Old Town's larger war canoe was actually 34', Kennebec offered one at 35' and Carleton's was apparently the largest at 38'. They were constructed the same as your standard wood and canvas canoe, the main exceptions, apart from size, were the presence (usually) of a keelson, and beefier rails and stems. In the early days of the war canoe craze, many builders built all-wood versions ranging from 30-35 feet.
Unwieldy critters, as anyone who has crewed in the Carl's Paddlin' store's 34' canoe in the Madison, WI Paddle and Portage race will attest too... We also confirmed they are not all that useful for solo freestyle paddling either.
They can be awkward to cartop too, see attached
