Was 2024 a bad year for fouling in Suffolk and Essex

Every year my 28ft yacht is lifted out of her Ipswich Marina home for her annual TLC. The few small patches of fouling where the second coat of Cruising Performer wasn't applied properly induce feelings of mild embarrassment. There may also be perhaps less than a quarter of a bucket-full of sea-squirts hang down towards the aft end of her hull.

Since being launched last September and lifted out at the end of August this year, her hull has become badly fouled. Also, for the FIRST TIME EVER in her eleven years of residence in Ipswich Marina, she'd acquired an infestation of small mussels. Her rudder always gets more than two coats of a/f paint because it's a handy surface to work the paint out of the roller before a tea-break. Much good it did this year because the side that sees most sunlight had a solid coating of them.

The sail-drive propeller was installed last September and, because it was new, it got a liberal coating of Hempel aluminium (?) anti-fouling spray paint along with the drive leg. (I used Hempel because Fox's didn't have any of the Tri-Lux I've always used satisfactorily.) I might as well have used Dulux house paint for all the good it did, and Tri-Lux may have been no better.

The point of this post is to ask if other people with boats moored in Ipswich Marina and other Suffolk/Essex places had a similar experience of excessive fouling this year.

Also, amongst the normal dark grey mussels were a few brown ones. I reported them to the government scientists and unfortunately my photographs were not good enough to identify them as the same as the invasive species that's been discovered near Southampton recently. More container ships from all round the world visit Felixstowe than Southampton, and if you find any brown mussels the government's scientists would like to know.

I'm on a swinging mooring in the Twizzle.

I've tried a number of different antifouls over the last few years and found nothing that keeps my hull free of fouling for more than a few weeks after launching. Many other boats in the Backwaters seem to have exactly the same issue with rapid buildup of grey/brown slime and green weed that I do.

Contrast that with twenty or more years ago when any mid priced antifoul would keep your hull squeaky clean all season.

We did the antifoul in early April this year, we have a lot of fouling already, including mussels visible on the trim tabs. We'll need a lift and scrub before we use the boat next Spring, usually only lift every two years.

Launched late this year and already noticed a drop in performance so will scrub on some posts. Does seem worse than normal but I haven't used the boat as much this year either so that won't have helped.

Just for balance, in the Medway I’ve scrubbed our boat 4 times this year since launch in April, last time was on Saturday.

I think you lot get off lightly in the Orwell!

Micron 350 worked well for 2 months.

Fellow Twizzler, launched 02/08 after repairs. Slime after couple weeks, barnacles and green weed around lower outboard bracket and tilt trim unit very established after six weeks. Seems like growth forming more rapidly that when in Titchmarsh marina last season.

Fairly average I would say, in Titchmarsh. We used to foul very quickly in Maylandsea creek and my theory was that the movement of silt-carrying water quickly coated the bottom and rendered the antifouling inoperative, and I think the still water in the marina is less problematic.

Deben based - last season we were badly fouled, particularly on props, shafts and rudders but we had been in for two seasons. This year, whilst speed has dropped off a bit, it is doesn’t appear to be anywhere near as bad as last year. In addition we haven’t had the ‘beard’ around the waterline that we had in previous years.

We applied Velox prop anti-foul to the stern gear this year but won’t know how good it has been until we next lift out.

Boat lifted out of the Twizzle yesterday.

Despite three beachings and scrubs this season the fouling was the worst I've ever seen. The entire hull was thick with brown/grey slime, there were several tendrils of green weed and a number of barnacles.

I thought it was going to be pretty bad as flat out I made barely 3kn instead of about 5.5 through the water on the way to the slip and I wasn't wrong. Guy doing the lift and pressure wash said every boat he'd seen this year had been the same or even worse.

Such appalling performance from leisure market antifoul clearly isn't a one off then and it's getting increasingly ridiculous.

I retracted my log transducer last week, which had been in for two or three weeks. It was thickly fouled and stank to high heaven in a sulphurous way.

It would be interesting to know what anti foul is being used for those who have suffered bad fouling.

International 300 and Hempel Tiger Xtra on the Alde.

Tiger Xtra, SML paints Cu Pro and Hempel Hard racing on The Twizzle.

None of them have been able to keep my hull clear of fouling and slime for more than a few weeks in either location.

I find that I need three thick coats of hard antifoul to overcome the lack of additives in antifoul paint. Plus regular scrubs with a Scrubbis tool . This keeps me clean for 2 years before coming out.
When I was in the chandlery business some years ago , there were complaints that we passed on to the antifoul makers. In every case where the hull was accesable, it was found that recommended coverage had not been adhered to.

Nail on head.

The lack of effective additives is the real problem here. UK legislators have gone further and faster than much of the rest of Europe in progressively banning a whole host of effective biocides that were introduced after the ban on TBT in 1989 and the leisure market had suffered accordingly with hull fouling commencing within weeks of launching.

Compare that situation with some 20 or 30 years ago when a couple of coats of antifoul would protect for a whole season.

Whether the relentless banning is a result of a genuine concern for the environment or a cynical attempt to screw even more money out of the sailing community through creating a need for more regular marina lifts and scrubs and selling even more antifoul at £100+ a tin for the wretched stuff is anybody's guess.

I managed to get a mid-season pressure wash and scrub for £45 a couple of years ago, but this is something I seek to avoid. It was certainly the case in the days when I was working a 1:2 weekend rota and every one was precious to me. In recent years a late launch has helped, but I was only really happy in the years when we did 3-month cruises and would come back from the Baltic or even the Channel with a clean bottom in late August. Nothing quite compares with our years in Heybridge Basin where we scarcely fouled at all.

Whatever you do, the little beasties and weeds are out to get you. In one year we visited the West Country and towed the rubber dinghy for a while. I have a photo somewhere of the dinghy with visible barnacles after only three weeks’ immersion.
