Bottom paint effectiveness, like politics, is all local. I have had Micron 66 for the past 6 years and the bottom has to be cleaned every 2 weeks from mid July through September. That is considerably better than the VC Offshore I had previously which had to be cleaned every week. We are club racing weekly and 10+ weekend regattas or races each summer.
As a comparison to Doug’s harbor, if the speedo paddle wheel is left in for 4 days during that period it is completely fouled with shrimp and slime. So at the end of every weekend the speedo is pulled. Am in salt water though in a dammed river estuary and when there are heavy rains the ”river” flows over the spillway and the harbor probably gets a little brackish. Also am certain there is no shortage of fertilizer run off from the lawns of the homes on both shores. Micron 66 seems to be one of the better paints and it certainly is one of the most expensive.

Now I am using Blue Sea 45% ablative. still no cleaning. Have a diver replace my shaft zincs twice a year, he will also clean the paddle wheels for the knot meters. When the bottom shows signs of being dirty it is time to go cruising.

The boat was hauled and not pressure washed this Fall and had not been scrubbed all season. The bottom of the hull looked about the same as all those that had been pressure washed by the yard. I am most impressed with the anti fouling characteristics of Micon 66 compared to Micron CSC, VC Offshore and other high performance AF paints used in this area. The down side is that Micron 66 is not available in Canada. It contains higher levels of copper than is allowed here. A pity since this paint would likely reduce hull cleaning costs by over $400 per season for a typical boat that races.

Micron 66 is very effective in controlling algae growth, at least it is in our climate....for all of those that are bottom cleaning every month, maybe Micron 66 would minimize that work. Just a thought. Rob Abbott AZURA C&C 32 - 84 Halifax, N.S. On 2014/12/23 12:35 PM, Bill Bina - gmail via CnC-List wrote: I looked at Dri Diver before making my rig for about $15-$20. In fact, it was my original inspiration. One big difference is that my system can do the keel. I also wondered if the scotch brite pad might be a little too aggressive on my ablative bottom paint. Different strokes I guess! :-) Bill Bina On 12/23/2014 11:21 AM, Gary Nylander wrote: There's an outfit called Dri-Diver which makes a device like you described. I hope they are still around, because I need a new scrub pad. It is about 6 inches wide and 3 feet long. A scotch brite style pad hooks to a plastic (maybe 1/8 inch thick) backing strip which has half a dozen cylinders of floatation hooked to it (crosswise). All is attached to a plastic pipe handle with a bit of a bend in it. There used to be a lesser version with just a single floatation pad on the back, but after I wore that one out, I got the special model with the cylinders. The only downside is that you cannot reach the keel. I use it between diver trips.

It makes bottom cleaning at a slip a short, and relatively easy job. I'm now on a mooring, and have to work my way around the boat, tying the dinghy to the railing as I go. It takes a little longer and a little more work, but it is still not that hard to do. I'm not a racer, so this method is more than adequate. I'm sure a diver would do a better job, since he can see what he is doing. I use the same rig to do my outboard rudder from the cockpit. Screwing the broom head directly to the boat hook does not work very well. In addition to the pool noodle floation, I also added a curved extension made from plumbing so that the broom head is offset from the boathook by about a foot. That clearance makes all the difference in reaching the center area of the hull without the boathook hitting the hull. I think I have some pictures of this thing on my home computer. If I can find them, I'll post them somewhere on the web.
