This antifouling lark is a real minefield. From previous threads there seem to be several different ways of doing this. I am going to go the leave in the water route again next season - it is a bit much to keep pulling boat out on my own.

But which one to use?
Copper - will it really mess up an outboard engine?
International.... which one?
Smoothskin (or whatever it is)?

Do they effect performance?

Do some last longer (I know copperbot claims about 5 years...).

And the tubes?????

would leave mine in the water if i was closer to the sea but also intend to try different places, i sympathise with people who have to keep antifouling as it seems a pain but you gotta do what you gotta do

Forgot to add - have had a test plate of steel coated in the stuff since March - wedged into rocks in a rough water tidal area so exposed to pretty much everything - will work ok on slower boats but don't know if it will last long enough on something like a RIB!!!

Hmmm.... I reckon you need to test this in slack water where weed and other growth will be more likely to accumulate. I hope you had a "control" test as well with a "placebo" coating?

correct and grows more on the hull facing south (towards the sun) than the other side. I don't worry about the tubes because they are clear of the water at rest.

Whilst antifouling is a pain its once a year event and takes a weekend. Which one? well tried the cheap stuff this year and it didn't do it for me so back to International next year.

I kept a hardboat in a marina (May-Oct) for years, un-antifouled. The rule of thumb was- drag it out every 4-6 weeks and would be only soft green weed which came off easily with a pressure wash. 6 or longer it became more stubborn, after 7/8 weeks the barnicles would appear. A tip for an outdrive is to cover it in a black plastic bag when not in use. It's a bit of a drag, but no light, no growth. It does work.

Yes I have - the coated plate has no growth at all and hardly any rust spots - the uncoated one is rusty as hell and covered in weed and barnacles. It really is very impressive but I wonder if a few high speed runs will dislodge it - only one way to find out!!!
