Designed specifically for Yamaha Jet Boats - The 725 lbs FatSac Ballast Bag is shaped and sized for 2017 and newer 21' Yamaha Jet Boats. The FatSac Ballast Bag is designed to rest on the rear swim platform and step with integrated handles for strapping the bag to the rear cleats and lifting eyes.
Although Wake Shapers alone aren't the answer for Jet Boats and the difficult wash out. Combining the NautiCurl Flex Wake Shaper to assist with diverting the water along the non-surf side and listing the boat with rear transom ballast, you'll be surfing in no time!
