This set of two 260 lb ballast bags are great for adding weight in compact compartments such as the ski locker, under seats, or next to direct drive motor.

The Fly High Pro X Series Side Sacs fit along the side of the engine compartment on direct drive inboard boats but will also fit under the seats and in compact storage compartments in many boats making them ideal for stashing weight where it will be hidden.

One of the more versatile wakeboard ballast bag sizes from Fly High, the Side Sac Set can be used in multiple locations throughout the boat to add additional ballast where it's needed, and since they're sold as a pair, you get a great value.

The narrow profile of the side sacs also make for a more compact fit than a 400lb. V-Drive Surf Sac or the 750lb. Fat Sac making them a perfect anywhere space is tight.

Perfect ballast supplement

I have a 2002 Mastercraft X-Star with the stock hard tanks in the back (300lb/ea) and upgraded ski locker sack (400lb) on switches. We bought two sets of these sacks to keep full 100% of the time in the boat. We put two in the back and they stay full with hose water for the entire summer. We have two more that we use for the bow depending on how many people are on the boat. If no one we use two up there and if we have 4-5 folks we just use one, which fits perfectly in the walkway of the bow (when using two we stack them). THE WAKE IS PERFECT with this setup, stock ballast completely full and four people. As we add people to the boat we empty ballast and therefore don't have to worry about getting fat-sack water in the boat. This should work on any 205V X-Star, X1, X2.

Side note - I gave four stars on quality based on the fact that the connection ports for these types of sacks aren't perfect. When filling it doesn't take much to accidentally knock the hose off and get water squirting from both the sack and the fill device. Just have to be careful.

Great ballast!

I have placed one in each rear locker of our Nautique 216V. It really augments the factory ballast in wake boarding nicely and we can then pull one out to place in the bow for surfing. Excellent quality materials and the red looks great!

not quite enough for me...

While the quality of these bags are top notch, they just aren't big enough for surfing in my 22' V-drive. If you have a smaller boat, i'd buy them in a heartbeat, but I'd look for something bigger if you can fit it.
