The Oceansouth Boat Seat Boxes with Waterproof Storage Hatch deliver a smart combination of strength, practicality and style. Built from UV-treated, marine-grade ABS plastic, these seat boxes are engineered to withstand years of exposure to sun, saltwater and heavy use. Their heavy-duty construction, combined with stainless-steel hardware and a watertight seal, ensures reliable performance while protecting your gear from the elements.

Beyond durability, these seat boxes provide genuine functionality on board. The integrated waterproof hatch and compartment offers a safe, dry place to stow fishing tackle, personal flotation devices (PFDs), tools, keys, phones and safety essentials, while the smooth, clean white finish and subtle taper give the boxes a sleek, professional appearance. Available in two heights to suit different deck layouts, they are designed for easy installation and compatibility with Oceansouth boat seats, as well as most other seating systems.

Whether used as a primary seating base or as an upgrade to add secure waterproof storage, Oceansouth’s Boat Seat Boxes are a dependable choice for boat owners looking to maximise space, comfort and protection on the water.

With their robust marine-grade construction, integrated watertight storage, and versatile seating compatibility, the Oceansouth Boat Seat Boxes offer boaters the perfect combination of seating comfort and practical storage.
