Know the enemy
Battling barnacles is the bane of boat owners everywhere because barnacle larvae are at the mercy of ocean tides and currents, and need to feed. But first they need a home, which is anything solid their little glue-spewing antennae can grab onto, including your boat bottom.
That insoluble glue spot welds the baby barnacle to your hull and gives off hormones that are the social medium that attracts other barnacles. Like barnacle Twitter. More bad news—while it feeds, the barnacle continues cementing its hold while building up the shell around it, which puts pressure on the hull. If not removed, eventually the pressure will deteriorate gelcoat or paint and may even penetrate the fiberglass beneath. It doesn’t take a PhD in barnacle biology to observe that barnacles reproduce and colonize quickly, so multiply that pressure times a million or so.
Settlement, metamorphosis, and growth to reproduction—it’s what barnacles do. Which is OK, except when they do it on the bottom of your boat, because more barnacles means more weight and drag on the hull, which means higher fuel costs and less ability to maneuver.
Get the enemy before it gets you
The trick is to coat the bottom with an antifouling paint that makes your hull uninhabitable for those biofouling miscreants that dwell in your particular harbor. At TotalBoat, we test all of our bottom paints in real-world settings and pass the best of what we discover on to you.
In recent tests, KeelHauler outperformed similar bottom paints in New England waters. Its self-polishing, ablative action means the paint erodes slowly from the surface as the boat moves through the water, revealing a biocide-rich paint layer to dispatch young barnacles and repel slime and algae before they can cling to your hull.
Discipline wasn’t taken lightly in the Age of Sail. As the captain of your ship, your word is law. Yes, keelhauling went out of practice a few centuries ago, but when your bottom is covered in barnacles, you may feel you’re being punished every time your bloody knuckles have to scrape them off. Or maybe you felt you’d been keelhauled after getting the barnacle removal bill from the boatyard. Be brutal. Give no quarter to barnacles and other biofoulers by coating your hull with KeelHauler. The more you use your boat, the more effective KeelHauler will be.
