FatSac C1039 Yamaha Jet Boat 24ft Custom 800 lb Ballast Bag with Fittings

The FatSac C1039 is a semi-custom 800-pound ballast bag engineered specifically for 24-foot Yamaha Jet Boats. Designed to mount to the swim platform step at the rear of the boat, this ballast bag adds significant weight to the stern, creating larger, surf-ready wakes ideal for wakesurfing and wakeboarding.

Constructed in the USA using advanced welding techniques and high-quality rafting material, FatSac ballast bags are trusted by leading boat manufacturers and water sports enthusiasts alike. The C1039 arrives complete with all necessary fittings—no additional hardware required.
