ANTIFOULING CHANGES

[alibaba 84]

Yes, I know, here we are again. I've been in touch with the Altex rep because for the first time in 15 years I'm having problems with Altec No5.

I got more growth and barnacles than ever, plus a few new greeblies.. The rep told me that they  had not changed the formula, but were experimenting with new stuff as they acknowledge that the environment has changed.

I see that Burnsco is promoting an AF I haven't seen before - SeaHAwk AF33, more expensive [ of course!].

I  haven't managed to find out much about it - has anyone tried it, used it, seen any reports on it?

"The trailerable AF-33 and Smart Solutions, the only completely metal-free paint in the test, also repelled barnacles. Both, however, had moderate coats of algae that would require cleaning to remove. "

A lot of the paints are not available here. I think Micron CSC is the only one available here.

 I bit the bullet and went back to International Ultra 2 but waiting for travel lift to complete maintenance.  Quayside boatyard,  Mahurangi river.

Seriously thinking of going back to coppercoat as have joined HIBC that has a grid to wipe slime of regularly and reburnish.

Yes Altex did change formula a year or two ago, confirmed by the lacal Altex rep down here, I am having he same poor performance. Will change away from Altex next repaint in 16 months time.
