Lead by founder Mark Tucker, Design Unlimited looks forward to new challenges and welcomes the opportunity to work alongside owners looking to realise their own distinctive visions. Cooperation lies at the core of everything that the studio achieves, and in many cases has resulted in enduring client relationships stretching across whole series of yachts.

Mark Tucker – CEO

With over 30 years of experience Mark is a well-known and respected figure in the yacht interior design world.  Design Unlimited was founded in the Millennium year and the studio has become renowned for innovation and creativity, combined with technical understanding.  Early projects such as Visione, Sojana and Pink Gin V established the studio’s impressive design credentials and Mark’s own experience as both a dinghy and cruising enthusiast have assisted in the expansion of the studio’s extensive production yacht portfolio which includes work for Sunseeker International and Bavaria Yachtbau.

Mark is married to Julie and they have two children.  Mark’s passion for the water has led he and Julie to a long and varied sailing career. They currently compete in an RS400 and also sail a 42’ cruiser with the family.


Julie is a qualified legal executive but changed career in 2000 to join Mark in running Design Unlimited. Julie manages all the non-design aspects of the studio, including PR and finance. A career multi-tasker, Julie juggles work, children, boats, dog, cats, family and home with apparent ease and always a smile.
