A dozen of the leading antifouling paints are put to the test and rated by MBY in The Solent and the Mediterranean
Seajet 038 (prototype) £tba
Proving that registration of paints can be difficult, the launch of this new Seajet paint has been delayed by 12 months. However, we’ve included it to see how the future of paint looks against today’s offerings
This is a self-polishing paint so can withstand moderate speeds, but anything too racy may cause premature eroding and shorten its life.
COLOUR FASTNESS: 5/5
The Seajet started as a perfectly traditional white and at the end of the season it still looked exactly the same, with very little staining even from the dirty water – an impressive result for
a white paint.
In the Solent and Mediterranean locations there was no sign of any growth, but at the East Coast location there were a couple of weed attachments across the panel. However, they were only small and barely visible.
SLIME CONTROL: 5/5
When lifted there was very little slime at any of the locations, showing it to be the cleanest panel on test. Given that all the panels remained static during the season, that’s a fine result.
WASH TEST: 5/5
The finger test removed most of the slime that was attached to the board and washing removed all remaining traces, leaving a totally clean panel that looked as good as new.
This Seajet paint would have been our best performer but regulation problems mean it won’t be on sale until 2017. However, it’s good to know that the latest generation of paints seem better than ever and we’ll let you know when it does pass the tests.
Seajet 031 Samurai £49.95
031 is a self-polishing paint that can withstand speeds of up to 40 knots. Marketed at the budget end of the market, it has less biocide than some
Although the paint dissolves in water it still requires some movement of water to keep it clean and can withstand speeds of up to 40 knots. Regular high-speed use will see it wear away faster, so is best suited to a boat that isn’t driven too hard for too long.
COLOUR FASTNESS: 2/5
The Seajet started off a very light shade of lilac, despite being called shark grey, but it quickly turned a strong turquoise colour around the waterline when exposed to salt water.
In all three of the locations there was no sign of any significant barnacle or weed growth, despite some build-up of slime.
SLIME CONTROL: 3/5
The Samurai paint managed to keep the slime at bay on the East Coast, although the growth which was there had formed a blotchy pattern on the panel. There was a slightly thicker build up near the waterline of the Solent panel.
WASH TEST: 2/5
The finger test didn’t remove as much slime as we had thought it would. It was a similar story when we sprayed it down with a marina hose, which cleaned off some of the slime but struggled to shift the hardest fouled areas.
On initial inspection the Samurai paint performed quite well, but despite being a fairly soft eroding paint, which usually perform better in static tests, the fouling which did occur proved resistant to our attempts to wash it off.
