If you’re not a boater there’s no shame in not knowing what a sacrificial anode is. But if you are a boater, you know there’s no way your boat would go in the water without them.
Corrosion is a boat’s worst nightmare. And if you remember your high school chemistry, you know that the salt water that surrounds us here on Long Island plays a big role in electrolysis. We’ll save you most of the chemistry-speak, but the bottom line is that with all the different metals attached to your boat, the chance for electrolysis (corrosion) is present. Since zinc is one of the least noble metals (hey, I said we’d save you most of the chemistry-speak), it sacrifices itself in an effort to preserve your expensive running gear and propellers (hence the term “sacrificial anode”). Using inexpensive and replaceable anodes helps to ensure your boat remains fully intact.
In a sea of competition (get it?) – mostly made up of cheap, die-cast zinc and aluminum anodes manufactured in China – B&S has found a way to stick out against the crowd by offering high-quality at a good price. As a local, family-owned-and-operated manufacturer, they’re able to control the manufacturing process and produce hand-poured anodes. According to owner Krista Wicklund, “Hand-poured zincs have a higher degree of porosity than die-cast zinc, allowing for a greater surface area exposed to the water for corrosion.”
Don’t care to take her word for it? B&S just signed an agreement to move from their current facility in Bellport to a new facility in Yaphank that will double the size of their production and warehouse space. It seems the consumers have spoken.
