Anti fowling paint
« on: November 03, 2019, 10:20:12 PM »
I looked over the entire forum and think we need a thread dedicated to anti fowling bottom paint. My wife talked about leaving the boat moored for summers in the salt.  I had planned on a black graphite bottom treatment.   The lists of bottom paints is nearly endless. 
   Lets start a report listing paint types and performance here!

I agree ... some real experience would be great.  There are new coatings and products out there too.  I've never kept a boat in a slip for the summer or year around, but I know that if you leave the boat in the salt year around that you use a 'soft' or 'ablative anti-fouling pain', and if you trailer more often than how long the boat stays in a slip, then you use a 'hard' or 'non-ablative anti-fouling paint'.  The hard version needs recoating far less often, and the soft one usually requires annual recoating.  Having kept one boat in slip for one summer, a gel-coated glass boat, and dealing with the growth issues ... I'd say that it's not a big deal.  You hose down the bottom of the boat with a strong ammonia mixture, spray off with a jet of water, repeat.  It comes off without too much work.  Given that, I suspect that the non-ablative 'hard' anti-fouling paint would be a good choice for you and it would at least minimize the pre-winter storage clean-up work that you have to do.  More than this ... I dunno.  It would be nice to hear some real-life experiences on this.

I have had good luck with Pettit Hydrocoat. Very clean bottom after 4 months in the water.

My favorite local marine store sells Interlux and Pettit.  The phone guy recommends micron and vivid respectively.   I read reviews and testimonials on both.  There is as many mudmouths on each as there is glorious tales of anti fouling badassery.   Sooo.  I guess I will just nut up and try the one that I have the best chance of success.  Given my level of skill, shop, and temps this time of year.   
   Im open to suggestions as always!

Yesterday I covered the boat with graphite epoxy.  I used the level line as described in the plans.  I went 8 down from the chines at the transom.  I found out my spray rails are 1/4 different at the aft end.  No surprise I guess.  I looked at lots of boats and there is so many different ways to paint the bottom.  Im not married to anything yet.  I tried to follow the rails curve and could never get it to look right.  I may try following the chines and mirror the the smile in the rails this weekend, just not sure how to handle the paint at the bow.  It is tough when a person doesnt have imagination  Im not sure how I like it as of now.  Im getting pretty anxious to flip.  Opinions and observations welcome!

I did the same thing (laser level) and I was thinking my bottom coating looked uneven due to how far below the chine junction at the bow looked, but yours looks about the same, so both of us can't be wrong right? :) I think I will probably go with it, since I have it basically already done. Looks great though, how many coats on the bottom did it take you to get it color saturated like that? I think I am on about my 5th coat, but I am going super thin and needed to fill the weave as well.

That was 1 coat.  I will cover it with clear epoxy just to be safe.  I did have at least 2 coats of clear epoxy on before that.  I just scooped the graphite in the mix  not measuring.  Just needed some contrast

I like that too.  I dont know if 1 gallon would get two coats covering that much hull given the paint coverage of my paint?
