Seajet 033 antifoul

[Forest Girl]

I bought 2 tins of Seajet for the first time this week. My boat is a Fulmar, 9.7 metres. I thought 2 would be enough. No chance. Also it had separated badly and took a lot of stirring and shaking. Still had lumps. Does this stuff have a sell by date? It is really runny stuff and rollering on is a real messy business. Lots of spray!
Anyone else had experience of Seajet? PLease tell me it is gooing to be worth the 200 quid!!

Three years ago I was tempted by two tins (5 l) of Seajet Shogun, half price in the local chandlers. It was obvious that it was old stock but I used Seajet for years and had kept it without problem. When we went to put it on it was really hard to stir, the copper seemed to have congealed into a thick gritty lump at the bottom of both tins. We persevered with big sticks and eventually achieved a reasonably smooth looking emulsion. After the two coats dried it was obvious that there were rusty looking spots of copper all over. I took some photos and emailed them to both the retailer and the importer. The retailer referred it to the importer as well. Their response was impressive, after a short telephone discussion they sent two tins off by carrier. Unfortunately both were abused in transit and arrived dented, leaking and covered in navy blue paint. When I reported this I was sent two more tins and warned me to be sure to dispose of the first pair responsibly. So I applied them to the boat, (seemed the most responsible thing to do). I kept the new tins for future use and they kept well for a further two years. (The wetted area of my 33' boat is not great and I usually get two coats from about theee to four litres using a roller.)
So Seajet keeps, but not for ever, but if you can show that it is defective you may get some new stuff. It is certainly more effective here than the Blakes that was applied when the boat was commissioned. I first started using Shogun long ago when it was coming from Japan in the belief that the Japanese were more likely to make a strong poison than any one in Euope. The Dutch who make it now may not be as irresponsible but I still like the product and the very dark navy shade they do suits my boat's colours and does not seem to absorb the brown peat stains from the canal water she sits in for weeks at a time.

Seajet coverage

I have used Cruiser Uno for the last five years but found it was less effective when I was in the med at the beginning of this year. On the advice of local yachtsmen in Cartagena I applied two coats of Seajet before I sailed back at the beginning of August. So far here in Brighton Marina there is no sign of anything growing on it. My Spanish friends only apply it every two years out there.

I used 6 litres for two coats rolled onto my Rival 36 (11mts) which is quite a slim boat with a narrow derriere. I think it would have gone further if I hadn't put the first coat on in bright sunshine.

It did take a lot of stirring.............

I've used it for tha last 3 years & am OK with it. I'd prefer it if there was no growth but I guess that's too much to ask. I generally get a few barnacles & some slime. Nothing too bad though. I'l use it again next year.

I'm in Chichester Harbour on a swinging mooring & quite a few peole use it here. That doesn't meen though that it will work as well where you are.

I'd agree, it does take some stirring though.

I have used Shogun for several years. It is important to stir it very thoroughly indeed as the copper does sink to the bottom. You should continue to stir regularly during application. If the paint has stood for some time, pour off some of the liquid, this makes it easier to vigorously stir up the thick copper at the bottom without it spilling. Then progressively add back the liquid until you have a smooth emulsion.

I find that roller application gives the best finish and even coverage.
When well applied it is very effective here on the East Coast and no doubt elsewhere.

As Edmund says (Hi Edmund, I´m Manuel) Seajet is one of the best antifoulings you can use, up there in your cold waters or here, in the Med. It is a high density paint with a high ratio of copper and other biocide particles per gramme of paint, so it does a lot of stirring.

As far as I know, if there is any problem with the paint, either the distributer or the dealer will have access to guarantee and will give you a new tin in return.

had it applied by a Greek who soon after, went to jail!

(for other things) I wasn't impressed as we were thick with weeds after only three weeks afloat and the yucky pale blue did nothing for the boat.

Somehow I couldn't see myself going back to the chandler who sold it and quoting the UK "Sale of goods & Services Act"

That was the last time I paid anyone other than a trusted friend to A/F my boat and the last time I've used anything other than International Micron Extra. I will be at the boat Tuesday morning having left her in Gouvia Marina for several weeks. I am confident that before I get half way down the island on Tuesday afternoon, she will be clean as new. I do two coats by roller every April but I might be tempted to miss a year one day or only do a single coat since there is usually loads of active paint left by January lift-out.

Well, that's my experience and I'm not going to change my view of my product preference.

Used Seajet 033 for 3 years, boat based Falmouth, afloat April-early November, comes out pretty clean on one thin roller coat each year all over and a second coat on the six inches round the waterline - one 2.5 litre can just does a 35 ft hull.

I try not to build up antifoul thickness as I like the hull smooth, and do some wet sanding each year as well before the new coat. It really does need a drill-stirrer, you can't just wave a stick about in it. Halfway through doing the hull it has thickened and needs a trace of thinner and another power stir.

very happy with seajet shogun 033 in portsmouth harbour - worked well this and previous years - if only we could beat the growth on the prop!
