This is a sailing canoe made with the free tool FREE!ship that you can download here. The designer gives you offsets you can enter into the software. This way you can make it completely to your needs.
The length of this canoe is 16 ft with a 2.5 ft beam.
The designer offers help with the plans but it’s an older (2008) website so I’m not sure if the contact info is still up to date. You could try to find him on the Canadian Canoe routes forum where he used to be a frequent visitor.
