An upper deck is not a bimini canopy, nor is it a regular sun shade. It is not a sun deck per say, and it is not a roof.
An upper deck actually
adds a second level to your boat.
Yes, that means your little 8ft pontoon boat just turned valuable when you built a do it yourself upper deck kit by j's upper decks, on it.
The Upper deck is also not a temporary structure like a bimini canopy or another top would be. This is an aluminum built deck. You can stand on it, ride on it, walk all over it and sun bathe. Or go wild and crazy and use it as a dancing platform. It is that sturdy.
even though an upper deck does the same thing a bimini canopy, a sun shade and any other temporary top for pontoon boats does-----it’s nothing like them.
So don’t think of an upper deck as an alternative to a bimini canopy, think of it as sooo much more.
