O'Day 40: Design, Performance and Ownership Guide
With an LOA of 39'7", a beam of 12'7" and masthead rig standing roughly 51'6" above the deck, the O’Day 40 requires careful berth planning: marinas must offer sufficient LOA and mast clearance, channel depths must accommodate either the 6'8" fin keel or the 4'11" wing keel, and haul-out logistics demand crane capacity for a near 18,000 lb displacement hull.
