Copper Shield 45 is a multi-season ablative bottom paint with 45% cuprous oxide content for protection in moderate fouling waters.
The paint's copolymer base renders a smooth finish with durability and abrasion resistance. Copper Shield 45 provides anti-fouling protection against barnacles, algae and hydroids in salt and fresh water on boat bottoms only.
Blue Water Copper Shield 45 has universal application over all types of properly prepared bottom paints (except aluminum). It can be applied directly over properly prepared ablatives, epoxies, and vinyls, and most any other hard or ablative bottom paints. This ablative is perfect for powerboats and sailboats, fast fiberglass boats, as well as wood and steel hulls.
Available in gallons or quarts. Choose from Royal Blue, Marine Black, Admiral Green, Regatta Red, or Bright Blue.

How many square feet does a gallon cover?
I last painted my 32 ft full keel sailboat with Blue Water about 5 years ago. I believe I used 1 gallon, maybe a little more. I still have about 1/2 gallon left just to touch up any bare spots from flaking annually but the paint seens to last forever, however it does tend to flake, maybe I put it too thick. Yhe boat is in fresh water now and the only real bottom lover is slime but the Blue Water handles slime very well.
Did you prep the bottom? I have ablative paint on the boat now and was wondering if I have to sand it off or just power wash and paint. Light sanding or take it all off?
I used three and a half gallons to apply two coats to a 42ft roughwater power boat.
I used 2.5 gallons to paint the bottom of a Beneteau 411 (39 ft waterline x 13 ft beam). Hope this helps.
I was able to get a single coat on a 28 foot sailboat with just a tiny amount of paint left over.
The adverstised rate is irrelevant. One gallon will more than cover a 33' sailboat with a 6 foot draft and 11.5' beam one coat with plus a second coat on the leading edges. Order more than you need as it lasts. You will be using it again the following year - its very good stuff.
I don't know square feet, but I got the complete bottom covered on my Pearson 10M (33' sailboat). It has a deep keel and displaces 13,000 lbs. This is my 4th year using this paint and it works very well in my area (Mt Sinai, Long Island NY)
3 gal. give you 2 coats + leading edges on 36 feet Beneteau boat.
Thanks, I have a 42' Tayana 12' beam 5'8 draft. I'll go for three gallons and keep the leftovers.
I'm in Atlantic Highlands, NJ. 37ft cruising sailboat. Where do I find out about what ablative paints are legal or encouraged in this part of NJ?
I am not familiar with "legality" of various bottom paints in NJ waters as I don't sail NJ waters.I do know that Blue Water Marine Copper Shield is a very good antifouling paint with excellent slime control. I first began using it about 5 years ago after reading a good review in "Practical Sailor" - have not been disappointed. I am not aware of any restrictions on use of this paint in our oceans as it is widely used by commercial shipping.Would suggest that the manufacturer, Blue Water Marine - see their web site- , is best qualified to answer John's question.
Ask your marina if they have any restrictions. They will know. You don't want to ask what is "encouraged", ask what people are using that works.
I have this on my boat now, but the green is too light. Do you think there would be any issues with mixing a gal. of the green (which was a little skinny for a full coat on the Alberg 37 last year) with a qt. of the black and getting both a darker green and a better coverage?
I've never done it but I don't see the problem with mixing colors of otherwise identical paints. If in doubt google Blue Water paints and ask their customer service people.
We use the green also, but have never mixed colors. I had a question about their products, and called the support number on the Blue Water website directly. They were very helpful..
Applies on smooth!! Easy to Use!!
I sanded the fiberglass, removed mold release wax, cleaned the fiberglass, applied Barrier Shield,and then Added the Bottom Shield. Follow the process, and your project will have great results!!

best bottom paint AND not expensive
I have used Interlux, West Marine, Petit, ...This is the best ablative paint I've used and it is half the price of the other name brands
Been a boat owner for about 40 years and have done many bottom paints. My wife and I got our maintenance period mixed up and went three years with this bottom paint. We lifted the boat and found after a quick bottom wash that the paint was still doing well and could have likely gone another year. We live in a salt/freshwater mix and bottom growth is usually heavy, but not with this paint---it was the best result we've seen even with paint costing twice as much.
