From the Powerboat Guide

An extremely popular yacht (over 50 were built) with a beautiful European profile and extravagant accommodations, the 70 CMY is one of the most luxurious production yachts ever offered by Hatteras. She’s basically a 65 MY with a cockpit addition (the extra hull length allows for an additional 426 gallons of fuel beneath the cockpit sole). Like most of the newer Hatteras motor yachts, the floorplan is arranged with the galley and dinette on the deckhouse level. The spacious fullwidth salon (no side decks) is extended well aft, leaving only a small afterdeck overlooking the cockpit. The wheelhouse and galley are both enclosed in this layout and separated from the salon. (Note that many 70 CMYs have been semi-customized at the factory to meet an individual owner’s requirements.) Twin 870-hp 12V71s will cruise the 70 Cockpit MY at 17 knots.
