Sumo Open Bow 500



The medium sized Straight Line Sumo Open Bow Ballast Bag gives you 500 extra lbs. of weight hidden in the bow of your boat.

The Sumo Open Bow Bags are a popular option to help keep your boat level loaded for better performance while surfing and wakeboarding. This medium sized open bow sac is designed to fit underneath the seats of most 19 to 21-foot boats with under seat storage in the bow. It will be out of the way to maintain bow seating availability. All Straight Line bags come standard with 1″ NPT ports (1 LINK fill, 2 fill/vent, and 2 drain) and are compatible with our factory ballast upgrades and Straight Line’s Sumo and Super Sumo pump lines.

Straight Line Ballast Bags are made of High-Density Double PVC Coated 1000D Polyester for added strength and worry free filling and draining.

The Straight Line Sumo Sacs are the most flexible, puncture-resistant ballast bags available today. Sumo Sacs are made with 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. Straight Line spent a lot of time measuring different boats to make sure that these square bags will fit anywhere on any boat.
