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

Holy crap. At those prices I'd be making all repair attempts too!! Good luck.

Or grind it out, epoxy fill it, etc etc

well they won't get liver flukes...

Ablative

In what paint as a base?

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. https://www.nzonscreen.com/title/islands-of-the-gulf-rakino-and-kawau-1964/quotes

Cost of new drum vs cost of repair?

He's posting video on Facebook for those with social media addictions...

dammit....

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?

Plus 3 nights accommodation at the departure end getting everything ready, plus airfares, plus 10 days off work....

technician time is not free.

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...

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.

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.

Ooookay then...

Can anyone comment on the viability of tying up to pick up at Maraetai to passengers? We draw 1.7m

With a flapper disc...
