To swing a 2.2 ton keel there's not really any realistic alternative to hydraulics (and with a 3m draft there's also not really any realistic alternative to a swinging keel, but this is of course another discussion).
But for maneuvring sails there certainly are alternative solutions, starting with winches that are sufficiently sized for manual operation.
I know from experience (manipulating the keel when the boat is being lifted = no engine = no hydraulics) that the manual back-up (plan B) is very hard work
