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).

as always, your products are top shelf – again I removed the set screw and drilled it out for a bolt
Response from Gemini Marine Products
Always happy to make folks happy. We’re so glad they are working well for you.

used the fittings to install a storage box between my dinghy davits – all the fittings worked perfectly – I did drill out the set screws and installed bolts to prevent failure
Response from Gemini Marine Products
Hello there Mr A, So glad to hear these worked out for you. Thanks also for the tip on a new use for our hinges – we’re always super happy to share all the ways our hardware can help on board. All the best for now and happy sailing.
Very happy with purchase
the mounts look great on the arch of our sailboat, holding my solar panels! Easy to set in place. Will buy again when time comes for more panels.

Thank you so much for the feedback – we’re so glad they worked for you, and we look forward to serving you again.
High quality and shipped very quickly.
I’d prefer a product that doesn’t exist yet: curved, fixed length grab rails with swiveled, hinged clamps that don’t require committing to drilled holes in my dodger frame, like studded grab rails do. Gemini should make this!
But these side rail mounts seem like they will work well instead, and price and shipping were better than Sailrite. The stainless casting and finish is perfect quality. I was worried they would not slide over curved tubing, but there is just enough clearance to do so with no problem.
Response from Gemini Marine Products
We’re so pleased they did the job for you. Great idea for grabs, too.
Great Service from Gemini
Great service from Gemini from my on-line order placed from Australia. Parts were shipped quickly and lots of feedback from them as to what was happening. DHL air freight let them down with their service though as the 4 -5 days transit turned into 2 weeks as the parts went on a worldwide tour (no reflection on Gemini, they were as frustrated as I was). Very happy with the mounts and will have them and my new solar panels on the yacht in the next week or so.
Response from Gemini Marine Products
Aw thanks Mr W for the kind words and being understanding about the shipping problems we faced. You bet we were frustrated for you! We’re so happy the mounts will work for you. Happy sailing.
Nice product
It is a good product and fit correctly on the rail. However check the screw threads one did not seat completely but that was a small problem.
Response from Gemini Marine Products
Thanks for the kind words and the feedback – we will do as you suggest.
