Watertight Flush Hatch with Storage Bag – Ø205 mm Opening, 280 mm Depth

This watertight hatch with bag addresses the challenge of limited storage on board by allowing you to keep important items dry even on a small boat or kayak. The set includes a flush-mount plastic deck plate (hatch) and an attachable inner bag. The hatch is made of durable ABS/polypropylene plastic (white color) that is UV-resistant and marine-grade – it won’t yellow or become brittle over time. Around its perimeter sits a rubber gasket (O-ring) that ensures a waterproof seal when the hatch is closed. The cover opens and closes with a twist (bayonet/threaded mechanism), providing quick access while also locking securely to prevent leaks.

The inner bag is constructed from waterproof fabric/PVC material and is sized to fit the hatch diameter, with a depth of about 28 cm. It offers a surprisingly generous storage volume for its size: you can stow keys, wallet, phone, maps, tools, or spare parts and keep them dry even if waves crash over the deck. The bag attaches to the hatch (via a retaining ring or clips) and can be easily removed if you need to pull out all the contents at once or to clean/dry the bag.

Applications & Recommendations:

• Ideal solution for small boats, kayaks, canoes, or RIBs where storage space is at a premium – this hatch with bag can be installed in a convenient spot (e.g., on a seat, in the cockpit, or deck) to serve as a dry compartment for valuables and supplies
• Suitable for sailboats and motorboats as an extra compartment – for example, use it to store a first-aid kit, boat documents, or electronics that must stay dry. Install in the cabin, bathroom, or other areas where you want a discreet built-in storage space
• Installation: Requires a Ø205 mm circular cutout. It’s recommended to cut the hole carefully using the proper tool (hole saw or jigsaw) and to seal the cut edge before fitting. Use all the provided screw holes and stainless fasteners to secure the hatch firmly. Apply a marine-grade sealant beneath the flange to ensure a 100% watertight result
• Maintenance: After use or periodically, the bag can be detached and rinsed with fresh water. Make sure the bag is completely dry before long-term storage of sensitive items like electronics. Regularly inspect the hatch’s O-ring seal – if it gets dirty, clean it, and if it shows signs of wear, replace it to maintain a reliable waterproof seal
