Ultimate Wake Surf Sac (W718).Love wakesurfing? Want to get the best possible wake out of your boat? Buy this ballast bag! We don't call it the Ultimate Wake Surf Sac just because it sounds cool, whether you've got a direct drive or a v-drive, this bag combined with a standard surfing setup will transform your wake. The new Fly High Pro X Series Ultimate Wake Surf Sac is bigger than ever to create the perfect wakesurfing wake. Equally at home in inboard, v-drive and even jet boats like the Sea-Doo AR and Yamaha Wake Series, this is what you need to go ropeless the easy way. For Direct Drive Boats Position this bag in the back corner of the boat for 1,000 pounds of wake building ballast. And since it's a single bag, it will be faster to fill and drain than multiple bags that weigh the same amount.

The wake will grow in size, and you won't lose any seats inside the boat. You don't need a v-drive to put out a great surfing wake, you just need the Fly High Pro X Series Ultimate Surf Sac.
