Mc,

Yes I got it thank you very much for getting it to me. I have not even had a chance to print them - I'll check it out tonight. I'll try and grab a picture of it. One of the guys on the site came up with the idea - it's simple/brilliant.

In the nutshell: take a pc of PVC that can slide inside the floor scupper. Cut the PVC so it is 2" or so shorter than the length of the scupper tube. Put some electrical tape around the outside of the top of PVC tube. Push the PVC tube down into the scupper drain so the top of the PVC tube is just above the scupper drain tube. The tape should make it fit snugly within the scupper tube.

So far - you have a tube that snugly fits inside a tube. Remove the PVC tube. Take a cheap paint glove - the flimsy, rubber throw-aways ones. Cut the longest finger off where it meets the hand of the glove. Now, cut the finger tip off. Now you have a rubber tube. Place one end of the glove finger over the end of the PVC tube, slide it on 3/4" ( think condom - sorry for the graphic there! ). Tape it in place with electrical tape. Now slide the PVC with the rubber finger into the scupper w/ the rubber finger part extended and into the scupper hole first. The PVC should fit snug in the scupper 'cause you put tape on it initially to give it that snug fit.

That's it. Water will flow out of this contraption. But, when sea water wants to come back in from weight or whatever, the rubber finger squishes closed allowing no water to come in. It works awesome. It probably should have been called the Sphincter, but Vortex sounds way cooler ! Anyway, one of the guys figured this out and it is very effective. The only drawbacks: it reduces the size of an already small scupper. It could get clogged and trap water in ( this has never happened to me ), but I do remove it after each trip. I keep 'em in the teak rod holders so I can put them in when I cast off.
