When you are sorting through deck hardware seating covers, the first decision is usually whether you need to open the deck or fill it. Two new marine hardware pieces illustrate that fork clearly: the Seachoice 39161 Rabud Model 10x20 hatch and the Boat Marine Waste Deck Fill with a keyless 316 stainless steel cap. Both are deck and cabin hardware, but one is a large access hatch; the other is a compact waste fill. Choosing between them is really about the opening you need.
Quick verdict
If your project needs a wide opening into a deck compartment, the Seachoice hatch is the functional choice. If your project is capping a waste deck fill, the stainless keyless cap is the straightforward, lower-cost pick. They are not interchangeable: a fill cap cannot give you access, and an access hatch cannot cap a waste fill.

Product notes
#### Seachoice 39161 Rabud Model 10x20 Deck Hatch
This hatch is the larger and more involved piece of deck hardware. It fits a cutout of 11-1/4 by 21-3/8 inches, and the interior opening measures 9-5/8 by 19-5/8 inches, so it works well for reaching into a compartment or storage area. The built-in cam-action handle opens the hatch with one motion, while the 100-degree stainless steel hinges hold the lid up. The body is polypropylene and described as acetone proof, which is useful if you work with solvents near the hatch. Mounting requires #8 fasteners, and they are not included, so factor that into your installation plans. This is the higher-priced option, and it is meant for access rather than waste service. It is also made in the U.S.A. If you need to open a large section of deck, this hatch gives you the opening to do it.
#### Boat Marine Waste Deck Fill 2in 1.5in 316 Stainless Steel Keyless Cap
For a waste deck fill, this keyless cap is the streamlined choice. It uses 316 stainless steel, a material well suited to marine environments, and the keyless cap means you never have to hunt for a key before filling. This cap suits both 2-inch and 1.5-inch waste deck fill configurations, so it can match an existing fill riser. Because it is a cap, it does not open, hinge, or provide access into the deck; its job is to seal the fill point. It also costs noticeably less than the hatch, making it the budget-conscious choice if your project is a waste deck fill. For a straightforward replacement or an upgrade from a worn cap, this stainless option is the one to reach for.
Final choice by use case
Choose the Seachoice 39161 if you are creating a large access hatch for a deck compartment and can supply #8 mounting fasteners. Choose the keyless stainless deck fill if your task is capping a waste fill and you want a corrosion-resistant, lower-cost part. If you have a waste fill opening, the access hatch is the wrong tool; if you need to reach into a storage area, the cap will not help.
