I’m having bother lofting a shape. The end result is to be a canoe hull. The curves in my file are based on the cross sections of a canoe. From these cross sections I am trying to loft the canoe hull shape but something odd happens between the last and second last curves at the end of the canoe. I have a feeling it is because the last curve is perpendicular to the previous one - if this is the problem - how would I deal with it?

Thanks in advance of any advice
