|Who would think that such a teeny weeny hole could cause so much expensive trouble?|
In the lower part of the photo is the cause of our woes, When they built the boat they used pea shale as ballast, this contains salt and is a perfect medium for holding moisture. This caused the bottom to rust from the inside and caused the skin cooling tanks and their balance pipe to rust through so that they too leaked into the pea shale.
We just completed welding on the new base and plug welding the centres of the panels to prevent sag, Next we need to overplate the leaking parts of the skintanks.
Tomorrow I'll clean the hull so that we can give her a few more coats of blacking before she's refloated on friday.
