Bottom Slime - Does it come off after a sail

Look at the Davis Scrubis and related products. I thought it couldn't work, but with the Groovey head, I'll be darned if it doesn't work on slime.

The trick is that the floating head does the work. Push it down, and it scrubs on the upstroke. Not as good as diving, and not for hard growth, but good for touch ups on light soft growth. I used it in the shoulder seasons, when there is some growth but it is too cold for swimming.

Scrubis
Like many in the UK I'm also a habitual user of the Scrubbis kit. I note that your US price of a Scrubbis is around £48 UK compared to the price here of around £93 UK . I know we have an NHS but it is quite a difference. I notice that diesel was selling at £1.72 a litre today.

Anyway, the Scrubbis works very well for me although barnacles can cause tear damage . In my case I had to modify mine using synthetic grass and Velcro which works well.
 
A few dinghy sailors at our club this week & there was an open meeting. A few ended up in the drink & apart from their results, they did not seem to let it worry them. I shall be working on the water all this week & next & have to admit, that whilst I felt the same in my youth, I certainly do not want to try it now.
I bet none of those dinghy sailors were wearing a wet suit, but a dry suit so they did not wet. Back in the late 1960's I remember sailing with my brother on Boxing Day off the Isle of Sheppy. We wore wet suits, but did not drop in the briny. There was a gust of wind that was recorded as Force 9. We had the gaff jaw of the Mirror break and with an offshore wind, we could not beat back. Most dinghies capsized and the rescue boats were overloaded with rescues. We rafted with a 420 and awaited a tow. It must have taken about an hour and a half, despite wrapping ourselves in the sails, we were getting cold. Once we got back to shore and stepped into the water, it felt warm. We must have been close to suffering from hypothermia. Never went dinghy sailing in winter again.

I did the Aldenham Sailing Club Boxing Day race once, and once only. It was blowing some sort of gale and I was sailing my Firefly in a wet suit. That is to say, I was wearing ordinary clothes that got very wet. My boat, with its mast in the horizontal position, was blown ashore, where I gracefully retired to go and resuscitate. I think we’re we’re required to wear buoyancy aids, a rare event.
 
Getting in the water without a wetsuit at this time of year is not recommended in the UK. You might not come out. Woosss or not
From 2001-2019 I did rescue boat duty for the club in the whole polar series. This was because I was always sailing my cruiser in the summer so could not take my turn then. I only ever wore a wetsuit. It involved launch & recovery of the RIB, often waist deep then placing race marks & sitting watching fellow sailiors sail the course whilst wet. Obviously helping those in bother. That occasionally involved a dunking for me if, I had to sail a boat back for an exhausted crew.
It never bothered me, although my hands suffered by the time I had recovered & washed the RIB down. In the early 1990s I did the polar series a few times in my Phantom & even a sailboard. All in a wetsuit.
But then a few wears working on a building site in the snow, with a bunch of Irish groundworkers, does something to ones brain- although what, I am not sure :oops:
 
I sail in Cardiff and moor my boat in the bay which is fresh water. When I go thru the Barrage it is salt water. I use my boat a lot and have very little build up of anything on the hull. The theory is Salt Water kills the fresh water stuff and vice versa. Most people in Cardiff antifoul every two years and have little growth of anything.

Not recommended by whom?

A good mate of mine is 81 years old, and he usually does Burnham Parkrun (that's a 5K run), in a not too shabby sub-30 minutes.

But he's not really what I consider to be a proper, truly dedicated, runner.

He reckons that the secret to his youthful looks, luxuriant hair, longevity and excellent general health, is that he has swum in the Crouch, at Creeksea, every day, summer and winter, for decades.

No wetsuit, no drysuit: he wears only his swimming trunks.

He's built up quite an enthusiastic, local, following (the majority are women).

I've been tempted to join them, but I realise that I'm far too much of a woose to wade through the icy mud, with bare legs, in the depths of winter.

But he and his entourage seem to thrive on it.

Good for him.
You sometimes see these people around swimming in the sea in winter, but most of them are in and out in minutes.
I thought we were talking about the average Joe scrubbing his hull in the water without a wetsuit. Most people wouldn't last 5 minutes in summer let alone winter.

Great story btw

Maybe my mate is missing a market opportunity ....... year round, in the water, scrub-down, anyone?
 
Dust on an airliner’s wing before flight will still be there after it’s flown. It’s to do with the boundary layer conditions.

Likewise on a boat, in the boundary layer water flows past the hull far slower than the speed of the boat. In fact, in the boundary layer closest to the hull, there’s no relative flow at all.
It probably then explains "dirty car syndrome" . After having a dirty car washed and waxed it's not an illusion thinking that you are slipping along much better.

Scrubbed my hull today, there is no way I could have done it without a wet suit!
