Re: Bottom paint on prop
Over the years I have tried many things and up until now nothing has worked to my satisfaction. Having said that, I have been sort of experimenting with the duration of the bottom paint and have recently extended the time between haul-outs to 30 months and I have found that the biggest impediment to this is the prop and shaft which look like a mussel farm after 24 months.
Normal anti foul will last a few months, International Trilux maybe a little longer but any ablative paint will wash off quite quickly. It's not about boat speed, it's about prop blade tip speed.
I am reliably informed by friends and colleagues that this stuff is the only solution:
My boat comes out in two weeks and I'm going to try it but unfortunately it will be two years before I can reliably report back.
I got to test out "prop speed" on my haul out in Tauranga in 06. It did a pretty good job for 2 years in between haul outs. Most of the time spent was passage making between New Zealand, Fiji, Vanuatu and Australia. Since we were not sitting in any one place for long it seemed to work well. I was given the "prop speed" on a "mates rates" deal. I would not pay for it now. I'm in the water enough to take care of any fouling on a regular basis. If my boat was to sit for some time, I think a coat of bottom paint would be ok.
