I'm sure it was just a typo but you have a superseal 26, not a 22!
The original set up for the man sheet was a purchase on the coachroof bar, leading aft along the boom and dropping to a swivel jammer in the cockpit. This is shown in the 26/27 handbook (available from Di Drew the regalia officer).
Rascal my 26 has a track set across the forward end of the cockpit, giving a clearer cockpit and much more control/adjustment for the main. It's also easy to park to the side when not sailing.
