The Fly High w706 Pro X Series Open Bow Sac 1000lbs is triangular in shape and fits open bow boats. Place it up front and fill it for a huge improvement in wake transition and density. The shape of this sac allows the ability to fine-tune the forward and aft weight distribution.
The w706 Pro X Series Open Bow Sac 1000lbs is triangular in shape and is designed to completely fill the open bow area. Place it up front and fill it for a huge improvement in wake transition and density. The shape of this bag allows the ability to fine-tune the forward weight distribution by partially filling.
This bag adds a lot of weight, so it should only be used if you have an equal amount of weight in the back of the boat. In conjunction with more weight in the rear, adding 1,000lbs. of weight to the front of the boat will make the wake more ramped with a longer and smoother transition. It will also make the boat easier to drive and more responsive in turns and double ups.
