Straight Line Sumo Sac Ballast Bag 325 for all round use in the boat. Easy to use, creating larger wakes so you can have as much fun as possible.

Liquid Force SUMO Ballast System is the fastest filling ballast system in the industry! 

Equipping your boat with SUMO Ballast means less time filling and more time riding your massive wake! All of the SUMO ballast System is easy to use, durable and convenient. Sumo ballast is designed to work as a plug 'n play option with your factory ballast system or on deck with our high speed SUMO pumps. Available are an extensive selection of ballast bags to fit any boat or budget.

The Straight Line Sumo Bag is designed to sit anywhere in your boat and will add 325lbs of additional weight to the front centre or rear of your boat for a longer, cleaner wake.

Every SUMO sac is double welded to ensure a watertight seal. You can see the smooth and clean seams on the outside of every bag, and a second welding operation applies an inch wide sealing tape to the inside of every seam.

These are the most flexible, puncture-resistant ballast bags to date. Sumo Sacs are made with a sandwiched, woven polyester core for maximum strength while still remaining flexible enough for storage. Each bag is reinforced both internally and externally with glued and taped seams, creating a nearly indestructible bag.

Everything you need to know about our Shipping & Delivery Services

Your business is extremely important to us and if you're not happy then we're not happy. We are therefore fanatical about making sure that everything arrives with you in perfect condition and in good time.

Here is a summary of how we do things.

1) We aim to process and ship all orders on a daily basis if placed before 3pm Monday to Friday, Sadly we are not able to ship orders at weekends or Bank Holidays (we like to get out on the water sometimes too). If you place your order after 3pm then we will still endeavour to process and ship it on the same day but this may not always be possible until the following working day.

2) For goods stored in one of our satellite warehouses, transhipment may sometimes cause a slight delay. This is rare though and we'll always notify you straight away if this will potentially affect all or part of your order.

3) For goods on re-order from our suppliers but not physically back in stock yet the words "Coming Soon" or similar will be displayed. These goods are available for pre-order only over the phone by calling +44 (0)1597 850114. If you pre-order something we will let you know the arrival date that we have been quoted by our suppliers, but we're afraid that these dates do sometimes change but we'll always try and keep you fully in the loop. By pre-ordering goods you are basically securing them for when they arrive with us. Pre-orders are processed and shipped on a "first come first served" basis i.e. processed in strict chronological order (the first to pre-order will be the first to receive their goods).

4) For very urgent orders please contact us on +44 (0)1597 850114 and we can potentially upgrade your delivery option to suit your requirements.
