The Straight Line Sumo Sac will add 900 pounds of ballast to your boat. The Sumo Sacs are made with the most flexible and puncture proof materials.
The Sumo Sac has a sandwiched, woven polyester core and have internally glued and taped seams for a nearly indestructible bag. The sandwich construction keeps them thin, so they are easy to fold up and store when not in use. We spent a lot of time measuring different boats to make sure that these square bags will fit anywhere on any boat.
