Planning a boat deck upgrade often comes down to a fork in the road: replace a worn functional part or add something comfortable to sit on. Under the deck hardware seating covers umbrella, these two products sit at opposite ends. The Boat Marine Waste Deck Fill 2in 1.5in 316 Stainless Steel Keyless Cap Hardware lists at USD 45.49, while the boat Marine aluminum folding deck chairs seats are listed at USD 399.00.
Quick verdict
If you're solving a functional hardware problem, the deck fill cap is the lower-priced pick and comes in new condition. If you need a place to sit, the folding deck chairs are the only option here, but they come with condition caveats.

Closer look at each product
Boat Marine Waste Deck Fill 2in 1.5in 316 Stainless Steel Keyless Cap Hardware

This deck fill cap is a dedicated hardware solution. It uses 316 stainless steel, a material well suited to wet environments, and the keyless cap design means you don't need a separate key to open or close it. The 2-in-1 design adds flexibility if you're replacing an old cap. The keyless hardware is a notable convenience because you won't need to track a separate key when you're at the dock. This matters if you've ever mislaid the key for an older deck fill. Still, the purchase only covers the cap itself, so it won't solve a seating shortage or add comfort to the deck. For a focused hardware refresh, that might be enough.
boat Marine aluminum folding deck chairs seats

These chairs take the opposite approach by putting seating at the center. They're aluminum folding chairs, so they offer portability and a place to sit without taking up permanent deck space. They're in good used condition and were removed from a fresh water only boat, which is meaningful context for anyone considering them. The main limitation is the used condition itself and the fact that mounting hardware is only included if it appears in the pictures. That means you'll want to review the pictures carefully before committing to this larger purchase. If you already have a fresh water only boat and want foldable seating for sunny days, these chairs deliver that function directly. Just be clear-eyed about the used condition before you buy.
Final choice by use case
Choose the waste deck fill cap if your priority is replacing a worn deck fill with corrosion-resistant hardware. If you need to fix a specific functional failure and want a component that won't corrode quickly, this cap is the focused buy. Choose the aluminum folding deck chairs if your priority is adding foldable seating to a fresh water only boat and the condition trade-off is acceptable. When comfort is the goal, the chairs are the more useful addition; when hardware function is the goal, the cap is the more direct solution.
