i mean the shape of the central edge of the bow, what you see, if you look exact from the side (perspective of your drawings here), looks very similar.
both are bended inwards above the water-line.
The X-bow have nothing with a canoe to do. The only reason for the shape is due to the X-bow is basically a supersized bulbous bow. And as I said the inspiration those engineer had was not a canoe, but a bulbous bow.
that is sharing the same shape, doesn't mean it is the inspiration for it, it's like asking was that car an inspiration, to that car from a different company.... just because they are similar.
