Mines 3 to 1 but requires a bit of a winch strugle when lifing quickly. To make 4 to 1 will require an extra upright with the rope fixed either to the keel or on to a becket on the triple block. I assume a triple is the maximine?

Please will other 21 owners let me know what their purchase systems are like

Thanks

I think my layout is as supplied with a 2-sheave block at the top and a 3-sheave block on the keel. But I replaced the blocks with ball-bearing blocks (at vast expense!) and now I can heave the keel up without needing the winch - just!
