Our Dock Boxes Offer Solutions To Common Dock Storage Problems

Haven Marine & Dock sells high-quality dock storage boxes designed to accentuate the appearance of your slip. Our functional and attractive specialty dock boxes are made from premium materials designed to withstand the rigors of marina use. Plus, each one is covered by a two-year manufacturer's warranty. 

No matter what storage problems you are experiencing, the high-quality dock boxes from Haven Dock & Marine can offer a solution.  

Removes Clutter From Docks

Our dock boxes help remove clutter from decking material. This dramatically improves marina safety and reduces the chance of someone tripping and getting injured as they approach your boat. Plus, the molded seat of our rectangular specialty box means you don't have to load your dock down with added furniture and accessories. 

As a result, investing in a specialty storage solution gives you a neat and attractive appearance every time you visit the marina. It can also free up space for some extra dock accessories to make life on the water easier and more enjoyable. 

Makes the Most of Wasted Space

Does your dock area have a few awkward corners that often go unused? A specialty storage box provides the perfect solution. Our triangular boxes fit into tight corners and curved spaces without impeding the flow of foot traffic or encroaching on furniture arrangements. 

Some boat owners are fortunate enough to have space for casual furniture arrangements. However, not all docks have the area to accommodate dedicated furniture. The compact footprint of our 51-inch dock boxes offers an ideal solution. They combine functional, secure storage space with a built-in seat that will accommodate most of your guests.
