Used to help support cover and keep from pooling water.
Info from manufacture:
The easiest most cost-effective way to
extend the life of your boat cover. Eliminates virtually all possible
areas that could collect water and allow it to pool, causing damage to
the cover. This system is designed for simplicity with two
pre-installed, adjustable 20-foot straps that snap quickly to the rear
tow hooks and one 40-foot adjustable strap to cradle the bow. System
fits up to 28-foot boats. For pontoon boats, two systems are required
and can easily be joined to create a perfect "frame" for the boat cover.
Each system comes with one adjustable (40" to 70") support pole, system
center, strap set and simple installation instructions. Order No.
