After eight years in sailboat rigging, I kept running into the same problem: Marathon needed a real boat-parts store. You could find plenty of shirts and shoes around town—but not always the parts needed to keep a boat on the water.
So, in 2024, I decided to build the kind of store I wished we had. In 2025, we found our home on Overseas Highway, opened the doors, and the fun began.
Today, Onboard Marine Goods is powered by an eclectic crew of local boat people, problem-solvers, and genuine Keys characters. We have firsthand experience with the products we sell, and we’re always ready to help—without the runaround.
Come talk boats with us. We’ll help you find the right part, share what we know, and probably make you smile along the way.
