To get good tension on the forestay, it might be worth fitting a backstay..... Although not part of the rig 'as designed'. On Moonspinner we have a 4mm (i think 7x19 because its very flexible) backstay with split tails secured to tangs bolted under the pushpit staunchions on the transom. It doesnt need to be wound down so tight as to upset the balance of the standard rigging but it does keep forestay tension up when hard on the wind especially. It could also be easily fitted with a tensioner if you want to race....
If you are using a roller reefing foressail, I would suggest its even more important to maintain the 'line' of the forestay, especially if the furler uses a tubular alloy foil. My own thoughts are that the flexible foil type may be better suited to the Seal 22. Hood make a light flexible one (Seaflex), harken make a flexible one too and i'm sure other companies also. I have just fitted a Hood Seaflex and will give some feedback (if you want) when i've given it a good testing, although i'm still waiting for a sail at the moment and am temporarily using my original 'hank on' sails with an additional flying forestay rigged just to clear the roller drum....
