Got these for my boyfriend to go on his gas powered bike to do DoorDash delivery. These work great for the task no more spilling drinks

These are perfect for our sailboat. Easily attach to bimini pole or rail. I worried it might not be able to hold a can or bottle with a coozie and if it did, it’d be hard to remove from the holder but that is not the case. Holds cans, bottles, etc firmly but easy to remove. These are just perfect. You’ll likely be as pleased as I am!

These are pretty cheaply made but do clamp on to any boat rail. They serve their purpose but doing it again I prefer metal versions. I pull these out when we have lots of company on boat.

We have been having issues on tripping over each others drink containers because we removed the table on the back deck. These cup holders fit perfectly on our bimini rails, making our deck cleaner and safer. They were easy to install.

Es estable, le falta estructura para que dure más

Any boat owner will tell you there's never enough cup holders. These are exactly what they look like and work great. Worked well with cans, tall cans, and big tall boys and normal sized cups. It doesnt really fit larger 30oz+ tumblers (which is sad because its my go-to) but its not a deal breaker. These are just meant to be supplemental, and the best part is you don't have to pick a permanent location to install it because they just unclamp and move to your next preferred beverage location. For $15 I can't think of a more effective addition to your boat. They are not large enough to clamp around larger poles like T-Top supports, but work fine for bimini and hand railings. Like one user mentioned they are slightly a pain on regular short cans because the holder is taller than the can, but only a minor gripe. Great value for the cost.

Ok. Cheaper feeling, comes off once you go to take can out. Holds cups in good while boats going so not too bad
Reviewed in the United States on December 5, 2025 by danielle giannini
I own an older boat that doesn't have many cup holders. The one nearest to my seat (I'm the first mate!!) isn't in a convenient location for me, so I was very excited to try these cup holders out. First of all, they come two in a box which is nice and they are SUPER easy to install. If you can turn a knob or screw, you can install this cup holder in literally seconds. Mine is installed on the bimini top rail closest to where I sit. It's also very easy to reposition or completely take the holder off. The part that holds your beverage is able to rotate so that the drink stays parallel, and it doesn't matter if the rail you attach it on is slanted or horizontal. I was worried that it might rotate too easily, which would make the drink slosh around, but it doesn't. Once you have the holder part tilted the way you like, it pretty much stays in place. Besides the easy installation (and the fact that it can be easily moved or repositioned) what I really like about this drink holder is that it expands to hold a drink in a "wider" cup, and it easily closes back around a narrower cup/can. This weekend I tested it out with a slim can, a 16 oz. water bottle, a standard sized can, and a wider plastic cup. All easily fit into the cup holder and all were kept secure without any spills. The only complaint I have, and it's VERY, VERY minor, is that when I had my can of root beer in the cup holder, it sat down low into it and it was SLIGHTLY harder to remove because you have to grab it from the can lip. I kept finding myself wanting to push the can up from the bottom of the cup holder--- but you can't because the bottom that the can rests on is solid. I wish there was a small hole (wide enough for a finger) so that I could push the can up higher so removal would be easier. For the price, ease of installation, and convenience, these cup holders are great. They fit around the bimini top rails and I could see them being used in other places, other than boats!
