In my never ending quest to re-invent the wheel I'm wondering what the effects would be to a kayak...say a wide 20 foot expedition kayak...if it was truncated by 4 feet, with a stern treatment somewhat like a wineglass wherry. How would it track and paddle? Would it glide...or wallow like a water hog. If anyone has an opinion I would love to hear it. Another thought...rather than shorten a standard kayak...could a kayak that incorporates a wineglass stern be designed with expectations of good performance...and looks? Any comments appreciated.
