Finn Dock Boxes: Strength Proven in Tests

Our dock boxes at Finn are super strong. Why? Because we make them from top-quality fiberglass, a material that is really tough.

We like to show how strong our dock boxes are. So, we carry out a special ‘load-bearing test’. In this test, we have four people stand on the lid of the dock box. This test helps us to show that our dock boxes can handle heavy weight and lots of pressure, just like they might face at a busy dock.

Our dock boxes pass this test with flying colors! They hold up really well, proving they’re tough and can keep your stuff safe. So, with Finn’s dock boxes, you’re not just getting storage. You’re getting a strong, long-lasting piece of equipment for your boat.

Fiberglass vs Polyethylene Dock Boxes

When it comes to dock boxes, the material matters. The two common materials used are fiberglass and polyethylene. Let’s compare these materials and see why fiberglass, as used in Finn’s dock boxes, stands out.

Strength: Both fiberglass and polyethylene have commendable strength. However, fiberglass tends to have a superior strength-to-weight ratio, making it a robust yet lightweight solution for dock boxes. This means Finn’s fiberglass dock boxes can handle substantial loads without the box itself being heavy.

Maintenance: Polyethylene dock boxes can resist a fair share of environmental wear and tear, but they can eventually show signs of aging like color fading. Fiberglass, on the other hand, requires minimal maintenance and retains its appearance for longer, thanks to UV inhibitors that protect against sun damage. Our dock boxes remain bright and attractive, even after prolonged exposure to the sun.

Appearance: Fiberglass offers a smoother, more polished finish compared to polyethylene. This means that Finn’s fiberglass dock boxes not only perform well but also look sleek and premium.

At Finn, we boast a team of skilled craftsmen and a fully-equipped production facility to deliver a broad range of customization and design services for your fiberglass dock boxes. Here are some of the processes we specialize in:

Molded Designs: We employ state-of-the-art molding techniques to create intricate and unique designs, perfect for showcasing company logos, names, and locations. This involves manipulating the fiberglass material to form distinct patterns or characters on the surface of the dock box.

Custom Logo: Our custom service allows for the etching of characters into the fiberglass. This is ideal for marking serial numbers or other variable information on your dock box, providing an extra level of customization.


Painted Designs: We offer fully customized painted dock boxes for those looking for an extra splash of color. This service allows for the creation of elegant and multicolored designs that truly make your dock box stand out.

In addition to these, we also offer a range of other customization options, including different sizes, shapes, and even different types of locks and hinges. At Finn, we believe in offering a truly personalized product that caters to the unique needs of every customer.
