Pretty happy with this system. New boat owner here, and this seemed like the obvious choice when looking at all the options available. Couldn’t find many high rating reviews for the support poles. Straightforward to use and glad I don’t have to go through all the struggles I read others going through. I like that it does more than just tension the cover too.

I have been dealing with Boat Cover Support systems for over 50 years and this is by far 100% the best. It can be installed in less than a minute. I’ve had mine installed for over five months now and no evidence of mildew, insects or rodents. Without a doubt, the best accessory I’ve ever bought for any of my boats throughout the years.

I love the ease of use of this cover tensioner. Just put it in position and plug it in. Works perfectly with my boat and fitted cover. No more bailing water off my cover or out of the boat when storing it. 5 stars

I’m so glad I bought this inflatable, cover tensioner. It has completely solved the problem of water pooling on my cover and musty smells when left covered for a long time. As a bonus, it keeps pests like mice and wasps from getting underneath. I haven’t had any wasp nest issues since installing it, which is a massive relief. It’s sturdy, easy to use, and has held up through several storms. Would recommend it.

After dealing with water pooling and an invasion of wasps under my boat cover, I decided to try this cover tensioner… It works. My cover now stays tight, no poles that can tip over. Noticeable decrease in wasps and haven’t noticed any mice.  It was easy to use, and the peace of mind it provides is invaluable. If you want to protect your boat from water and pests, this is the product for you.

This inflatable is amazing! It keeps my boat cover tight, so there’s no water buildup, and it also acts as a barrier against pests. I used to find wasps nesting under the cover and mice trying to tear up my seats, but not anymore. It’s like having a dual layer of protection for my boat. The product is durable, easy to install, and has made maintaining my boat so much simpler. It’s worth every cent.

This little unit has exceeded my expectations so far. Batten Down’s Swell, is not like the blow up Halloween decorations. It is crazy powerful. I have a heavy sunbrella cover and it holds it up with the fan at less than 1/4 power with all straps cinched down. Should help with airflow to prevent mildew and mold. Look forward to checking it in a month or so. Nice work!

This thing has been an absolute game-changer. Not only does it keep my boat cover tight and free of rainwater, but it also prevents pests like mice and wasps from setting up shop inside. I’ve noticed a huge decrease of wasps in my boat since installing this tensioner. Installation was quick and easy. Highly recommended.

This undercover inflatable is a lifesaver. Before using it, my boat cover would always sag and collect water after any rain. Now, the cover stays tight and dry, even during heavy downpours. It was easy to install, and the quality is good. I’ve had it for a few months now, and it’s still going strong. Love the constant air circulation and fresh smell it keeps. This is a must-have accessory for anyone who wants to keep their boat and cover in top shape!

I’ve been dealing with rainwater puddling on my boat cover for years. After trying several DIY fixes, I decided to give this inflatable thing a try. Yeah, worth it! It’s easy to install and does exactly what it’s supposed to. My cover stays taut, and I haven’t had any issues since I started using it. It’s made boat maintenance so much easier, and I’d recommend it to any boat owner. Side note, pest deterrent is a big plus.
