I have been either designing or building sail and powerboats for over 36 years.  My involvement in the marine industry began as an apprentice boat builder in New Zealand working for my grandfather, a master shipwright.  I completed a full apprenticeship while at the Auckland Technical University and also earned a structural engineering and architecture associates degree.  Having practical experience in all facets of the building and design business and management roles make me uniquely qualified as a Naval Architect, Marine engineer and manager for the marine industry.


I bring to the market 26 years of international marine experience as an “all-around” yacht designer, devoting special attention to performance hull forms and engineering / mechanical design of components / production vessel design / interior design, general arrangements and styling to accommodate every client’s individual requirements.  I believe in making the design suit the function of the vessel while ensuring the styling complements the performance. Fore most to me is “the client satisfaction” from services rendered.  I am fully versed in Mac Surf, AutoCAD, Microsoft office programs and structural engineering programs.

Past experiences have included involvement with the design or re-design of many unique and interesting vessels, including an America’s Cup Yacht 1988 and passenger vessels for Walt Disney World Co.  As well as all engineering and structural styling for Walt Disney World’s Space mountain entrance and monorail system. Also, I am fully conversant with ABS, DNV, Lloyds, USCG and MCA requirements.
