The Fly High w706 Pro X Series Open Bow Sac 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. Bringing the bow down lengthens your wake for that longer ramp up you need as a bigger surfer or for bigger tricks and more air.
The Fly High w706 Pro X Series Open Bow Sac adds up to 1000lbs to the front of your boat, so it should only be used if you have a lot of weight in the rear of your boat such as our W707 750lb sacs or our w719 jumbo surf sacs with 1100lbs in each rear compartment. In conjunction with more weight in the rear, adding 1,000lbs. of weight to the front of the boat will make the wake longer with greater push. It will also make the boat easier to drive, and more responsive in turns and double ups.
