Correct. It’s just a clamshell facing aft to prevent scooping water while underway. It also acts as a sort of Venturi as well which helps to “pull” water out.Holokai, that's really an entirely different setup given there is no hose. I assume what you have there is similar to lobster-style boats I'm familiar with in Maine. It's basically just a hole in the side of the boat. The water "deflector" is different too - it's really just a deflector, right? Meaning, there's no "grate" to trap foreign material (leaves, etc)?
I’ve been contemplating how to redo the scuppers and delete the hoses though I’m not sure that would work with the way the hull is constructed (too much stress on a rigid tunnel/drain vs the hoses due to the deck and transom being separate pieces).
