Thank you Frank. I took the drum into 'Machine Part Welding' in Penrose today (they do repairs on aluminum cylinder heads, amongst other engineering). The engineer described a process almost word for word as you explain above, which gave me confidence they could do the job.
Thank you Psyche and aardvarkash10 for helping work through the options. I am not sure yet whether Harken still supply these drums (waiting to hear back). I have found online 2 retailers in the US that have the drum; they are both seeking about $US3.6k (about NZ$5.9k) for the drum plus shipping. There is a 2nd hand winch for sale on ebay 'for parts', but the seller wants about NZ$5k including shipping from the US.
I will try repair (by the engineer), and keep a look out for a 2nd hand unit at a more digestible price. I will report back on how the repair turns out.
Kind regards
Kieran
Holy crap. At those prices I'd be making all repair attempts too!! Good luck.

I dont think this is an economical or practical repair in the long term even in the best case scenario, that said you could go down the quick and dirty route and just get it welded as is. File and sand to an acceptable finish while you find a secondhand winch.
Or grind it out, epoxy fill it, etc etc

It works well!! 100 mil per 4L, from less than 6 months prior to 2 + years, the odd wipe occasionally if the boat isn't used very often.
In what paint as a base?

Allow a couple of hours.
At least. Two separate machining operations (external and internal), plus the grinding and welding itself.
Good work catching the other one before damage.

1964 documentary series on islands in the Hauraki gulf. A glimpse into a past long gone.
The series was reprised in 2018 by the original presenters daughter. Those are also available on nzonscreen.

Cost of new drum vs cost of repair?

Caught in this as well, so I am asking the obvious lazy question - is it actually absolutely required to scrape back the old Warpaint?
Assuming the normal prep for a like-on-like over-coating is completed, would there be a problem just overcoating the old Warpaint with a different ablative eg #5?

Talk to boat haulage, if you were a back load you may be surprised at how affordable a truck is.
Once you look at time, buying all the extra crap we all reccomend, getting ready to sail?
Just a thought?
Plus 3 nights accommodation at the departure end getting everything ready, plus airfares, plus 10 days off work....

Well under budget there AD missed out yard fee. + haul out fee digger and truck $300 ph or more,we are not talking tonka truck or digger. Disposal of concrete could be free if they took to recycle yard in drury,it gets used in roading/constuction https://www.vernondevelopments.co.nz/aggregate-recycling/
I figured. I was trying to get it all in scale. None of this stuff is cheap and it takes surprisingly little effort to burn through $1k an hour on even a small demolition with easy access...

Read that recent article, and I still can't fathom how it costs eighty thousand dollars to dispose of a boat.
Assume 40 footer.
Project manage, $5k (consents, contracts, etc)
Tow to shore, make safe, 4 people @8 hours each @ $60 charge rate plus equipment, $2000 labour plus $150/hr towage and platform, so $3.5k
Break up onshore, 3 days, 4 staff, concrete cutting equipment, site safety, loader at $200/hr including operator for 16 hours, truck to disposal, two loads on a large tipper, hourly rate of $250, minimum half day. Disposal fees at $100 a tonne, say 25t of disposal.
Removal of toxics, oil diesel etc
Site clean and restore 4 people 8 hours.
Beer money.
Tons I will have missed, pricing isn't a quote but I would have thought light rather than weighted.

Antifouled in October. Scrapped a good number of barnacles off in Jan, and then more last weekend. What exactly is the anti foul doing?
Depends what af you are using and where you are located

...and two of the vessels having fuel supply issues (diesel bug?) on the main engines that made the situation increasingly difficult to manage.

those rudder issues eh...
For that in relatively benign conditions is appalling. I see that Alliance rebuilt the rudder and its bearing prior ot the race. I wonder if it was engineered, or built "good enough"

Check with Steve Hill, yard manager at Panmure BYC. He was a big fan of the stuff and may have some.

We ended up beach landing for pickup and on the pontoons returning
Beach landing tested my surf IRB skills and found them wanting.

Careful with that Silicone AntiFoul

Train as a biologist withe a double major in organic chemistry and then specialise in marine organisms and their susceptibility to different targeted chemicals presented in a semirigid polymer coating.
At the moment we are stuck in a double bind. We want a product that deters fouling, but we also want marine environments that support marine life.
If you use an effective antifouling and it relies on a poisoning process for effectiveness you will be harming the marine environment. The future likely lies in systems that are purely contact topical and don't wear off so cannot generally pollute, or systems that discourage growth through a non toxic mechanism eg ultrasound.
