I've checked the measurements carefully, and the bow transom dimensions are the same length as the mating edges on the bottom and sides. There's just a funny gap at the bow, and everything is VERY tight already.
The instructions say to start at the stern and work forwards, which is what I did. I suppose I could unwire the bottom, and re-do it, working back from the bow. Any thoughts?
About the number of wire ties: I've doubled the number on the forward third of the hull, where everything bends inwards to the bow transom. They're spaced every 3 inches, instead of every 6 inches elsewhere.
