The square stern Ducker DO was only made in 1958. Serial numbers were from 100 to 305, a total production of 205.

The DO has several disadvantages compared to the double-ended Ducker: (1) hull drag from the square stern makes it significantly harder to row or pole (square stern canoes have the same problem); (2) square sterns don't turn as easily, or back up in rice or reed beds; (3) they're harder to blind up, and (4) lacking the structural strength of the normal Ducker, the DO's stern is more susceptible to damage. A simple motor mount can easily be fabricated for the pointed stern of the normal Ducker, which obviates the DO's only advantage.

The DO was dropped after just one year; duck hunters just didn't find it worthwhile. AlumaCraft later experimented with an Economy Ducker that lacked the usual refinements of decking, cockpit, stabilizer tubes, blind pole loops, etc., but it never really sold and only 452 were built.

I suspect your chances of finding a DO today are slim to none - original Duckers are hard enough to find, and there were more than 13 of them built for every DO square stern.

Incidentally, the original Ducker came with heliarc-welded aluminum oars, which are now even more rare than the boats themselves.
