At Prescon Associates, our prowess is defined by our experience.

The founder, Graeme Preston, has over 25 years experience in the maritime and superyacht industries, comprising hands-on operational and extensive project involvement, with the past decade spent supervising the construction of some of the world’s largest and most luxurious yachts built to date.

From humble beginnings as a commissioning engineer on the east coast of Australia to scrutinizing the extreme conditions provoked during the commissioning and sea trials of a newly constructed vessel, having resurrected flooded engine rooms in the midst of Hurricane Katrina, Graeme knows first-hand what can go wrong at sea.

Prescon Associates’ core values – of Independence, Collaboration and Perfection – enable us to deliver the very best for our clients, and are why owners can trust us to support them through the process of purchasing, building or refitting their vessel.

Independence Whether it be due diligence before purchasing an existing yacht, the development, construction and delivery of a new build, or the planning and completion of a refit project, we work independently as the owner’s representatives acting solely to protect their interests.

Collaboration Collaborating from inception to delivery with exterior and interior designers, shipyards, and naval architects, our technical guidance provides practical certainty for our clients during the various stages of purchase, refit, or design and construction of their vessel.

Perfection As owner’s representatives, we have a reputation for not accepting anything less than perfection. We go above and beyond at all stages of our engagement to deliver the client’s expectations, whilst maximizing the value of their asset.


Our associates are an international team of carefully selected and highly experienced technical consultants, owner’s representatives and marine surveyors providing a range of bespoke professional services to owners, their representatives and crew, yacht management companies, and some of the worlds leading shipyards.
