CHARMED'S BOTTOM

Charmed was launched sixteen months ago with two coats of Pettit Ultima SR Ablative Bottom Paint, a blue signal coat, and a black finish coat.  The bottom remained clean in waters, New England to the Chesapeake to the Keys to Maine and back to the Chesapeake.  Almost no barnacles.  A little slime.  However, I wish a second black finish coat had been installed.  Even though there was little blue showing, there appeared to be thinning spots, probably as much from installation quality as from wear.  The water line wore well, even with a half dozen light brushings over the months to remove weed and other goo.

This week three gallons of black Ultima SR went on Charmed's bottom.  The three gallons covered one and three quarters coats.  Pettit's Quantity Calculator says three gallons should have gone two coats.  The paint was clean and easy to apply using a five gallon bucket and a paint screen that hangs over the edge of the bucket.  The Ultima is thick and likely goes on thicker than Pettit says is the one coat dry film thickness.

Charmed was painted at this point to make sure we keep a good bottom.  Now we think we might easily get two plus years before we must haul again to address the condition of the bottom.
