The James Bay would be an outstanding craft on the Yukon, Big Sue, Yetna, Talkeetna, Tanana etc and handle better than the Hudson Bay in PWS, Seward, Homer etc. It has almost double the load capacity over the HB. It's obviously bigger and heavier than the HB. It's unlikely you could jump beaver lodges like some do with their HB's and carrying the JB over a gravel bar and car topping would be out. If you carried a rope come-a-along to winch over the occasional beaver lodge, hauled something like the Pro-Pioneer in a bag to access the extreme shallow sloughs or line up some of the skinny rocky streams, then how limited would you really be compared to the HB? Both freighters use a short shaft so what other disadvantages are there compared to the HB? (other than cost) If a fella wanted to use one boat for everything like Yukon moose, PWS black bear, Seward silvers and Homer butts then why not go with the JB and 40hp?
