Custom made boat hardtops

If the regular size doesn't fit your boat, we are happy to produce your hardtop after your measurements.

Switching from bimini top to hardtop made easy.

We build our hardtop in a way to make it easier for you to set it up. If you already have a bimini top, you can replace the fabric and fix it on the underlying frame. In a short time, your boat is ready to go.

Please note we don't offer the support frame for the hardtop. The best way is to ask your local bimini top builder to make the framework.

Building a fiberglass hardtop

The hardtop is entirely made out of fiberglass, which makes it light enough to place it on your bimini top framework. Also, to stop the water flowing into the cockpit, we build a water channel into the hardtop.

The middle strip gives the roof more stiffness and can be used to place mobile solar panels or other small equipment. Safety always comes first -  to make your time on the boat as safe as possible; we integrate two handrails.
