Straightline Sumo ballast bags add movable weight where the boat needs it, with heavy-duty construction and high-flow fittings designed for repeated filling and draining. Choose the shape and capacity that fits the space — the point is useful, controllable ballast without turning the boat into a permanent plumbing project.

Features:

• 675lb capacity — adds serious bow weight to help shape a longer, cleaner wave.
• Works in open or closed bow boats — flexible placement across a wide range of boat layouts.
• 100% compatible with Sumo adaptors and pumps — integrates straight into an existing Sumo system.
• Proven Sumo construction and convenience — straightforward ballast without reinventing your setup.
