The Continuing Issue of Electrochemical Damage To Our Wooden Boats – Lady Ellen


 

The Continuing Issue of Electrochemical Damage To Our Wooden Boats

 I recently received an update from Bruce Mitchinson on the restoration work underway on his 36’,  McGeady built (c.1950) classic launch, Lady Ellen. Unfortunately the old lady has a been struck with a dose of electrolysis.

You can see when the secondary shaft log was removed, electrolysis had destroyed the planking around the plate fastenings. The same problem around the main shaft log, and strut fixings, through structural members, which were all bonded together. The affected timber has been removed and new kauri blocks glued in and around the shaft log, keel bolts and floors.

The to-do list this week includes laminating up pilularis frames insitu, to replace the 15 broken, or electrolysis affected members that have been removed.This will complete the inside structural work, below the waterline, that had been put off until things dried out enough.

Other work has seen the old fuel tank removed and a clean up around the bilge in the engine bay Following this Bruce will be working his way forward with stripping and refastening on the outside of the hull.

The shaft, prop and drive couplings have gone down to Whangaparoa for adjustment, set up, and balancing.

Hats off to Bruce for doing the best of Lady Ellen. To read more on this problem, the causes & remedies – visit Chris McMullen’s WW story – link below. Its the most referenced story on WW.
