Waterproof Under-Seat Storage Bag for Inflatable Boat Seats (85/95/105 cm) – Gear Organizer and Cushion

This bench seat bag is specially designed to enhance the functionality of your inflatable boat by utilizing the empty space beneath the bench. Instead of gear taking up floor space (where it can get wet) or cluttering the deck, everything can be neatly stowed under the seat in this easily accessible bag.

Materials & Construction: The bag is made from durable polyester fabric with a waterproof/water-repellent coating (similar to heavy-duty canvas or Oxford cloth). The seams are reinforced, and the attachment points are extra strengthened to support the weight of contents in rough conditions. The bag’s opening typically features a zipper or a flap with Velcro – allowing quick access to the contents while ensuring secure closure so items won’t fall out. The bottom of the bag is flat, creating a rectangular “hammock” shape under the seat when installed.

Installation: On each side of the top of the bag, there are adjustable straps with buckles or snap fasteners that loop around the bench. Simply slip the bag under the bench and tighten the straps above it. This system adapts to different bench thicknesses (wooden, plastic, or aluminum seats). The bag can be easily removed when not needed or carried separately like a duffel if you need to transport the contents.

Sizes and Boat Fit:

• 85 cm length: The smallest model, suitable for benches ~85 cm long, as found on inflatables up to about 3.0–3.3 m in length. (Example: a small dinghy or compact inflatable with one bench.) This bag is perfect for those smaller craft where space is at a premium and every bit of storage helps.
• 95 cm length: Medium model for benches around 95 cm – the most common standard on boats ~3.6–3.8 m long. (Example: a typical 3.8 m RIB with two bench seats.) This size provides more volume for gear, ideal for family outings or fishing trips where you have more equipment.
• 105 cm length: The largest model, matching bench widths of ~105 cm, typical of bigger inflatables over 4.0 m. (Example: a 4.2–4.5 m boat carrying 6–8 people.) Here, the capacity is maximal – the bag can hold a substantial amount of gear, perfect for extended excursions or camping with the boat.

Regardless of size, the depth of the bag (~20 cm) is designed to accommodate plenty of items without hanging so low that it hits the floor of the boat under normal load. You can fit rolled lifejackets, a foldable anchor, ropes, water bottles, food, fishing tackle, a first aid kit, etc. – all those things you’d otherwise struggle to find a place for.

Practical Benefits:

• Organization: Keeping items in an under-seat bag means the deck stays free of obstacles. This is especially important when moving around the boat or casting a fishing line – nothing is rolling around underfoot.
• Gear Protection: The bag offers protection from direct splashes and incidental water on the floor. Items inside remain much drier and cleaner than if left loose on the bottom. (It’s not a fully dry bag, but it provides a good barrier.)
• Improved Stability: Storing weight (e.g., spare fuel canisters, tools) centrally under the seat helps maintain a better center of gravity and balance for the boat, as opposed to having everything in the bow or stern. This can contribute to smoother planing and handling.
• Portability: When you reach shore, instead of carrying multiple loose bags, you can simply unclip the entire under-seat bag and take it with you as one piece of luggage. This makes unloading much easier.
• Tidiness: You can designate the bag for specific gear – for example, keep emergency kit and tools in one, and food and clothing in another (if you have two benches and thus two bags). That way everything has its place.

Recommendations: When choosing a size, match it to the length of your bench – the bag should be equal or slightly shorter than the bench to hang neatly without excess material. It’s advisable to periodically rinse the bag with fresh water (especially the zippers/Velcro) to wash off salt and extend its life. If the boat will be stored for a long time, let the bag dry and store it in a dry place to prevent mildew (especially if it was put away wet).

This bag is an excellent accessory for any inflatable boat owner looking to keep their vessel organized and maximize every bit of space.
