MARTYN WORMS
CEO
In 1978 Martyn started his maritime career as a Partner at R.B. Hunt & Partners, London – a ship brokerage firm involved in the sale & purchase, and chartering of commercial seagoing vessels. Martyn represented the firm at the Baltic Exchange and subsequently became a shipowner of cargo vessels.
His know-how of ship management and chartering, and his interest in superyachts naturally led Martyn to establish Camberley International over a decade ago.
Born and raised in The Netherlands he moved thereupon to warmer climes to further his entrepreneurial instincts, becoming an industry veteran known for his straight-talking style and integrity.
ROY POSTHUMA
BROKER
Roy Posthuma is a Charter & Sales Broker at Camberley International, specializing in luxury yacht charters, yacht sales, and yacht acquisitions.
Based in Italy, he works with clients from around the world, arranging bespoke superyacht experiences throughout the Mediterranean, the Caribbean, and other leading yachting destinations.
Roy believes exceptional service extends far beyond selecting the right yacht. Whenever possible, he personally welcomes clients at embarkation, ensuring every detail is in place so the charterer can relax and enjoy their time on board from the very first moment. His hands-on approach, honest advice, and attention to detail have earned the trust of clients who return year after year.
Whether helping a family plan a memorable yacht charter or guiding a client through the purchase or sale of a yacht, he is committed to providing expert advice, complete discretion, and a seamless experience from first enquiry to final delivery.
DARINA POSTHUMA
BROKER
Darina has always been drawn to complex projects and big experiences – first in management consulting and finance, then in Formula 1, and now in superyachts.
Before joining the superyacht industry, she spent over a decade in banking and management consulting across Europe, leading large-scale projects for international groups and the Formula 1 Sochi Grand Prix.
That taught her how to coordinate many moving parts, manage senior stakeholders, and still deliver a seamless experience.
Today she’s a Charter & Sales Broker at Camberley International, focused on family charters, explorer yachts, and off-the-beaten-track itineraries.
From heli-skiing and polar expeditions to quiet weeks in the Mediterranean, the Caribbean and other destinations, her role is to make ambitious trips feel safe, structured, and effortless for her clients.
She works with those who value privacy, clear communication and honest advice and takes time to understand how clients like to travel, match them with the right yacht, captain and crew, and stay closely in touch from the first idea until they’re home again.
