The Straight Line Sumo 325 is perfect for placement in the center ski locker, rear trunk of direct drive boats or for placement inside the bow walkway. With it's long yet narrow shape this sac is a perfect extension of weight under the side seats on the port side of most V Drive boats. It is one of the most versatile ballast bags Straight Line offers.

This Sumo under seat sac is 65" long, 17" wide and only 8" tall. There are three 1" NPT threaded ports allowing for simple integration into your factory ballast system. The Straight Line Link valve is located on the top for convenient filling and draining using the Sumo or Super Sumo portable pumps.

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.

    Great fit in MasterCraft ski locker

    I have a 500 lb. Straight Line Sumo Hidden Under Bow Bag under the bow seats of my 1998 MasterCraft Maristar 210 and was looking to add a bit more bow weight to balance my rear weight of 1,500 lbs. The Sumo Sac 325 fit the bill nicely. My ski locker is 12 inches wide, just over 12 inches high, and 78 inches long, but the Sumo Sac conformed to the inside of the locker and fills to full capacity. My locker is more narrow than the Sumo 325, but the squeeze of the sides of the Sumo Sac just caused the sac to rise higher as it filled. Instead of the stated height of 8 inches, the sac rises to 12 inches. That is perfect for me because it stops just short of lifting my ski locker lid.

    I fill and drain my 500 lb. sac under my bow seats with an integrated Johnson Ultra Ballast pump and just put a Tee into the fill/drain hose going to the main sac. Although the fill/drain hose going to my main sac is 1 inch, the line going from the Tee to the Sumo Sac 325 is just 3/4 inch. That is fully adequate. The 3/4 inch hose was a lot easier to run down to my ski locker. I also added a quarter-turn PVC valve to turn off the Sumo Sac 325 if I want to keep it either empty or full when I fill or drain the main under-seat sac.

    When this sac is empty, I pile water skis on top of it. Even though the skis have metal fins, the sac stands up to the abuse. There aren't a lot of places where you need a long, skinny sac like this one. But if you have such a need, this bag is great.

    SUMO is right, beefy and sturdy

    Throw this fat guy in the hull and watch the wake curl up like you have a 400lb man that just got out of a buffet sitting on your swim deck with a butter knife carving the wake just right.

    A must have!

    The bag is great! Perfect for front / walk through . Sometimes I don't even need the bow sac when the 325 is up front. It's also great for tuning the wave if you put it in the back half if boat.
