New construction design from Patrick Bray of Bray Yacht Design and Research featured in Yachts International magazine 2011.
OVERVIEW 42m OCEAN MOTORYACHT
This long-range motoryacht will be based primarily in the Mediterranean for a client who enjoys extensive outdoor activities. There is spacious accommodation for 14 guests and up to 10 crewmembers. It has a super fuel-efficient, semi-displacement hull form that is a progression of our extensively tank tested hull technology to ensure superior powering characteristics and seakeeping. The hull is a conically projected, double chined form with wide spray knocker, flared bow, and a transom stern. It is longitudinally framed with wide spaced transverse frames for maximum strength and ease of construction.
Advanced technology appendages, including a bulbous bow, midship bulb, stern bulb, fixed/active stabilizers, and a bi-foil under each propeller, are the features that make this vessel unique. In addition these features give the vessel superior seakeeping ability as well as having double the range of stability of other vessels.
This vessel has in excess of a Trans-Atlantic range at 12 knot cruise as well as being capable of higher semi-displacement speeds for local cruising.

The fresh water tanks are non-integral stainless steel. All the other tanks are integral under the lower sole.
PRESSURE WATER SYSTEM
Providing 40 – 60 p.s.i. continuous pressure.
The entire hull is designed without any compound curves eliminating the need for any stretch forming of plates. The double chined hull is conically projected so that large sheets of steel may be applied without any need for forming or machine bending. The transverse frames are flanged plate spaced at 1.067m (42”) centers with longitudinals sprung into place at 0.46m (18”) centers. There is approx. 136,100 kg (300,000 lbs.) of steel in the hull and 22,750 kg (50,000 lbs.) of fiberglass in the vessel’s superstructure.
Maximum sound levels shall not exceed the following levels (dB A weighted) at 12 knots cruise speed:
Owner’s Accommodation - 55
Guest Accommodation - 60
Public rooms - 60
Recreational decks - 65
