It's the northerners who call it that I think. Posh southerners as supposed to call it the "Tweaker". But I kinda like the sound of SNODGE somehow....

 We've got an ex Merlin 2 times champ at the club, been having chats with him recently about pole systems and anything symmetric. Very useful. The lack of good symmetric sailors (locally) makes it difficult to gather info, so I guess we're lucky.  2 more L2s arriving at the club this season so we will be getting our heads together to work out the which systems suits.

Nice links Merlin almost tempted to buy a Merlin just so I can say I've got a "Snodger" on my boat.

Most boats have twin poles, but whilst you have two 'snodgers' (the pole downhaul that also pulls the guy ring into the outboard end of the pole) they lead to the same tail, so theres only one rope to pull.

Only one guy and sheet, as per normal symmetric system.

With carbon poles it is expensive to have two, but very swift to launch, and they make less noise clanging on the boom.

That's right, the Merlin poles are constantly connected to the sheets, when the snodger is released and the pole comes along the boom the sheet is allowed to float free. They have a pole uphaul on each pole, which is connected to one rope to control inside the boat. They don't normally have pole out lines, they clip on to the mast manually.
Needs to sail more...

If the Merlin one is anything like that on an MRX (probably the same) then once it's set up it's very easy to use, you just shove the pole out and clip it on.

Some of the ones at the Tiger had twin pole systems though- rope multiplication! Think there's some 5o5s run those sort of systems too, aren't there? Far too many ropes for my liking. I could see the words "WHICH PURPLE ROPE?" preceding something wet, sore and possibly expensive.

slight detour- was introduced properly to the workings of the old-style B14 pole system (on Rondar-built boats in the UK) on Sunday. The outhaul system is, somehat oddly, mounted internally, with the whole in a built-in pipe from bow to mast-step.

The Ovington ones have it simpler- there's a trench down the middle of the bow with a removable maintanence cover, and the blocks etc are outside the pole, like you'd find on most assymetrics.

 On the L2 the elastic just takes up the slack, also with the hook system it keeps the uphaul/downhaul tight and out of the way when the spinny is not in use. The part under tension is rope...I've never had a problem with that part of the arrangement.
