Antifouling boat paint can overcome
rising fuel costs
Boats with fouled bottoms can use as much as 10% more fuel. This means
that now, more than ever, you need to employ the technology that racing
sailboats have been using for years: antifouling, non-stick, copper/Teflon
boat bottom paint. These easy-to-apply bottom paints, or bottom coatings,
can save every boat owner money.
non-stick, racing-type boat bottom paints work:
- To produce smooth hulls, racing-type
boat bottom paints use the same molecule contained in non-stick
cookware, the largest molecule known, with a drag coefficient smoother
- Copper is often embedded in these fast
Teflon-type coatings, causing barnacles, zebra mussels, algae, and other
water growths to reject them and seldom attach themselves to your
- These coatings slough off like a bar of
soap, taking growth away with them as water passes over the hull,
keeping the boat bottoms smooth.
A few negative aspects to using non-stick,
racing-boat bottom coatings:
- The boat bottom requires recoating
every few years as the finish wears away.
- Sanding is needed every few years so
the next coating will adhere well.
- The boat bottom color will darken as
the copper oxidizes, turning a dark brown/gray.
Cost may not be a major factor. A 20- to
30-ft. boat can be coated for under $100 in materials. Not a bad price to
pay for a 10% savings in fuel costs.
Protecting your boat bottom from growths also helps maintain the value
of your boat. In years gone by, ship hulls allowed for rusting to wear
away 2/3 of the steel over the life of the ship. But today, with
urethane Teflon-type bottom coatings, ships can go 11 or 12 years
without recoating or loss of steel thickness. In the 70s, the U.S.
Navy tested these non-stick coatings on five ships and were impressed
that residual growths that had not come off after speeds of 10 to 15
knots were reached could be removed with simple pressure washing. This
eliminated grinding and the associated hull wear.
