Yes. They can be found on the aft of rigid-hulled inflatable boats (RIBs).<br /><br />Normally, if it is above the waterline, it is a scupper. If it is below the waterline it is a drain hole and has a removable plug. There is a critter that is a combination of the two the drain hole is below the waterline until the boat is on plane, then it is above the waterline and you pull the plug then it acts like a scupper. It's usually a good idea to put the plug back before coming off plane.
Drifting live Bait, the drains on the transom are in & out pending on conditions, flat calm there about 2" above the water line, what scupper would work better, flap type or ball ?
I very much dislike the ball type but then I don't care all that much for the flappers either.<br /><br />The thing I don't like about the flappers is that if you tow for long distances and at relatively high speeds (interstate towing mostly) what you tend to find is that the flaps themselves tend to be gone when you get where you're going. With the ball type its just something else back there to snag lines on or have some yard monkey break off with a fork lift (I say that as a fellow who spent a good bit of his youth working in Maimi boatyards as a yard monkey).<br /><br />At any rate now days I use the flapper types but I remove the flappers themselves.<br /><br />By the way Sloopy, this is what you have to look forward to if you go fish with us in May:<br /><br />
