Flush Mount Aluminum Hatch

Our custom flush mount hatches are delivered completely assembled and ready to drop in any existing cutout in your boat deck. The weathertight hatch assemblies are suitable for installing on boat decks as well as vertical surfaces for door access. Specify your deck cutout dimensions and other options below to order your hatch.

Our CNC formed hatch channel is designed to integrate the mounting flange, drainage channel, and seal ledge with a single component. This means that the hatch frame only needs to be welded at the corners and there will be minimal distortion and bowing in the frame.

Standard features:

  • Full length aluminum piano hinge with stainless fasteners.
  • Drain hole in gutter channel with welded 5/8″ hose barb.
  • Rubber hatch seal on lead underside.

Options:

  • Finish: bare aluminum, diamond plate, or powdercoating. Powdercoating will add 1-2 weeks to leadtime.
  • Upgraded thickness for commercial applications.
  • Gemlux stainless steel or Perko latches.
  • Locking or non-locking. Orders of multiple locking latches will be keyed alike.
  • Gas springs or coiled spring lid supports.
  • Pre-machined hole patterns for deck flange.
  • Welded stiffeners on underside of lid.

Feel free to contact us if you have any questions or need additional customization.

Dimensions

  • The hatch ordering dimensions are based on the cutout opening you will fit the hatch in.
  • The hatch flange will overlap the cutout by 1.5″ on all 4 sides. The overall hatch dimensions will therefore be +3″ greater than the cutout size.
  • The gutter channel is 2″ wide all around. The clear opening inside the drain gutter channel is -4″ less than the cutout opening.
  • If you are ordering for a trapezoidal cutout, use the greater of the 2 edge measurements.

Frequently Asked Questions

How many latches do I need? 

  • We recommend 2 latches when the hatch length exceeds 36″. With a long hatch and a single latch, the corners may not compress the seal adequately.

Do I need the stiffener system? 

  • Small standard hatches (both dimensions under 24″) don’t need a stiffener unless they are frequently stood on.
  • We recommend adding the stiffener option if any hatch dimension exceeds 24″, or if there will be frequent loads standing on the hatch.
  • The stiffener system is a requirement if you’re selecting the Commercial HD version.

What is the Commercial HD version? 

  • The lid and frame thickness is increased to 0.188″
  • The stiffener grid is designed to support heavier loads.
  • Recommended for commercial applications or large deck access hatches (>36in on both sides)

Are the hatches watertight? 

  • The correct definition is WEATHER-TIGHT. Our hatches are sealed where the contact the flange lip and they will drain water that enters the channel through a 5/8 drain barb, which can be plumbed overboard or into the bilge. The hatch will keep your compartment dry so long as you allow the channel to drain properly.
  • The term watertight means you can submerge the hatch under a head of water and it will not leak. Truly watertight hatches require a least 4 compression dogs and precision machining of thick billets

How do you install the hatches?

  • The hatches should be installed by screwing, bolting, or riveting it to the deck surface with a quality adhesive sealant. We can pre-machine this hole pattern for you.
  • You can also weld the hatch directly to your aluminum deck, although you must be cautious of excessive warping of the deck and hatch when welding such a large perimeter. We generally recommend mechanically fastening even for aluminum boats.
