Regardless of how old an anti fouling paint is or how well it may have worked at any time during its lifespan, hard growth does not simply "wash off", at least not without a pressure washer. If that is actually a criteria of the Practical Sailor anti fouling paint tests (and I doubt that it is), it is an unrealistic one.

Re: Seahawk Bottom Paint - **UCKS!

Using Micron 66. There have been numerous changes in formulations in most all brands with resultant poorer performace. Bought extra micron 2 1/2 years ago. Kept unopened in very cool place. Also was given packets of a tin additive. So far so good. Problem has been running gear and bow thruster. Nothing works. So run the bow thruster at anchor time to time. Think most important thing for any ablative paint is to sail the boat. From what Iíve seen and heard the water based paints are worthless, black and red are better than white or light blue with ablative and nothing prevents slime if the boat is still.

Just some good-natured jocularity. Pay no never mind.

A couple quick comments on that, they are paints that use water as a solvent and not water based. We have been getting really good feed back on the water soluble paints. It is my understanding that they tend to carry and disburse the antibiotic based anti-fouling (SR) materials better than their alkyd cousins. Also for what its worth, it is my understanding adding tin to bottom paint (except for very specific excepted cases) is illegal in the U.S. and Europe since its adding a heavy metal to the water. In terms of color, according to the paint manufacturers Black does the worst of all bottom paint colors. Red is often thought to do best since the manufacturers can add more copper without it showing and so you could only buy the highest copper content material in red. Now a days you can buy blue or green with the same copper content and they perform about the same as red. White is specialty color that does not conceal as large a copper content and so does not fair as well because there is generally less copper in it. But because it is white, you are also more aware of any fouling so the racers liked to use it since the divers could in theory do a better job because they could better see what they were doing.

Re: Seahawk Bottom Paint - **UCKS!

When we sailed on Barnegat Bay I started out with Interlux ablative because that's what the yard used when we bought her. We got three years out of it for six years total.

I tried Petrit Hydrocoat and got three years out of it as well. When we hauled out the second season it was showing a little more wear around the water line and leading edges than the Interlux so I touched it up.

The last year I had that boat I tried Sea Hawk at the recommendation of a local shop. I was shocked at how bad it was after one short season where the boat didn't even get all that much use. The hull needed to be completely redone after one season.

I would never use Sea Hawk products again.

The prep and application was the same for all three paints. The bottom was pressure washed when we hauled. The old paint was scuffed with a sanding screen, then washed to remove the dust. Two coats of paint on the hull, and a third coat along the water line and the leading edges of the bow and keel.

Currently Boatless

ďThe sail, the play of its pulse so like our own lives: so thin and yet so full of life, so noiseless when it labors hardest, so noisy and impatient when least effective." - Henry David Thoreau

The latest email for the Seahawk rep:

"
Ray Surdyk
5:43 PM (1 hour ago)
So you donít clean your hull on a monthly basis?"

You can see where this is going. Guess it means nothing to them that this was new paint mid Feb. Left mostly fresh brackish water Mar 8 with a clean hull. STILL had a clean hull in Palm Beach on 4/5. On 4/15, 1/3 of the boat had hard growth.
