We arrived back in the UK from our extended stay in Spain about three weeks ago. We had a couple of weeks staying in Essex with Mother before farming Fletcher and Floyd out to my brother in Norfolk while we dashed up to Yelvertoft and recovered Yarwood. All this week Yarwood has been at Debdale Wharf where she has been taken out of the water, jet washed and transferred to an enormous shed for a bit of deep cleansing...
Yarwood after her washing with a powerful jet spray is loaded onto a trailer for transportation to the gritting shed.
Mike carefully reverses the trailer into the shed
Carefully placed under the tent canopy, four jacks are put in place to take the load and the trailer is carefully removed. At the press of a button Martin lowers the jacks to bring Yarwood to the optimum height for work to begin.
The tented canopy is secured to protect the upper half of Yarwood and then the lower hull is grit blasted to get her back to bare clean steel before a hot coat of molten zinc is applied.
Joe examines the 'gun' that applies the zinc coating
It's Friday afternoon and the two-pack blacking coat has been applied and work is starting on the bow sides/flare
Masking removed and one bow flare is revealed
Starting to layer paint on two of Yarwood's three tunnel bands
Yarwood will stay in the shed over the weekend to 'cure' and then Monday morning we will present ourselves to pay the bill and get our boat back.
Certainly is Neil and will the bank account know it!,Delete
I've not heard about the 'hot coat of molten zinc' method before...ReplyDelete
Am I right in thinking that it offers superior protection for the steel?
p.s. welcome back BTW :)
Thank you k2Delete
The zinc coating will protect the hull from corrosion and the two pack coating, which is harder than a bitumen finish, will aid that aim.
Welcome back. Sorry we did not see you before we departed on our extended trip. We are having the same work done in Oct so it is good to see the pictures.ReplyDelete

I am very impressed with the molten zinc spraying. How does that work? Is the zinc in the form of a wire that is melted at the nozzle? What is the heat source?
Thanks for any information you can supply...
Hi Bob, The process is known as electric arc spraying. Basically two lines of wire (in this case about 2.5mm thick) carrying a high current are fed in separate lines and when they enter the gun an arc is formed across the wires. The subsequent molten metal is blown by compressed air onto the workpiece. Normally the wire reels etc are only a few metres from the "gun" . However this is not practical in this application and the wire/air lines have been made especially long. JoeDelete
Wow, that looks a thorough job! Looking forward to seeing you in May...ReplyDelete
Ditto..I will come armed with doughnuts!Delete
