Tall strapless bimini on a sail boat

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.

Perfect canvas in seconds every time


The strapless concept is flexible enough to suit a wide range
of bimini types and constructions.
The large frame in this clip has collapsible legs for easy storage,
but these are by no means standard or required for the design to work.

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).

Ordering is quick, easy and secure


Just choose the items you need and add them to your cart.

You can even leave your cart to do more shopping then check out any time you’re ready. To return to your cart, click the box at the far right of every page (the cart box is only visible after you have added items to your cart).

Best Mounts Period!

March 28, 2022

These are the best way we have found to mount solar panels and other accessories. These mounts work GREAT for mounting solar panels and accessories on any type of boat! They save us time and money for our customers and look great doing it!

Overall Good

Excellent product, a little pricey but they have it. Only downside was the import duty and taxes are not done at checkout so be prepared to pay for this.

We’re so glad you are happy with your mounts – we love photos if you care to show us how you used them. All the best and happy sailing.

How big a drill bit can I use?

can I use a 1/4″ dia bit?

Response from Gemini Marine Products

Thank you so much for the review. To answer your question, the DrillSteady is designed to take a 9/64 drill bit. If you need something larger, we recommend you use this as your guide hole. All the best and good luck!

Side rail mount

This worked perfect for attaching to our rail. We attached a stainless steel flag pole to it.

Great product.
