Big Air H2O.3 Tower

The H2O.3 is tried and true!
Starting our tower debut, the H2O.3 tower has been in production since the beginning. While over the years we have made small adjustments, this tower has stood the test of time.

The H2O.3 Tower is truly universal in that it can fit just about any boat and will mount on the top or the side of your boat. This tower comes standard in a brushed finish and accommodates boats 58 inches to 84 inches wide, perfect for those narrower hulls. You also don't have to worry about fitting the boat into your garage or storage area as the tower folds down and the front legs can be removed so that they do not stick up all in a matter of minutes.

Don't worry about stress cracking as our heim joint attachments in the mounts prevent this from happening. Our unique swivel system keeps the stress where it belongs, IN the tower.

  • Swivel Joint attachments on the base plates prevent stress cracking to your boats fiberglass. Many towers use a rigid mount, that delivers stress and flexure directly into your boats hull. This causes cracking and fatigue of the fiberglass. Our unique swivel system keeps the stress and flexure where it belongs, IN the tower.
