Fellow-Ship,

Thanks for chiming in. I've read your post several times and still can't visualize how the vortex works.

My first question is, can it be applied to a scupper system that drains out the sides of the boat. Secondly, does it allow for water to leave the deck or is it meant only to stop the flow of water (in or out).

Thanks for your help.
