Antifouling choices with an eye to buying a Nemo

Jay, I cannot think of any boat antifouling that works on Props. They will all "spin-off" quickly. Hemple makes some good products. They make a primer and antifouling for Props. Hempel's Prop Primer - 101EX is a spray primer and "tie-coat" for antifouling Hempel's Ecopower Prop 7446X - 7446X is an antifouling for Props In my opinion, there is nothing perfect for Props, especially in the Caribbean. If you are in a marina for longer than a few days, it is best to dive and clean the propeller, especially if it is an AutoProp. Every marina will have divers or divers on-call to do this for you. Probably the best antifouling (IMO) for Props worldwide is PropSpeed, but it MUST be applied exactly according to the instructions. One owner I know says to apply PropSpeed correctly with protection lasting up to two years it requires two people because the top coating must be applied as soon as the base coat is applied and if only one person is applying it, the first portion of base coat will be too dry for the top coat to properly bind to the base coat. The second best to PropSpeed (IMO) is Velox which is a two-part application (base & top coats). Bill

We applied 3 coats of micron in 2018 in Malta. Due to COVID, we did not haul out until 2022. After 4 years, one of which we could not make to Kokomo due to Covid, and sailing the rest for about 5 months every season, we would simply hand wipe the hull once at the beginning of the season and not have any further issues. There is usually some growth towards the stern at waterline, but nothing major. We have been happy with propspeed which has done very well for at least 2 years in the Med with minimal to no growth. We did the same in 2022. Micron antifouling and propspeed. We had sent our Bruntons prop to the factory in the UK for service and balancing. After service, they applied the propspeed at the factory, I think using one of their vendors. They have excellent service and customer support. The prices were also competitive and reasonable. We simply installed the new prop.
Happy Sailing;

I agree with you about both Micron and PropSpeed. I consider each the best of the best.

If you are going to aggressively clean, you will NEED a hard paint. The best in my experience is still Trinidad. It should easily support a 2 year haul schedule.

Thanks everyone for the input.
That makes me feel more confident about the propspeed: We will put that on. Thanks Bill K for the hint on Trinidad. I will put that in my notes. I am going to stay with the ablative for now and think about it when we are in the Caribbean. I've had recommendations from a couple other sources recommending to wait to do the transition to hard coat till we are in the Caribbean. The quote to do it in Europe is rather high. Interestingly, The Hyeres people recommended Micron so I will check with them if I can put that on over the Hemple or if I have to stay with Hemple for now. Regards, Jay |

You have to be a bit careful when talking about “Micron” bottom paint. It is actually a product line from Interlux that currently is composed of at least 5 different paints, with different characteristics. Some are water-based and some are copper free. The most traditional of the bunch is Micron 66, a copper based ablative paint that is excellent in most areas. The only catch is it is not recommended from fresh water. The material that causes this paint to “ablate” or slowly dissolve simply dissolves too quickly in fresh water. One our cruising plans started to include significant time in places that were significantly fresh(*) we switched to SeaHawk BioCop. It has worked very well for us from Nova Scotia to Grenada. We get 14 to 18 months of clean bottom without manual cleaning. |
