Q: I've capsized and i don't have a righting line, what do I do?

Consider using the mainsheet; if it is long enough, tie the mainsheet, with alot of play so that the main and traveller are uncleated, at the rear cross beam, then run the line in between the shrouds to the front cross beam of the raised hull and tie it there. Holding the mainsheet as if it is a righting line.
