The process of learning - aged antifouling

Pacific Blue and an underwater job to keep the
speeds up above 6 knots in the doldrums
I was reflecting on why we did or didn't do certain jobs earlier.
Mostly we did the preparations that enabled us to sail independently without breakdowns; but for those sailors attempting ocean crossings, this  re antifouling job I would bring forward. On hindsight the toxicity of the paint had already been lost.

The anti fouling simply was not working, which required cleaning far too regularly. Twice I dived her clean while in the open ocean, (which also allowed me to spear 3 mahi mahi for a feed.)

Start scraping with 3/4 inch tungston blade - days of work.

 So in NZ under the advice of the yard owner (Charlie), we stripped all that antifouling off and haven't had to dive with the tiger sharks in Morton island since.
 


500 discs to prep for painting .

Hardest part to remove was where the  first coat 
of  antifouling was bonded into the epoxy.

The primer coat on and now on the easier homeward journey



1st Coat of Epoxy, all coats are colour coded

2nd coat and weather still good

3rd coat and refreshing the masking

2 coats in one day, bonding in the 
antifouling while the epoxy is still tackie
