Chainplates...

Eric and Paul have designed integral carbon fiber chainplates for this boat - very light and strong.

6mm ply backing plates go inside the hull.  Starting from the
blank at the top, the ply is tapered with a hand plane then glued
to the top inside surface of hull strake #4.


A cutout at the top of hull strake #4 is marked and cut.

Garolite (G-10) is a high strength epoxy-grade industrial
laminate sometimes called phenolic.   A 1/2" thick G-10 plate
was routed with a carbide cutter to accept a G-10 tube.


The assembly glued onto the hull.  Layers of carbon laminate will run up the outside of the hull over this structure and down the inside of the hull.


Simon Miles spent a day in my shop showing me how
carbon laminating is done.

The finished laminate covered with peel ply

Speaking of Simon, here is the beautiful keel he made me.  He also
made my bowsprit and is working on my mast.

The cured chainplate with excess laminate removed.  After the cabin sides go on, two notches will be cut in these chainplates to accept toggles for the standing rigging.  An additional single chain plate will be added to the cabin side.
