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.

It’s a good time taking your sons fishing. It’s less of a good time when you are taking your sons fishing and the game warden asks to see your life jackets. It’s REALLY NOT a good time when the game warden gets pissed because all you have is two horse collars and a strawberry shortcake lifejacket after your expensive self inflating life jackets went off two days earlier because my trash boat cover set up let them get soaked during a storm. Get a SwellUP, keep game wardens happy, and avoid having to wear wet mildew covered strawberry shortcake life jackets. Easy to set up. Keeps the boat dry and airs it out. Great stuff!
