Whether you're a weekend cruiser or a seasoned saltwater angler, we've got everything you need to get out on the water with confidence. Quality gear, honest advice — right here in Bay Shore.
Marine Barn Inc. has been a fixture on Degnon Boulevard, serving the Bay Shore community and boaters throughout Long Island. We started with a simple belief: every person who heads out on the water deserves access to quality marine products and straightforward, knowledgeable guidance.
We're not a big-box warehouse — we're your neighbors. When you walk through our doors, you'll find a curated selection of marine essentials, from navigation equipment and safety gear to fishing tackle and boat accessories. Every product we carry is chosen with the Long Island waterway in mind, because we know these waters the way we know our own backyard.
From routine maintenance to adventure-ready gear, browse our full range of marine products.
GPS chartplotters, fish finders, VHF radios, and compasses from leading marine electronics brands.
Life jackets, flares, fire extinguishers, first aid kits, and all Coast Guard-required safety gear.
Rods, reels, lures, line, and terminal tackle — everything for inshore and offshore saltwater fishing.
Covers, anchors, ropes, cleats, seating, and the hardware that keeps your boat running smoothly.
Antifouling paint, polishes, cleaners, engine care products, and winterization supplies.
Filters, spark plugs, propellers, fuel system parts, and replacement components for outboard and inboard engines.

Ask Us — We'll Source ItThere are plenty of places to buy marine supplies online. But when you need gear tomorrow morning — or you'd rather get it from someone who actually knows the water — you come to Marine Barn.
No automated chatbots here. Talk to people who've spent years on the water and can help you pick the right product for your specific needs.
We carry brands we trust and products we'd use ourselves. That means less time sifting through junk and more time getting what works.
Walk in, browse at your pace, and walk out with exactly what you need. No shipping delays, no guessing about fit or compatibility.
"Marine Barn is my go-to whenever I need something for the boat. George and the team always know exactly what I need, even when I can't quite explain it myself. Great selection and fair prices."
"Stopped in last season needing a new anchor line and some safety gear. They walked me through everything I needed for my boat size and the trip I was planning. Honest advice — that's rare these days."
"Best marine supply store on Long Island, hands down. They special-order anything they don't have in stock, and they always follow up to make sure it arrived and fits. That's the kind of service you don't find everywhere."
We're located right on Degnon Boulevard in the heart of Bay Shore — easy to find, easy to park, and ready to help.
