Midseason scrub?

[chubby]

So when is mid season and when too early to need it and too late to be worth it?

The boat has been in since march, always goes well when clean and slows up by October.

Early in the season when the water is cold there seems no growth then it catches up but too far into the season I have done my big trips and it doesn`t seem worth the effort ?

Try putting a bit more antifoul on, then you won't need a mid-season scrub!

Mid-season is one of:
* The week before your annual two week holiday cruise
* The week before you sail against your arch rival in a race
* The point at which more than 3 people have suggested the vegetation growing under your boat could qualify it as an area of special scientific interest

What difference does that make?

If you can dry out, you could have a look and see what the state of play is.

Fouling is strongly related to water temperature, in my experience. In my 6 month season, it’s generally on the last couple of months when fouling takes hold. In July/August I’ll dive under the hull (dry suit and scuba) and brush away the light dust coat with a hand brush. The prop gets a scrub, too. A few weeks later, I’ll use the dinghy to remove the water line beard.

This, plus the AF gets weaker over time. Weaker still once you've scrubbed of course.
We do a bit of racing in the Autumn, a lot can grow in 3 weeks then.

Modern antifouling doesn’t work all year iswhat I’ve found. A mid season scrub works wonders.

We had two coats of Jotun seaqueen 60 applied by the Hayling Yacht Co. April 2017. We sailed all summer, she stayed afloat/on the mud in a HYC tidal mud berth all winter.

Due to the bad winter, when we wanted her lifted in April this year to attend to stuff and clean the hull, there was no room on the hard as other HYC clients had not yet completed their winter jobs.

So we used her. A little green-a few tufts of weed- could be seen around the stern, and towards the aft where the hull shape is nearer the surface. When sailing, little or no speed loss.

Lifted last week, hardly anything bar a few tiny barnacles which just wiped off.

Fitted a new Orbitrade suffing box on an extension tube, cleaned the boot line, lubed some seacocks and the yard is attending to some GRP dings, most from the previous owner, but a couple down to us.

Not antifouling this year, and hopefully not next.

I'll let you know,

PS. The excellent Jotun antifoul products are hard to buy in the UK for self application. They are availible in Ireland, IOM, Holland and no doubt other places. They are, without doubt the best and most successful antifoul products I have used.

Not an ad, but HYC will supply and apply Jotun at their Mill Rythe yard. I find their charges are fair and resonable.
