Best For Marine Hatch: Five oceans Marine Hatch

Buy on Amazon

These are nice little hatches. The white marine access hatch is made for floor mounting due to low temperatures. The handles that lock the hatch break off fast. The size of the opening is actually larger than the required size for this hatch, but the outside dimension of the hatch is large enough to cover the excess. It is great for use in a high-traffic area.

The twist lock handles on the new style are far better than the older style(1999)ball & snap locks which often are difficult to open. There is a lip inside that will fit into the hole. It is ideal for additional storage (bait, daily catch, fuel line access, or any other compact equipment), ventilation, or marine inspection.

• Excellent, very sturdy and no leaks
• Inches wide and 3/4” x 3 1/2” notch for the latch hinges
• Seals well and easy to open
• Perfect fit for a broken hatch cover on a 25 year old boat
