The Best Boat Hatch Covers for Storage, Light and Ventilation

Are your boat hatch covers faded, peeling or leaking? Are they constantly falling open?

Have you constructed an elaborate bungee cord system to keep it closed?

Whether you have a sailboat, a liveaboard trawler or even a fishing kayak, boat hatches offer convenience and comfort factors for everybody on board. If your boat hatch covers have seen better days, it might be time to do some replacing.

Fortunately, replacing boat hatch covers is not a terribly expensive procedure, compared to the many other things that can happen when you own a boat.

Read on for some hints and tips on choosing the best boat hatch cover for your boat.

What Is a Boat Hatch Cover?

A hatch is a place on a boat for storage, light or ventilation. Most people think of the window at the front of the boat, right above the V-berth, as a hatch. I like to call it the star-gazing window (but it's technically a hatch). 

Built-in storage containers like live wells are also called hatches. Electric/fuel line access openings are also known as hatches. The cover is, quite simply, the lid that you open and close.

A whole hatch system consists of trim, O-rings, support poles (like cam latches) and an optional screen (for window use).

Uses for Boat Hatch Covers

  • Access for storage
  • Live well coverage
  • Protect electric and fuel lines from water and weather
  • Windows/Ventilation (you can even install roller or pleated shades to block light)

Features of Boat Hatch Covers

Corrosion Resistant

You'll want to be sure to choose corrosion-resistant or non-corrosive materials that can withstand saltwater and marine conditions.

Vertical or Horizontal Use

Depending on where the hatch is, it can be positioned either vertically or horizontally. Boat hatch covers come in either style.


Well-sealed trim prevents leaking, either from outside elements getting in, or inside contents spilling out (such as with live wells). Do you really want a bunch of bait water leaking out all over your boat deck? No, the answer is no, you do not.


Boat hatch covers come in a variety of shapes: square, round or rectangular. A long rectangular one is good if you're planning to store water skis, fishing rods and floating water mats. Small square ones are perfect for storing electronics. Larger square ones are good for anchors and anchor rope.

Material and Construction

Boat hatch covers are typically made out of aluminum or polycarbonate. Aluminum is a bit heavier than polycarbonate, but both are durable, corrosion-resistant and hold up well in marine conditions.


If the hatch is on the floor or interior sides of the boat, where people will be walking, you'll want to make sure it doesn't stick out too much.

Additionally, window hatches on the deck (like for a V-berth) shouldn't be so tall that people trip over them.

Types of Window/Portlight Boat Hatch Covers

For windows, there are several types of boat hatches.
  • Flush:  The flush-style boat hatch cover sits flush against the surface of the boat, whether it's on the deck or the sides.
  • Low-Profile:  A low-profile design is lightly more elevated but still close-fitting.
  • Medium Profile:  The medium profile has more of an edge and a taller pronounced look.
  • High Profile:  A high-profile hatch is definitely noticeable. It's a good choice for a side window. It wouldn't be a good idea for floor installation.
  • Pilot Hatch:  The pilot hatch type is usually found in cockpits. It slides back and forth rather than staying open with a cam arm.
