While you can do it no problem, even single I have found I did not like the sheet connecting to the tramp as it was but another obstacle keeping me from getting to the other side. (I have enough hinderances just with lines wrapping around my extremities and tillers hooking through my jacket or croakies)
I have not run it on the 16, but on the A class we rigged up a lot of center sheet systems running off the boom. It is done basically the same but uses the Ronstan pivot lead block with a cleat.. RF62175. It uses the same sail connections and can easily be run as an 8 or 9:1. I would use a bigger boom diameter due to the loads, but otherwise there are no hardware/boat mods to be made.
On the A the center sheet really made it nice down wind. I was going back and forth between boats and I am much more used to the rear mounted system, and being comfortable is more important to going fast.
It does not matter your poll not working as you left a lot of choices off the list anyway. For my vote I would have to say Falcon obvoiusly...
