Easy speed upgrade. Your gelcoat needs you.....to keep it clean and protected from the sun.

Gelcoat is plastic and degrades with exposure to sun and chemicals in the water. A clean well maintained hull will be faster and last longer. Clean your hull at least twice a year and regularly rinse it. Give it a good coat or two of UV wax once of twice a year. Probably the quickest and cheapest performance upgrade for your boat.
