Bottom Paint

I recently painted my boat with Blue Water Copper Pro SCX 67 Hard, having chosen the paint after reading that it was in the top of the list for several years in Practical Sailorís in the water test in Florida. My boat is in the St. Johns River in Jacksonville, Fla., and was launched Oct. 24. I have used the boat at least once a week. [In early December], I noticed slime starting to grow around the waterline. Needless to say, I was disappointed, especially after the PS test indicated no growth for well over a year, if I remember correctly. I thought I would be good at least until next summer.

Thanks for your feedback. Our testing takes place in Sarasota, Fla., so it is helpful to hear how the tested paints perform in other waters. Based on our findings, the Copper Pro SCX 67 Hard should repel barnacles for at least 18 months in your area, but you will see some algae growth after the first six months.

In our last test report, (PS, October 2012), we rated the SCX 67 Hard as Good after 20 months. This indicates the test panel had some algae/slime, but no hard growth. We also recommended it for long-term protection against hard growth.

Each published report on bottom paint testing includes an explanation of the rating system: no slime and no hard growth is Excellent; panels with some slime or algae are rated Good or Fair; and any panel with hard growth is rated Poor.
