The 9 Best Plastic Marine Hatches (2023 reviews)

We are personally inclined towards five oceans plastic marine hatch, it is not so pricy, but it overachieves its purpose and outstanding in important aspects. It is designed with a rubber o-ring that creates a watertight seal for safety and allows it to be used for interior and exterior applications. The screw holes even lined up perfectly. There's a gasket in the ring to keep water out when it's screwed in all the way. The string is a tether to attach loosely to the boat so you won't lose the cover. It includes a safety lanyard to secure the lid cover.

There's an ab o-ring under the threaded cap. The threads are deep, so it has a good grip. It will stick to fiberglass and gelcote, put on the outer ring of a deck cap, and awesome stuff. It comes with a plastic tie that connects to a center point of the underside of the cover.

Why We Like This:

Marine and beyond stop leaks, water proof
Highly recommend for new or replacement applications

Best For Marine Hatch: Five oceans Marine Hatch

Buy on Amazon

Not everyone likes to purchase hatch for their regular usage, but the five oceans marine hatch would be an anomoly. The white marine access hatch is made for floor mounting due to low. It has a smooth-textured lid with reinforcement ribs for added strength. It comes with a cut out stencil which makes the install a lot easier. It offers a 120 degrees lid opening and the handles are locking slam latches. It's a good hatch and probably the best replacement for the older ones of the same dimension, which do break after a couple decades.

Why We Like This:

Perfect fit for a broken hatch cover on a 25 year old boat
Seals well and easy to open
Excellent, very sturdy and no leaks

Best For plastics: Yaemarine Plastic Marine Hatch

Buy on Amazon

Compared with other hatch in this category, the yaemarine plastic marine hatch has a convenient design. This hatch is designed so water has to puddle on the hull, go under the cover, up over a plastic ridge that is sealed to the cover with a gasket. It comes with a non-skid surface and it is designed for installation on an internal or external flat surface.

This size has two cam latches. The cover does not cover the frame or bolt holes, so water will puddle between the cover and frame, and relies on a gasket that the cover only rests on. It is suitable for plastics, be sure to clean it good with alcohol or white vinegar to remove grease.

Why We Like This:

Well constructed to withstand hard use
Good investment for long term

Best For storage unit: Pactrade Marine Plastic Marine Hatch

Buy on Amazon

The pactrade marine plastic marine hatch might be a relatively new release, but it's still nothing short of impressive this year, thanks to multiple price cuts and added new features over the past few months. It stands up to tough service, extreme weather and solvents. It is a high quality waterproof inspection deck plate made of uv stabilized plastic. The latch is flat on the lid, unlike the T shaped design of others that must be lifted and then twisted to open. The nuts and bolts are easy enough to acquire, except that it requires an extra trip to the hardware store.

This design has a lid that overlaps the opening and a good seal on the lid that keeps water out. There is also a foam gasket seal beneath the hatch to keep water from seeping in around the outer edges and through the mount screw holes. The top opens much easier than the original screw on lid and it is water tight. The inner bag is not water proof and is thin nylon.

Special design with the red storage bag, more safety and useful
Watertight access point without the use of any tools
Hatch cover that is actually watertight
