Sorry for the late reply! (For future reference, the quickest way to obtain a quote is to contact us via www.coppercoat.com
or by callign 01258 861059.
But to fully treat a 28ft motorboat you would need about 6 litres of Coppercoat. At the current r.r.p this would be £420 plus delivery and Vat. And all being well this treatment would increase the boats performance slightly, decrease its fuel consumption slightly and continue to work as an anti-foul for approximately a decade.
But if you come to see us at the Southampton Boat Show (stand D005 in the Windward Hall) you could claim a discount!
