There is a section in the handbook on hauling out and storage ashore - end of section 9 in the handbook for my 33 built in the same year as your boat. Essentially says the same as I suggested but in more detail. I have used many different yards over the years (as well as being in charge of one for a time) and always found it best to leave it to the operators who know their machinery and cradles/supports. I keep my boat in a club and members have to provide their own cradles so most use adjustable cradles that can be dismantled and stored off site. I share with another member who has a Hanse370E and the staff adjust the cradle depending on which boat is in it, first resting on the keel and adjusting the level so it slopes slightly to the stern allowing water to drain and then bringing up the 3 supports on each side to keep it level and support the hull from movement. We have a Wise 20T travel hoist and the slings can be adjusted fore and aft to get the balance right so the boat is lifted and carried level. We have about 500 boats in the club varying from 20' dayboats to 40'+ cruisers, mostly sail. All very safe a free of drama.
