BACKGROUND
Patrick Bray's design and consultative responsibility has included all types of pleasure,
commercial, and special purpose vessels using fiberglass, foam cored and composite
fiberglass, wood epoxy, steel, and aluminium materials. Vessels embodying our direct
design, conversion, and construction participation are in use on both East and West Coasts
of Canada and the United States, Mexico, and The People's Republic of China. Interest in the
Company's work ranges from the Middle East, Europe, Australia, and South America.
Research and model testing is a big part of our work. We build plating models, models for
testing, and models for display. In house projects are ongoing at an average rate of two a
year. Our own development of fast pleasure craft includes model testing in Dalian and
Shanghai, P.R. of China, as well as here at home. Work is also being carried out on
appendages for improving rolling and pitching motions of long range motoryachts while at the
same time improving fuel economy. In addition we are working on twin keel sailing yachts in
Vancouver, B.C., evaluation and analysis of ballast/displacement ratios, as well as the
development of new building systems. Participation in testing programs has included work on
Boeing Marine System's Jet Foil into Dover Harbor Project, military research on 100 knot
planing hulls, and S.W.A.T.H.s.
Military work includes contract work for the Department of National Defense, Viking
America Inc., and Peter Hatfield & Assoc. Ltd.
Pleasure craft include award winning sailboats from 30 to 96 feet, motorsailers capable
of 14 to 18 knots, ranging in length from 27 to 95 feet, and world cruising long range motoryachts to 85 feet.
Trade talks have been arranged between various levels of the Canadian Government; and the
People's Republic of China both in China and Canada, and the Islamic Republic of Iran.
CONTRACTS TO OTHER COMPANIES
80 FOOT SAIL CATAMARAN
Designed with Robert Harris formerly of Harris & Heacock Ltd. (New York) to be built in
aluminium, as well as various other sail and motoryachts over a period of 8 years.
60 - 100 FOOT OCEANOGRAPHIC AND FISHERIES RESEARCH VESSELS
Designed and model tested with Peter Hatfield & Assoc. in steel, aluminium, and
fiberglass for various governments and agencies.
POLAR 8 ICE BREAKER
World's largest ice breaker designed with Peter Hatfield in co-operation with Sandwell-Swan
Wooster.
NATIONAL DEFENSE
Repair and conversion of military vessels in Esquimalt, B.C.
M.V. BROCKTON
Working drawings and project management for a 38 foot aluminum port authority vessel for
Vancouver Harbor Patrol.
FISHERIES PATROL VESSELS
Work on the 58 foot Banjo Reef series of Fisheries Patrol Vessels for Peter Hatfield, as
well as a variety of commercial and pleasure craft over a period of 6 years.
THE PEOPLE'S REPUBLIC OF CHINA
Work at the Bei Hai Shipyard, city of Qingdao with the China State Shipbuilding Corp. to
establish a yacht building industry. This project was halted after ten years preparation, in
the fifth month of construction, and we evacuated the city the weekend of the Tiananmen
Square Massacre.
ORGANIZATION AND TEACHING OF BOAT BUILDING CLASSES
Night schools in Vancouver and White Rock. The courses involved lofting, costing out, blue
print reading, and construction of an 8 foot dinghy for each student in the class. A
specific design was developed for this class which would teach the required material yet be
inexpensive and quick to build.
ORGANIZATION AND TEACHING OF POWER SQUADRON COURSES
As a volunteer instructor for the Canadian Power Squadron taught several courses from Basic
Boating to Seamanship Sail. As Lieutenant Commander in charge of the training program ran
training courses.
VARIOUS BUILDERS
Work for various yacht builders including West Bay and Crescent Beach Boat Builders on
motoryachts from 58 feet to 115 feet. Work included model testing, shop drawings, piping
systems, and knowledge of Bureau Verities and ABS. Required to work directly with the
surveyors of BV and ABS for certification of motoryachts over 100 feet.
IN HOUSE PROJECTS SAIL
BRAY 7.5 24'-6" innovative, performance one design
sailboat suitable for one-off and homebuilding. Utilizes our unique construction method
called the New Epoxy Wood System (NEWS). The designed proved to be faster and more roomy
than the J24 (the target vessel).
JENNIFER 32'-3" offshore sailing cruiser
designed for Cruising World's Design Competition. Received a best mention. Incorporated many
safety features and qualities specific to a vessel intended for extended ocean passage
making. Inquiries have been received from Yugoslavia, Panape, and the USA.
SUSAN 35'-9" steel sail boat designed for
one-off construction. This vessel utilizing the information gained from our studies into low
ballast ratio used on previous projects. This allow the boat to have a moderate displacement
despite the heavy material. Performance was very good and received praise for handling and
interior space planning.
96 FOOT KETCH Designed in round bilge steel. We
were able to reduce material and construction costs on this vessel by using our low ballast
ratio hull form.
MOTORSAILERS FREESTYLE
27 27'-0" unusual, concept motor/sailing vessel, intended to be used as a total
recreational vehicle. On the trailer it could be easily boarded and used as an RV, in the
water it was easily rigged and sailed by a neophyte. With the 50 h.p. outboard the top speed
was 18 knots and could tow a water skier. The mast was a bipod.
11.5 METRE 38'-0" motorsailer model tested
to 14 knots using 75 s.h.p. This vessel also explored the use of twin keels to give
increased performance and shallow draft. The test results where very encouraging but more
work remains to be done.
EMERALD CITY
92'-0" motorsailer combining the grace of sail and the accommodation and amenities of a
motoryacht. Speed under power is 18 knots.
MOTORYACHTS
11.6m SPORTFISHERMAN
38'-0" power boat. Model tested for fuel efficiency and seakeeping, it explored the use
of a double chined hull form with deep lift strakes. The resistance curve is dead flat
between 14 and 35 knots with the trim angle changing only 1/2 a degree over that range.
Seakeeping qualities were also exceptional.
HI DAD
57'-0" long range motoryacht designed for extensive offshore cruising. Uses twin keels
for roll and pitch dampening while reducing resistance at cruising speed. Has an 8,000 mile
range at 9 knots and a 15,000 mile range at 6 knots. Performance and tracking in 12 foot
following seas was found to be very good.
PROPOSALS Various proposals for motoryachts
between 60 and 130 feet have been prepared for clients and builders including West Bay Son
Ship and Crescent Beach Boatbuilders.
SPECIALIZED SERVICES
As the need arises for special skills not available through the
Company, the services of outside consultants are engaged. On many occasion a consortium of
companies is required to achieve a desired design goal. At Bray Yacht Design we are
familiar with and/or have worked with many of the prominent designers, engineers, and
builders in North America.
Outside services and design firms utilized include Robert B. Harris Ltd., Peter S.
Hatfield Ltd., Alfonso M. Sotres & Assoc. Ltd., Diana Yacht Design Inc., and Roddan Engineering.
Specialized structural, heating, ventilation, electrical, and mechanical engineering
design and consultative services are also engaged as required.
Open water model studies can be undertaken according to the specific project needs with
our own equipment, with or without the cooperation of other facilities. Tank testing studies
as required to fulfill design requirements in other selected facilities are also available.
Propeller and nozzle design as well as propulsion, resistance, performance prediction,
and calculations can all be made available.
Computer generated hydrostatic cross curves, righting arm, intact stability, floodable
length, and tank capacity calculations for virtually any type of vessel are standard as
required.
