I just got back from a nice 4 hour paddle in my WD12. I took it the entire navigable length of the Middle River right out into the Chesapeake Bay and back. For those of you with safety concerns, the highlight of this trip was when a severely inconsiderate cigarette boat crossed in front of me at full speed (ignoring the posted speed limit on the buoy). The wake broke across my bow submerging the boat all the way back into the cockpit. The front half of the WD12 only stayed under for a fraction of a second before vigorously popping up out of the water and settling down again with a splash. There was never any feeling of loss of control or stability. The boat took the wake and grinned.
Which was better than I did. I took the opportunity to demonstrate that I know the rude words for certain bodily functions in 5 languages, but the butt-boat driver was too far away to appreciate them.
Definitely needed the sprayskirt, though. Without it I would have been swamped.
So go forth and build your Ducks, serene in the knowledge that they can handle the big world.
