I was amazed at the relative speed of the Lincoln Hidden Pond 14. It was for years raffled as a fundraiser for the Source to Sea Androscoggin River trek. First it was paddled the 177 miles of the river, then the raffle took place.
Both paddlers had room and it was not that slow. And there were some riffles in the river and some waves at the mouth.
So a 14 foot tandem is not necessarily out of the question if the bow paddler has enough room to kneel when conditions get scary (and it will happen). Pelicans don't allow that room and bow paddler ejection is always a real concern. I don't know about Indian River canoes.
I think there might be more issues than which is better..keel or tunnel.
