I also had to get the hull surveyed for insurance renewal as Blackbird is about 28yrs old now. I must admit, I was a little nervous at what state the hull might be in as I haven't done the blacking for about 4 years but the surveyor said it was in good condition and the anodes still had some life left in them too! The only work he did recommend doing was to have new outlets to my 3 sinks welded as the steel was eroded under each outlet. The boatyard did the work promptly so I wouldn't have to pay for an extra day in dry-dock. I was away when the boat needed to come out the yard and they moved it for me to somewhere convenient. So yes, I'd definitely recommend Bates Boatyard for good friendly service and reasonable rates. I also like that all their prices are on their website so you can work out up-front what it's going to cost.
