The Escalating Battle Against Biofouling

For as long as humans have sailed the oceans, marine growth on hulls has been a stubborn adversary. Thi acculation of barnacles, algae, slime, and extraing organisms - collectively known as biofouling - creats unduse drag, reducing a vessel 's speed up to 10% and extraing fuel consumption by as much as 40% if left unchecked.

Anti- fouling coatings are primary line of defense, designed to prevent organisms from attaching to submerged surfaces. For decades, the industry relied on potent biocidal paints that slowly leached toxins like tributyltin (TBT), copper, and tell tour blavy metals.
