New Bottom Paint

[Tawney1]

Will be having our 61' hauled in two weeks for bottom cleaning and bottom and running gear paint in Wilmington (NC). Had her hauled and painted 2 years ago July. Our diver has indicated that the bottom paint has not held-up as well as he'd like, but we've had her out for a few 100 miles each year and we have a brisk current at the dock (sometimes as much as 3 knots). Previously we used CSC Micron paint on the bottom and propspeed on the running gear.

I would appreciate any suggestions, recommendations, and/or thoughts about new paint or whether to just stick with the CSC Micron.

Thanks,

Paul

Try micron 66. It may need the old paint removed or a conversion coat.

The micron 66 is some good stuff, it has to have a prime/base coat to work properly , I want to use the micron 66 but It ws out of stock @ the time . I used the micron Extra & I went in back in may, I had the boat pulled 2 weeks ago & the bottom was clean as a whistle, there was a bad barney out break @ the marina, Warwick RI . I expected a mess & so I was kinda surprised when the bottom was clean. the micron 66 may not be the best pick for your boat with the constant current, it is may to ware down, like a bar of soap as it was explained to me....the extra is a harder finish Both good products..

I use Sea Hawk Qcote with biocide. 3 coats and 5 at the waterline. Last job lasted 4 years.

We have had great luck with Petit - Trinidad anti slime in the Charleston area. 2 coats on the bottom and a third along the water line since we have a strong current as well.

That's what I have used (name is actually CuKote) here in Morehead City for the past 4 years, just touching it up with a single coat after 2 /12 years. We too are in a high growth, high current slip, requiring a diver's services every month, mostly for the running gear (to which we apply nothing). We use the boat year around. I have had the work done by Jarrett Bay.

Many thanks fellows for your suggestions and comments. What prep other than pressure washing does the CuKote require? Sanding? Primer?

I spent most of the time at the dock last year, working and living on the boat. From Jan-May tied tight to a floating dock. The ablative didnt work well as it needs lots of water passing by to shed the growth. I was told by Petit that the ablative needs 20 mph water flow to be effective. Every week you need to go out and run it up. Well that counts me out. I only can run 17 mph (WOT). Normally I travel 7.5kts sipping fuel. I'm going back with hard paint next Jan. 2014. As far as Propspeed, it works fine as long as it is installed properly, and you run every weeks also. Another thing, if you run in the ICW, you run the risk of getting into shallow water (silty mud) and burning the slick stuff right off the props. Ask me how I know. Anytime you are Kicking up mud, you are sanding off the very expensive coating. However, fishing charter boats love it. Just my two cents and the petit rep. They want you to be happy with their products so you'll buy more. Most prep requires a good sanding and cleaning the surface. Make sure the boat yard sands the hull at the same price. Some yards add that cost as extra. Some dont even remove the intake screens and paint inside. Oh that would be extra too.

4 plus years on 2 coats of micron 66. I have had years with 100 days on the water and other with little use. I did hit 20 kts 2 or 3 times in perfect conditions but cruise at 7 or 17. Trinidad is not the way to go. I had it on my previous boat and the results were poor. Less than a year and it was getting hard growth.

Seahawk did not do well in this area.

Csc is not 66. Try the best forget the rest. Fyi I have no affiliation with the manufacturers.

 

[Boatsb]

And I forgot.



no hard growth to speak of yet.

 

[Tawney1]

Thanks for all the great comments. If I go with Micron 66, what conversion primer, if any, is recommended? Seahawk has a barrier coat primer it recommends if there is unknown compatibility. But since we used micron csc previously, that should not be an issue. Right?

 

[Boatsb]

I believe you still need a conversion coat like interprotect . Check with the local interlux tech people not the salesguy.

I'd vote for Micron 66. Best paint I've ever put on my boat. I'll be repainting this winter and will use Micron 66. I would never consider using a hard bottom paint. If you've ever stripped years of hard paint build up of the bottom and started over you'd understand why. I've never heard that you need to run at 20mph for an ablative paint to work but typically I do. I know many who use ablatives with excellent results and never run fast.

 

[magnawake]

Yeah Thats true. I cant say ablative didnt work for me as well. It's been 2 1/2 years since I painted the bottom. Another thing, since it was my very first time ever, I didnt know how ablative was supposed to work so I cleaned the hull myself. When brushing the hull, I would get a big blue cloud of paint in the water. I thought the paint didnt cure or something (ok, i see yall laughing). I think I took alot of the paint off. However, it still lasted this long. Most yards in the Stuart area, Ft Pierce, say go with hard paint if your a trawler type sitting at the dock mostly. Man, thing grow down here fast. We didnt get that much grow where I was he last 2 years. I'm just repeating back what the yards and the petitt rep told me I should do.

I have five years on a Micron 66 bottom paint job. Every year I ask the yard to repaint the bottom and every year they tell me it doesn't need it. We do repaint the area right below the boot stripe, touch up a few other areas, and use Pettit Barnacle Buster spray on the metal parts. Considering that Blue Note stays in her slip from April to November and only goes out every two weeks, I think this bottom paint performance is excellent. At least in this area, I recommend it highly.

I have decided to go with Micron 66. Now only need to determine what conversion is needed. Per suggestions, I will check with Interlux tech.

Just want to say thanks to everyone for your comments and help! I am so proud to be a member of this forum with such helpful and kind members!!

Now, on to new batteries, battery boxes and repairs where old boxes are located....

Let us know what you find out and how you make out. When I bought my boat it was time for new bottom paint. PO wasn't sure what they used the last time he painted other than it was Micron. The yard that did mine said it wouldn't be a problem using Micron 66 over Micron CSC or Micron Extra. I checked with Interlux and their recommendation was to lightly sand and clean were needed. The Micron 66 could be applied over Micron CSC or Micron Extra as long as the bottom is in good condition.

Pulled the boat on Thursday and the bottom looked fantastic. Last time she was hauled and painted was 5/11. Boat was down south until 7/12. Brought her to NJ 8/12 and she was been here since. Always in the water and very little use since Sandy hit. Ran her about 65NM Thursday and she ran smooth and fast. I was concerned the bottom might be fouled and we would run slow or hot. Boat ran 18.5kts @1800 rpm and 22kts @1950. eng temps stayed right at 172. Fuel burn was under 200 gallons. When we hauled the boat the bottom was exceptionally clean. No signs of hard growth on the hull only on the metal. Very little slime other than at the water line. No signs of the trace coat underneath either. Looks as if the boat was painted less than a year ago. Needless to say, I'll be putting Micon 66 back on.

 

[jim rosenthal]

Me, too. After four or five years, it is finally time to recoat the bottom (although there is actually no hard growth anywhere but the metal parts) Micron is getting thin. You can't argue with five years on a bottom job.

That's great performance. Do you haul out for the winter every ear or do you stay in the water? I only haul every 3 years but may go back to land storage for the winter.
