The 450lb. Straight Line Sumo Jr. V Sac is perfect for placement in any v-drive locker or for placement in the bow or walk way. This is the closest ballast sac in size and dimensions to the Fly High V-Drive Surf Sac.
At 450 pounds of capacity, the Straight Line Sumo Jr. V Sac is a great option for adding a significant amount of weight without taking up a lot of height.
Since 2011 Straight Line Sumo Sacs have been outfitted with 1" NPT threaded ports allowing for the easiest integration into your factory ballast system. For the easiest integration possible, shop our factory ballast upgrades.
The SL Sumo Jr V. Sac is a perfect fit under side seat in most v-drive boats, making it a great option for further enhancing the surf wake.
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.

Perfect for Ski Locker in Sea Ray 185 Sport
Fits nicely in ski locker of the Sea Ray 185 sport. The Link fill fitting is awesome as there is very little water spilled when filling and emptying bag
Perfect for under the seat - 2005 Crownline 260 EX
Perfect height for under the my side rear seat. Adds weight but does not get in the way. Fittings are easy and quick for attaching the sumo pump.
Good bow bag for closed bow.
We have a 1993 Sanger DxII that we use for wake surfing. This bag fits nicely between the first and second bulkheads. It also lengthend our wake quite a bit, allowing for a decently sized pocket.
Perfect Under Seat Wakesurf Sac
We have a Malibu VLX with the factory ballast and a Sumo 750 in the rear locker. I always put this sac under the seats on the regular side to help produce a longer wave with a ton of height. Fits great and I love the built in check valve fitting.
