The inner liner had a slot with cover that was about 3" wide to allow access to the keel bolts.
We started drilling with a 1" spade wood bit through the inner liner.
The wood underneath was like compost: black, wet, squishy.
Using various spade bits, regular drill bits, chisels, and a dremmel tool with vavious attachements, it took me close to a week working 3to5 hours a night to get all the rotten wood out. The only wood I left was at the ends, where the wood was very solid. Everything around the keel bolts was taken down do the lower fibreglass of the keel sump.
Here you can see the initial drilling |
This is a good shot showing the wood, fibreglass, and keel bolts |
Here you can see how the fibreglass was cracked!! |
