No i jest, my arms arnt short and i wont be giving up my boating but i have decided to do something about the short tiller and the uncomfortable position on my left arm.
Firstly i raided my off-cut wood bin and found a lovely piece of Hard Pear and began truing this between centres.

Then it was given a shape of both function and hopefully something pleasing on the eye.

I sanded this up to 400grit and gave it a soft sheen finish with a very hard wearing friction polish. Here it is.

This is a simple push fit into the original tiller arm and gives me the chance to face forward as i punt along up the river whilst still remaining in control of the dinghy.
