterline. Fabrication drawings for the pendant tube on a 1980's vintage 36-1 KCB would be really helpful. Has anyone seen those? -- Tim Rutherford tim.rutherford.m...@gmail.com 813 748 4888 cel/text On Wed, Oct 2, 2019 at 4:59 PM Charlie Nelson via CnC-List < cnc-list@cnc-list.com> wrote: > Hey Bruce, > > In C&C's effort (probably Rob Ball) to minimize the drag/turbulence etc. > of this era's boards, they were made 'elliptical' such that no matter how > far the board was lowered, it fully 'filled' the trunk opening which > reduces drag, etc. from what would otherwise be an large opening where the > back of the board meets the trunk.
