Very sorry to hear about your boat. I once had a 24' boat that was taken off its mooring by another boat that broke loose, totaled my boat. I know how you feel.
I have an unfinished tiller I made out of maple I keep as a spare. You are welcome to borrow it. I also have 3/4" thick ash boards if you wanted to laminate them and make your own.
I'm located in north jersey, let me know if I can be of any help.
