Boat Covers for Hardtop/ Bimini Top

Hardtop Boat Covers

Protect your hardtop or bimini-top boat with a durable Southern Storm boat cover from The Cover Shop, available through Rockboat Marine. These semi-custom covers are designed for larger boats with raised hardtops or bimini structures and help protect your boat from New Zealand sun, rain, dirt and general weather exposure.

Southern Storm hardtop covers are made from marine-grade 600D solution-dyed polyester with a polyurethane coating for improved UV and water protection. The fabric is strong, breathable and well suited to regular outdoor marine use.

A useful feature of these covers is the side access zips, which make it easier to get into the boat without having to undo the rear of the cover.

Choose the Right Hardtop Boat Cover Size

Please measure your boat before ordering. Boat length alone should not be used to select your cover size.

Read our How to Size Your Boat Cover guide before choosing your size.

Measure your boat as shown in our sizing guide and add 0.3m to the measured length. If your measurement falls between two cover sizes, we recommend choosing the next size up.

Side zip position: Because hardtop position and boat design can vary between models, the access zips may not line up perfectly with the ideal entry position on every boat.

In some cases, the seam tape may lift or peel over time. This is a cosmetic issue only and does not affect the stitching, fit or normal performance of the cover.

Hardtop Boat Cover FAQs

What boats are these hardtop covers designed for?

Southern Storm hardtop covers are designed for boats with raised hardtops or bimini tops. Because hardtop height, width and position can vary between boats, always measure the complete boat profile before ordering.

How do I choose the right hardtop boat cover size?

Measure your boat using our sizing guide rather than relying on boat length alone. Use the actual cover dimensions as your main reference and add 0.3m to the measured boat length.

Are Southern Storm hardtop boat covers waterproof?

Southern Storm hardtop covers are designed to provide waterproof protection in normal weather conditions. The marine-grade 600D polyester fabric has a polyurethane coating to help keep rain out while the breathable construction allows moisture to escape from underneath the cover.

Why are side zips useful on a hardtop boat cover?

The side zips make it easier to access the boat without having to undo the rear of the cover. This is particularly useful on larger boats where getting underneath the cover can be awkward.

Will the side zips line up with the entry point on every boat?

Not necessarily. Hardtop position and boat layout vary between models, so the zips may not sit in the ideal access position on every boat.

Are these covers suitable for outdoor storage?

Yes. Southern Storm hardtop covers are designed for outdoor storage and provide UV and water protection for everyday exposure to sun, rain, dirt and general weather conditions.

Why is breathability important in a hardtop boat cover?

Hardtop boats can trap moisture around the cockpit and cabin area. A breathable cover helps moisture and condensation escape more easily and reduces moisture build-up underneath the cover.

Will the same size cover fit every hardtop boat of the same length?

No. Hardtop boats of the same length can vary significantly in beam, roof height, cabin shape, windscreen angle and deck layout. Always measure your boat before ordering.

Do the covers include tie-down straps?

Yes. Tie-down straps with quick-release buckles are included.
