I intend to Coppercoat Charlotte this coming spring, in addition to this I am taken with the idea of filtting an Ultra sonic antifoul system as supplied by http://www.jaycarelectronics.co.uk/productView.asp?ID=KC5498. As I understand the system the Ultrasound prevents the build up of slime and algae that the growth feeds on, its that slime and algae that renders the coppercoat ineffective.  One of these kits is effective for boats up to 32 feet. Current thoughts are to fit two; one positioned forward port side below heads and the other aft starboard side beside battery's
Any words of wisdom appriciated

We Coppercoated a couple of years ago and initially were pleased with its resistance to growth. Since we've moved up to Scotland we've sadly found it less effective. Coppercoat themselves suggested that this might possibly be due to less salinity in the water, especially after heavy rain. Something that Scotland does rather well!
Having said all the above it is still a layer of epoxy and its a lot easier to lift and jetwash her off, which we have to do to service the Darglow prop anyway, than re-antifoul.
This year we are 'wintering' (since the end of August!) her ashore and we are having the waterline re-Coppercoated to try and boost its performance.
Would be interested to hear how the Coppercoat/ultrasound experiment goes.

Doesn`t Calypso  installed an ultrasound antifaul ? unfortunately, they've also combined it with a new experimental bottom paint, so hard to tell what`s more effective.

We haven't switched on the Ultrasound this year because first of all we wanted to see how we got on with the Hempasil (silicone based foul release used on commercial shipping to great effect).  We'll try the Ultrasound next season, but at the moment we think we might just use it when in habour, and the Hempasil when under way.  There are no simple solutions!

Can you tell me how many and where you installed the ultra sound transducers on Calypso. The information of the Jay care site suggests one transducer for up to 32 feet.

We installed it under the quarter berth.  Yes, just one transducer is supposed to cover a 32 foot boat.

Further to my November post we have now been informed that our Copper Coat has failed and that the whole lot will need to be removed, this is after just three seasons!

Coppercoat has to be correctly applied onto a properly prepared hull surface.  If not, it will fail.  How was it done, and by whom?

I'm not going to name the company as I have the utmost faith in the work they have done for us in the past and in the fact they have done numerous boats previously.

In January 2009 we found ourselves in need of having a repair conducted inside, due to a collision that had taken place the previous summer whilst Tiptoe was unattended on her mooring. Fortunately the offending party owned up and this was all conducted under their insurance.

This seemed like a perfect opportunity to apply CopperCoat in the required conditions. Prior to entering the shed the hull was blasted down to the epoxy primer that had been applied in Summer 2006. I also asked the yard to take some dampness readings of the hull which they did and were are found to be perfectly acceptable.
I'm not sure what other precautions we could have taken?

This is very strange.  Have you been in touch with Coppercoat themselves?  They are usually very helpful.
