Well, mate, I'm really glad that you don't have to deal with us whinging yotties any more. We are all cheapskates and hate to part with a dollar...
But, from both personal experience and observation of many other boats around Australia
, Prop Speed does work. On our boat (in which we average around 5000 miles per year) Prop Speed kept our Flex-O-Fold three blade prop free of fouling for a year. We slipped for routine maintenance
at the end of that year and were unable to source the materials to reapply the coating, and so left it alone. It continued to work for another 6 months, but then began to show bare spots and those spots attracted the usual growth. We just slipped again, again after 12 months total, and found the prop to have around 25% of the coating still visible, but very thin and not working well, so it is fair to say that it had totally failed at that time.
The manufacturer of the product only claims 12 month viability, and that seems to be accurate. Note that during this period we traversed waters both tropical and damn chilly, latitudes ranging from around 17 to 44 degrees South, and thus were exposed to many sorts of fouling organisms.
So, Otter, while you may not care what I think of your "suggestions", I believe that saying that all the "fancy stuff" (in which I would assume that you include Prop Speed) does not work is inaccurate and misleading. There may be situations where it is less effective, and improper application can reduce its lifetime, but for many of us it is the best antifouling agent for propellers that we have yet tried.
