Inspection Hatches: Easy and Secure Access to Your Boat's Compartments

Inspection hatches, also known as access panels or inspection covers, are a fundamental component for any boat, whether sailing or motor. They provide quick and easy access to compartments that would otherwise be difficult to reach, such as tanks, plumbing, electrical wiring, and bilges. A well-chosen and installed hatch facilitates maintenance, inspection, and repair operations, helping to keep your boat in perfect working order.

We stock a selection of inspection hatches and covers, mainly made of polypropylene to ensure resistance to weathering and marine corrosion. Diameters vary to suit different needs, with external dimensions from 132 to 260 mm and access diameters from 91 to 240 mm. You're sure to find the right model for your boat.

We offer products from top brands such as Osculati and Whale, known for their quality and reliability. Our hatches guarantee an optimal watertight seal, protecting internal compartments from water ingress and splashes.

Nautica Basile's Advice

• Replace old hatches: If your hatches are worn or damaged, replace them immediately to prevent leaks and structural problems.


• Check the seal: Periodically check the seal of the gaskets and replace them if necessary.


• Choose the right material: Polypropylene is an excellent choice for its corrosion resistance, but also consider AISI 316 for particularly exposed applications.


• Clean regularly: Remove salt and dirt from the hatches to keep them in perfect condition.

Complete your equipment with our watertight cable glands to protect electrical wiring that passes through bulkheads. And don't forget to check the condition of your bilge pumps, which are essential for keeping your boat dry and safe.

Installation requires precise drilling of the surface and fixing with screws or bolts. Be sure to properly seal the edges with marine silicone to ensure a watertight seal.

Can I use an inspection hatch to access the drinking water tank?

Yes, but make sure the hatch is made of materials suitable for contact with drinking water and that it is easy to clean and disinfect.

What are the most common sizes of inspection hatches?

Sizes vary depending on the application, but the most common diameters range from 100 mm to 250 mm. Carefully measure the available space before choosing the right hatch.
