Epoxy barrier coats?

The Tomcat cruises at 28-30 knots. At these speeds, the Micron CSC that I currently have ablates more rapidly at the water-air interface halfway back from the bow and also towards the back of the tunnel.

The epaint EP-ZO, designed for "powerboats with average operating speeds of greater than 30 knots" caught my eye. However, it requires "visible sunlight" to be effective. My boat is kept in the shade in a covered marina :shock:

Oh well!
 
Not sure where you saw that quote, Alok, but it’s not correct. The 2008 Technical Data Sheet for EP-ZO says it is recommended for “vessels with average operating speeds of 0-30 knots.”
 
Not a big deal, but this is directly from the company web site. The italics are mine.

Recommended Uses:
For marine and fresh water immersion service; for racing sailboats; powerboats with average operating speeds of greater than 30 knots; racers who want to obtain a hard, fast, sleek racing finish; for drag reduction and fuel savings; boats that are frequently hauled and launched by trailer

And from the data sheet:
Visible sunlight and oxygenated water are required for
ePaint antifouling and release coatings to work effectively.


Anyway, the operating speed was not my concern- I just did not know how effective the paint would be in my situation. My boat is kept in a covered dock out of direct sunlight. This, in combination with warm Texas water that promotes marine growth may reduce he effectiveness of epaint.

But I also don't know about "visible sunlight" in Washington State- I have heard that it rains there all the time :wink:

The question was, is there likely to be any wax to remove if the boat had been run for five years. It is not unusual for boats which are kept out of the water to have the bottom waxed, as the hull is waxed. I wax the part of my Tom Cat which is not on the bunk of the trailer.

I have considerable experience using two part LP paints, and the assumption is that hulls have always been waxed.

Alok: OK, I think I have this sorted out. The phrase you quote does indeed appear on the company’s web site (http://www.epaint.com/), but in reference to EP-ZO-HP, which (confusingly) is a different paint from EP-ZO. It is the high performance version designed for faster boats. I didn’t notice it myself -- that I was looking at the wrong page -- so I called the company (1-800-258-5998). Mike, a technical rep. set me straight, but he also said that the “greater than 30 knots” language -- even in reference to HP -- was misleading, not what they intended to say, and that he would take the reference out today.

He also addressed the “visible light” issue you raised. Again, he said the language used on the website and in brochures (written by sales people) was imprecise. Mike said he would address that one too. Meanwhile, he said, the technical data sheets, available at the website, are the best source of information on the paints.
