Dock Boxes FAQs
What materials are your boat dock boxes made from - fiberglass, plastic, or aluminum?
Dock boxes are constructed from durable materials like fiberglass that can endure harsh marine environments. Residential and commercial waterfront projects of any size rely on a dock box fiberglass construction for its strength, weather-resistant, and long-lasting performance.
What sizes of boat storage boxes does Dock Boxes Unlimited carry?
We have a variety of sizes available for different uses like life jackets, ropes, larger boating accessories, and equipment. Whether you need a compact boat storage box or a larger solution for extensive gear storage, you’ll find options to suit your needs.
Are your dock boxes weatherproof and UV-resistant for outdoor marine use?
Yes. Made to withstand all kinds of weather conditions outside throughout the year, our boat storage containers are waterproof and resistant to any form of humidity. Your boat accessories and personal items will remain completely safe from adverse climatic effects.
What is the difference between a dock box and a boat storage container?
A dock box is a storage space for marine use, and is most often placed on a dock or marina. The term boat storage container is a more inclusive term that can be used to describe a variety of storage products used to organize and protect boating equipment. Generally, boat dock boxes used in waterfront applications are constructed with more weather resistance and security.
Can dock boxes be secured or locked to prevent theft at a marina?
Yes. Many models include provisions for locks, allowing you to secure your gear when the box is unattended. A locking boat dock box can provide added peace of mind in shared marina environments.
Do you offer dock boxes for sale for both residential docks and commercial marinas?
Absolutely. We have dock boxes available for sale in different models and for several uses, such as private waterfronts, yachting clubs, and even commercial marinas. There is sure to be a size and model that meets your needs.
How do I choose the right dock box size for my boating gear and equipment?
It is important to think about the amount of gear that will need to be stored and how much space is available at the dock when purchasing a dock box. It would make sense to purchase a large one if it is intended for storage of safety, water sports, and other maintenance equipment, while smaller boxes are suitable for daily use.
