and yes, the brown stuff on her bottom is rust. At the bow:
and stern:

there are things called "sacrificial anodes" (see this link for more on how they work). By some strange alchemy they stop the steel rusting. The problem is that these are too old and have stopped working. They're also too far apart so they aren't protecting the middle section and so she is suffering from pitting in the middle :-(

The real worry was what the bottom plate would be like! This is a single sheet of steel 68 feet long and almost 7 feet wide.
So Steven Hands and his lovely assistant (no photos to protect the innocent) from Hands On Marine came to give their professional verdict. They spent several hours measuring the thickness of the metal all over with a nifty little ultrasound machine and finally pronounced their verdict...
Despite some nasty 2mm deep pits on the sides and base her hull is in pretty good shape for a boat of her age and she doesn't need any overplating or other remedial work. Phew.
She does need to have 4 sacrificial anodes down each side and a very thorough "blacking" every 2 years if I am to stop the damage from continuing. Eventually the pits will become too deep, turn into holes and she'll sink so it is important to have had this survey done. Now we know what needs to be done and where to keep an eye on. The boat yard boys at Norton Canes are going to get started on that immediately.
Her propeller and rudder aren't the right size or in quite the right place but the cost of fixing the problem is disproportionate to the improvement in handling. "She's a 23 tonne, 68 foot, cow. She's never going to steer like a Ferrari." A fair point well made I thought.
So all of that was a very long way of saying that I haven't got a lemon. She is a good solid boat and is worthy of some TLC.
But...
The day was not all good news.
The work that does need doing - especially a complete re-paint which is definitely required to stop the superstructure rusting away, and taking out and re-fitting all the windows and portholes to stop them leaking - is going to take longer than I'd hoped. In a way that is the problem with going to a proper boatyard that won't do a bad job. They're craftsmen and they won't be rushed. It could be as much as 6 weeks. I had hoped for 3 and resigned myself to 4 or 5.
This is going to be a long, long lent.
