Inspecting a yacht's stern tube and getting to grips with a dinghy that would not come out of its mould

Having removed the stern tube out of the yacht this is what was found.

A radiual fracture around the whole of the tube 

A possible cause is the rusted away bolts holding down the deadwood 

This dinghy refused to come out of its mould so now its going to be cut up.

The mould is now washed and polished ready to be release mould waxed and a new dinghy is going to be laid up.
