Erez,
here is another cheap and easy to build snuffer. It's the one we still use on our Tornado.
http://www.tornado-norge.org/stockholm2005/_DSC3495.JPGJust bend a pice of alu tube into the shape you want (make a template/mould to bend it round if you want it to look really nice) or fill half of it with sand and heat the area you bend. Sand the ends with 80grit, then wet-sand the ends with epoxy and wrap some glass around them to hold them together. When the epoxy has cured, build a bracket to mount it to your pole.
The sand fills the area you are bending and stops "kinking" of the tube, while the wet-sanding with epoxy stops the alu from reacting with oxygen in the air so you get a proper bond.
It works almost equally well from both sides (it's slightly better on starboard tack, but I think it would be better with some more sanding and a slightly different mounting angle).
The alu dont notice the friction from the retrieval line, and it's pretty smooth without sanding.
