I'd guess the boat originally had a swivel block and cleat behind the traveller. Modern 420's seem to favour strops, maybe you could convert to that and use the traveller fixings on the CB case for the block and cleat?

Correct. In fact I believe my centre mainsheet traveller is also illegal; the rules specify a rope strop. I'll only be doing local handicap racing so I doubt anyone will care.

The spars are Proctor, circa 1975 (remember gold anodising?!)  the boom has a series of s/s tubes through it to which ropes strops are spliced with the blocks attached. At present they are positioned for sheeting off the back end of the case. I actually prefer aft sheeting so I can hold sheet and tiller with one hand.
One hull good, two hulls better.

Hold the tiller extension across your chest and you can hold both with one hand plus the added advantage of being able to sheet in hand over hand. I can't think of any advantage* to an aft mainsheet, I hated it in my Heron when I was 12/13 and tolerated it in the Ent in my 30s but, for me, a centre led mainsheet is better in every way.


* I've just thought of one, you can tack facing backwards with both sheet and tiller in front of you which is slightly more intuitive for beginners.

You do need to tell your club you are sailing with the boat out of class though.

The current setup is as follows (If I tried to photograph it today I'd be somewhere on Dartmoor in short order!)

Sheet attached to becket on traveller - to block near mid-boom - back to block on traveller - up to second boom block just aft of other one - down to helmsman's hand. Hope that makes sense.

Ok that is how I had visualised it. I must admit I'd be inclined to bin the traveller and use rope strops with a block and cleat fixed where the traveller has been removed but why not just try it as is and see if it works before making a decision to do some extra work?

Never sailed a 420 but I recommend looking at what the top 420s have and replicating their system. Copying is the quickest way to get better.

Aft main, OK for cruising, off the boom sheeting is the work of the devil.

Love aft sheeting. Grew up with it. It leaves more space in a boat to move around, means you don't have to move aft tacking in light winds, and give far better purchase. Less control gybing in a breeze, though.
Off boom seems to work for some boats and not others. All to do with ergonomics, I guess. For instance, in a Minisail, it makes sense if sitting on a sliding seat, but not if lower down on the side deck in the standard boat.

I sail my 300 from the floor block, personal preference.
