Deck Box - DB320

DB320 Heavy-Duty Marine Deck Box – 320L

Built tough for life on the water. Designed for more.

Make the most of your deck space with the DB320, a spacious, heavy-duty marine storage box engineered to withstand demanding marine environments. With a generous 320-litre capacity, it offers ample room for fenders, ropes, deck equipment and essential nautical gear, helping keep your boat organised, clutter-free and ready for action.

Exceptional durability meets reliable protection. Laminated and constructed from robust glass-reinforced plastic (GRP) in our workshop in Middlewich, the DB320 is built to handle harsh marine conditions. Stainless steel hinges and latches provide dependable strength and secure closure, while the intelligently designed lid overlaps an internally moulded lip to help prevent water ingress and protect your equipment from salt spray and moisture. Its durable construction also offers resistance to UV exposure, making it ideal for life outdoors.

More than just a storage box. Larger than many conventional deck boxes, the DB320 offers valuable extra space and versatility. Its reinforced lid doubles as a practical work surface, supporting up to 100kg of evenly distributed weight when closed. Whether you need a convenient surface for maintenance tasks, equipment preparation or everyday jobs, this clever dual-purpose design makes every inch count.

With its generous capacity, rugged construction and practical work-surface functionality, the DB320 is a smart storage solution for both onboard and shoreside use.

Manufactured in white as standard, however if you require a custom RAL colour, please contact us to discuss.
