I used to row a 16fter. While it can be a surprise what they can squeeze down with a good oarsmen, the issue that had me move onto a smaller, more narrow boat was the width in places where, no matter the skill, it just didn’t fit.
Like most, the ol 14fter was the solution. A narrow 6’6” x 14’ Avon Ranger and then moved to the oddball looking and sized but fits my needs exactly.... Hyside Pro 14.8’ x 6’4”.
Basically, my need to fit through narrow spaces on technical, multi day rivers outweighed the shallower draft of a light 16fter.
Yer needs and mileage may vary and no one raft is perfect for all situations.
