Key Features:
- Inflatable Design: SwellUp’s unique inflatable structure evenly tightens your boat cover, preventing water pooling and ensuring a secure fit.
- Adaptable fit: From 24″ up to 72″— SwellUp adjusts to your boat’s shape, eliminating the need for perfect positioning. 6 Zipper vents allow you to adjust the height, shape, and airflow of SwellUp.
- Air Circulation: Continuous airflow helps prevent mold and mildew, keeping your boat fresh and dry.
- Pest Deterrent: Subtle vibration, airflow, and a eucalyptus-peppermint scent help repel common pests like wasps, mice, and spiders.
- Durable Construction: Built to withstand all weather conditions, Swell protects your cover from rips and tears.
- Magnetic Centering: SwellUp comes equipped with a built-in magnet at the top of the inflatable sphere and includes a second magnet for use on top of your cover. Simply place the free magnet on the outside of your boat cover and guide Swell’s internal magnet to connect from underneath. This ensures perfect centering for inflation every time. When it’s time to remove, it’s just as easy. No guesswork, no hassle—just perfectly aligned protection.
- Multi-Functionality: SwellUp prevents water pooling, constantly circulates air,, and deters pests—offering complete protection for your boat cover.
- Power Outages: If you lose power, SwellUp goes down with it. But don’t worry—Batten Down is working on a UPS (Uninterrupted Power Supply) that will use your boat’s battery to seamlessly switch power sources during an outage. Until then, there are plenty of backup power options available from other online vendors to keep you covered.

Swell is so much easier and faster than any pole tensioning systems, both for setting up and putting away! I assumed it would take awhile to inflate, but it’s super fast. Even though it costs more than the pole systems, it’s worth every penny and you won’t regret it!

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.
