Antifoul Puzzle

[Pete7]

Used it for 3 years in a row I think. As previously reported it failed in 2013/4 but that could have been down to water temp, lack of use and location. Previously it did work well with only slight green weed around the waterline for 3". We chose white btw which apparently needs more colouring agent so less good stuff. Would go black or blue next time and it doesn't wash off like Micron or Uno.

Whether the IOW chandlers or Marine Superstore will do a deal on 6 or 7 tins would be worth asking.

You will need a paint stirring widget, ideally in a drill, to mix it as it does settle badly, but can be stirred back to life with 5 minutes of effort per tin.

Ah, just remembered you are after two years between painting. You may or may not get two years with Seajet 033. In your favour is lots of sailing, a summer spent in cool waters and seajet is reasonably hard so potentially may stand multiple scrubs with a pressure washer. Just the second year will be an unknown as most folk in the UK re-paint each year.

Micron Extra and Uno are so soft a cloth or as I tried a soft mop creats clouds of blue water if you try and scrub in the water. I couldn't even bring the mop back on board without risking staining the white GRP a blue colour.

How many coats will 15L give you? we need 6L for two good thick coats on a 31ft yacht, two keels don't help here. Arthurs Chandlers my local are convinced folk don't put enough on which is half their problems, hence we use Uno as its in 3L tins at £60 a tin, rather than Seajet 033 which would need two and a half tins at £75 each and what do you do with the half tin, may as well use it.

At the risk of being accused of hijacking..........................

I use Hempel Water Glide - here in the baltic, this has worked very well for us. I haul once a year, pressure wash and repaint. But the Baltic waters are not very salty and we generally don't ahve growth problems.

Now the question -- we're leaving on an RTW. What paint should I use?

I'm expecting that waterglide is not the right one.


any suggestions??

Not hijack, but healthy thread growth

I'm also curious to hear what people say about this. The tropics are a different bag altogether for fouling.

At least you dive (right Carsten?), so can clean the hull yourself.

3 layers of something soft like Micron Extra. When you reach the Carib, blast it off and stick that Trinidad Petit on that everyone recommends on here. Buy extra tins and take it with you for another paint when you reach the South china Seas.

Can you bring some back for me please

yes I dive and have all the equipment - so does vinni my wife - maybe I can send her down?

One of the many, many benefits of bilge keels, is that you don't have to be blocked off ashore -- just crane out. So should be cheap and easy for you to be ashore for a while to do this every year.

For me, it costs, because they have to build a whole structure to hold the boat up. That's why it is very beneficial for me to avoid antifouling every year. This expensive Micron 77 will pay for itself a couple of times over if it lasts for two years.

My Jotun Sea Queen always lasted two years without any problem, and didn't mind being jet washed 8 or 9 times between reapplications.

A key skill. I'm trying to find time to do the PADI source myself.

I actually have the equipment, which Pete was kind enough to inspect for me. The only thing missing is time . . .

I realize paints preform differently in various waters but I'll share my experience anyway. I've used Pettit Trinidad on boats in New England, Florida and now California. Here in fairly cool water with 2 coats (3 at the waterline and leading edges) I get 3 years between haul outs for repainting. I do have a diver scrub the bottom monthly which I understand is less practical in the UK.

I scrape the hull with just snorkel gear. Love to do it as all the fish join me to get to the goodies. Didn't like the remora that tried to attach to me though

Yeah, yeah. Tropics.

My Daughter told me Remora's are just like teenage boys

Bet you thought that was too much information
