Plow vs Single

This boat, believed to be a Shoenbroad (sp?) was donated to the club at the end of a season. Unfortunately it didnt find a home indoors and ended up living in a snowdrift for the winter. We think the plow hit it while it was covered with snow. 2 years later the new bay at CRI means I was able to rebuild the hull and get it ship-shape again. Now weve just go to track down the riggers...

To start the repair I laid up a couple layers of fiberglass against the hull near the damage. This gave me a panel that pretty closely matched the curve of the hull. I bonded the panel inside the hull to replace the inner skin. The brown around the edges is epoxy with microballons to fair the edge and make the inner skin watertight.

The Fiberglass is yellow because of the resin, its just regular 120-glass.
The second stage was to replace the core. This green core is a closed cell foam that is flexible and easy to cut. I matched the thickness of the original honeycomb core and weighted it down so that it would bond against the new inner skin and match the curve of the hull.

I was never going to exactly hit the hole in the hull, so i got it close and filled in the gaps with more microballons and polyester. I was aiming to still be a little below the level of the orignal hull, to allow for the thickness of the outer skin.

Here is the outerskin patch curing under vacuum. The boat is mostly kevlar, so I patched with kevlar, but I covered the patch with fiberglass to hopefully make final sanding easier. (Kevlar frays when you try and sand it. This makes it very tough but also hard to fix)
