Is the forestay 20 years old? if it is you might want to replace that before you take off for a long time. I have a Hood Rolling Furling and it came down on the last sail... nothing more frustrating than having your half rolled jib laying the length of your deck.
If your rigging is 20 years old make sure you inspect it. Look for small cracks on the turnbuckels and rust where the wire is fastened together. I later found rust and even some brooken strands on some of the lines. Opps... I guess I didn't want to see it before.
