Has anyone else suffered with accelerated growth build up this year?
I launched in March with a new and nicely polished prop (polished as normal). By last weekend I had lost 7-800 rpm and 2 knots of boat speed. A diver scraped it clean again and as if by magic the missing revs returned. He said there was a 3mm growth of crispy barnacles on each side of the blades.
Although our boat usage has been down slightly this year, I've never suffered like this before (3 years in Port Solent and 50 in Portsmouth harbour).
