We have O Day 39 number 81 1984 that we bought March 2006. Now named Dror, was Sparrow.
Great Boat, have spent 4 years unmuddling it.
Numerous projects including large holding tank, solar panels, refrigeration, new water heater, new cushions, track on mast for spinnaker pole, new standing and running rigging, lifelines, windlass and more.
Also stripped the bottom and epoxy coated last spring.
Happy to help with advice. email@example.com

So far only has solar panels but working on the rest.
