About Deck Fills & Drains

Cockpit Drains & Scuppers

Defender Marine offers a variety of cockpit drains, self-bailing scupper drains, and thru hulls with scupper valves. Thru hull valves and deck scuppers can be installed above or below the waterline and are offered in a polymer composite called Marelon, injection-molded nylon, or molded fiberglass.

Self bailers take the guess work out of cockpit drains.

When a boat is underway the pressure of water running out through the scupper opens a one-directional valve to release the water from the hull. When the scupper is closed, during rest, no water can leak into the boat. Self-bailers assist bilge pumps in keeping the hull free of excess water and are especially helpful on boats that are "wet" or take on water and spray while running.

What are deck drains made of?

Defender Marine offers scupper drains fabricated out of a variety of materials. Marelon is a polymer composite that never cracks or loses its shape, while injection-molded nylon is strong and UV resistant. Molded fiberglass cockpit drains, as well as polycarbonate boat scuppers, offer a few more options while shopping for scupper drains.

I've got a new scupper, now what?

Installation above the waterline is not complicated and can be a DIY project - just remember to measure twice! Also, examine that boat scupper drain that you have purchased and be certain that it will work for your application. Hose barb or threaded connections are questions that need to be answered before the project starts, as cockpit drains and scuppers must be plumbed to exit the hull. Be certain the project is completely prepped, and all gasket materials are ready to go before you start!
