Bimini conversion kits
Everything you need to go strapless today
It’s your bimini. Just better.
Eliminating those pesky straps would clear deck space, open your cockpit and give you freedom to move, fish and access more of your boat more easily. Winches would be clear, companionways open.
Enter the strapless bimini.
Struts, not straps, push open the frame and hold it firm until you take it down, giving you perfectly-tensioned canvas every time with nothing to adjust (and no pins, straps or hardware to lose).

Strapless bimini conversion kits
Upgrade your canvas – we’ll make it easy.
Our DIY bimini conversion kit transforms the bimini you already have into a sleek strapless version quickly and easily.
You want:
- Sun protection that doesn’t compromise
- Clean, smart styling for your boat with maximum space on board with minimum fuss
- Great value
With our conversion kit you get:
- 2 x patented GemLock folding struts (available in 3′ or 6′ lengths, just cut to size and install)
- 4 x rail mounts (your choice of our sliding OR split side mounts)
- 4 x eye ends in the same size as your chosen tubing
- All kits are priced at a discount on buying the components separately
Kits are available with 7/8” (22mm) or 1” (25mm) tubing. All components are made from marine-grade 316 stainless steel for years of trouble-free use.
Suitable for all kinds of boats, if you have a bimini, it’s time to go strapless. One kit will convert your bimini.


Can I convert the bimini on my power boat to strapless?
Yes you can, but the system is not designed to bear the heavy loads generated when travelling at speed. A few extra steps will help keep you safe.
We strongly advise folding up frames while underway (or trailering on the road). This prevents damage to your canvas, hardware, deck, etc. Our canvas shop regularly makes repairs for customers who regret trying to leave a bimini up while underway or on the road. The strapless system makes taking down canvas very quick and simple because it is so easy to deploy.
If you cannot take down the canvas while travelling at speed, please take the following precautions when installing your strapless bimini:
- Use a pair of forward straps to control the load on the forward cantilevered edge and prevent it flying up (and breaking/tearing components). These can be removed when the boat slows.
- Any set screws in the frame’s lower connections should be replaced with screws mounted through the eye end and into the tubing to make the fittings secure.
- Secure the deck mounts with through-bolts (not simply screws into the fiberglass).

Great Quality
I have not used at this time for the original intended purpose. I will keep the clamps for future use.

Stainless steel hinge
These were not round.
Had to take them to machine shop and have them turned to fit. The shank on them is not .065. Closer to .875. Being they were larger and out of round. They had to be turned.
Luckily I work for a large airline and was able to take them to work.
Response from Gemini Marine Products
Thank you for this feedback. To help clarify: The description for this item clearly states, “Size: 1″ stainless steel hinge for use with .065″ wall thickness stainless steel tubing” – the insert portion of the hinge is not .065″. That is the wall thickness of the stainless tubing for which is it designed to be used. While it is possible it was out of round, the hinge is purposely designed to be slightly small for 1″ x .065 tubing, and the 0-ring is intended to compensate for any distortions in either the hinge casting or the tubing. We’re sorry this confusion caused you extra work, but we’re very happy you like them.
