depending on the emergent growth that you're trying to pole in....
The big Clappers of the coastal spartina marshes can be easily poled for out of a a traditional jon boat...the higer the flood tide the easier it becomes but the spartina where the rails hide isn't all that difficult to pole through with a flat bottomed, blunt nosed boat....
The little Rails on, either tidal marshes like the traditional poling grounds in NJ and on the freshwater marshes are another thing entirely and boat design makes a big diffeence in success....
I'v enot had the priveledge of hunting the emergent rice beds in NJ and Maine for Sora's but the boat design, (see Hagerbaumers drawing posted by Scott), dates back to the late 1800's when Rail Gunning was THE KING of shooting sporst, and it has changed little since so I sure wouldn't argue that design in those conditions....I've seen those rice flats and as Scott said the narrow pointed is essential to being able to drive the boat through the heavy vegetation. Which, of course, is why Wasson's Merrymeeting float worked so well for him....
In the freshwater marshes of Missouri where the emergent vegetation is promary a think tangle of smartweed we, (Mark Schupp, Ira McCauley, Worth Matthewson, myself and others), used the Mo Marsh FatBoy to good effect the boat having enough of a pointed bow to be able to shove it through all but the heaviest of smartweed clumps.....The MoMarsh DP did an even better job due to the rocker in the boat and the platform on the rear....once you'r comfortable with poling, and WHO CARES if you fall off the water warm in Sept. and its never really all that deep, the rocker allowed the poler to move so that the bow could be lifted so that it would ride over instead of through the vegetation making it much easier to pole.....
The real performer though was the Devlin Pole Boat that Mark Schupp built....sharply pointed at both ends this boat outperformed the other boats we used slipping easily through the all but the thickest of smart weed clumps......neat boat for sure but pretty specialized and I'm not sure that most people would have the opportunities to make building on an smart choice, (like THAT is ever a factor in the search for "a boat for all reasons").
To your specific question on the Pod I'm sure you could make it work but its lack of rocker, the blunt bow and the cockpit size is going to make it a poor performer, IMO, in all but the thinnest of vegetation which isn't where the Rails will be......
Can't find any pictures of the FatBoys and DP's in action, (maybe Mark will have a couple). This is the Devlin Pole Boat, Mark Schupp poling Worth back to the ramp after a successful morning.....
Mark pushing me through the Smartweed...
Mark again at the pole with the SPORT taking a shot at a "strong flying" Sora...notice that the boat is now WHITE which is a traditional Rail boat color.....
Goo dluck on your Rail Adventure...they may be small and they may not fly like Doves or Teal but they are great fun to hunt....
