That is a great explanation and it makes perfect sense, but I am thinking that measuring from the hinge of the boom to the loop for the mainsheet and then calculating the dimensions would be easier. The old track was flexible so went straight as soon as I pulled it off the deck.
It looks like I am going to have to task a machine shop with the jib track, and I am not relishing that task since getting anything done these days seems nigh on impossible, and shipping a 17'4" track to the boat will be quite a challenge, although luckily I still have the port track to copy..
