Waterline weed

[xhurleyman]

Good day ladies and gents. I have Coppercoated my boat but regardless of burnishing the Coppercoat occasionally I still get waterline weed, can I antifoul on top of the coppercoat down from the waterline about 4 inches. Will it stay on and be effective?
Thanks.

Either brush it off or go for a good sail. Weed on the waterline won't be stopped by antifoul.

What MoodySaber says, go sailing.

If it is just the waterline a quick rub with a scrubbing brush will get rid of it. If it covers the hull lower down then that might need a lift out

I get the same and it get to 8 inches long in as little as 3 weeks. Comes off easily with a stiff brush but copper coat really needs a start of season and a mid season jet wash if you want to keep the hull clean

We scrubbed 2 weeks ago and already have a fearsome amount of green waterline weed/beard. CuPro antifoul. I think it's just to be expected at this time of year and in this weather regardless of which antifoul you use.

I've been feeding the weed with Hempel Tiger and had an impressive fringe this week. I had a go at it with a scouring pad on a pole. A brush wouldn't have touched it.

I recollect that the ‘father of modern ecology’ (https://en.wikipedia.org/wiki/G._Evelyn_Hutchinson) once said that ‘life is a function of interfaces’ (I paraphrase) and on waterline fouling I console myself with the thought that he was right.

Same here, a fringe of weed along the waterline. Not due to a lack of sailing, as you might suspect, we have clocked up 2200 nm so far. Last year we had the same, with a similar mileage. I’m beginning to wonder whether the active ingrediënt in Micron gets washed out after a certain number of miles. After our trip, when the boat gets used less, the weed starts to grow fast. The rest of the hull only has some slime. Next season the waterline will get an extra layer of AF.

Ooops - just started a similar thread. I have just pressure washed the weed from around my waterline - worked a treat - no scrubbing and no wet and weedy brush to sort out. She was afloat alongside a ponton at the time.

Thanks all of you, so its another bit of elbow grease. It has nothing to do with sailing as I have been for the last three months! It just grows when it wants to. I will get some pan scourers and go and dry out soon. I just thought there might be some new antifoul which would halt or slow down this annoyance!

I think the resin that is used for copper coat is epoxy resin which is waterproof when set, whatever is in the copper powder in copper coat i feel is locked into this waterproof layer .. have you tried sanding the surface to try to expose some of the copper to the water.
Having said that I was told that Copper is good against shell type fouling and not as good for weed and slime.
