OS Marine

O’Sullivan’s Marine is one of Ireland’s most established and trusted marine businesses, proudly trading since 1963. Based in County Kerry, we began by crafting our own range of OSM fibreglass boats, a tradition we proudly continue today. Our high-quality boats—built for lake, sea, and river use—feature heavy-duty, hand-laminated fibreglass hulls and can be custom-fitted to your exact specifications. From the compact 9’6” Suir to the 20ft Seamrog Cruiser, every OSM boat reflects superior craftsmanship and Irish heritage.

Over the decades, we’ve grown into one of Ireland’s leading suppliers of marine products, representing world-renowned brands and offering everything the modern boater needs. We are main agents for Linder Aluminium Boats, Whaly Boats, and Cool Kayaks, and stock the largest selection of RIBs and inflatables in Ireland, including Gladiator, OSM RIBs, and OSM Inflatables—all at unbeatable prices.

Our extensive inventory also includes outboard and inboard engines from leading brands such as Tohatsu, Suzuki, Yamaha, Honda, Yanmar, and Sole Diesel, as well as trailers from Snipe, Extreme, and SBS. In addition, our 30,000 sq. ft. facility houses thousands of chandlery products—from marine electronics and paints to safety gear and specialist fittings—from top names like Garmin, Raymarine, Lalizas, Nuova Rade, Ocean Fenders, and more.

At O’Sullivan’s Marine, our experienced team combines decades of expertise in sales, repairs, and custom boat fitting. We specialize in complete boat packages, including the boat, engine, trailer, and safety equipment—professionally fitted to your needs. Our commitment to quality, service, and unbeatable value makes us the go-to choice for marine enthusiasts across Ireland.

For all your boating, marine, and chandlery needs, look no further than O’Sullivan’s Marine—where tradition, innovation, and value sail together.
