Persons behind Esthec

By the age of 4, Rientz W. Bol developed his ‘sea legs’ on board sailing yachts. After ‘the Optimist’ and ‘Laser Class’ he participated  in the ¾ ton World Championships and a ‘Trans-Atlantic’  During university (Master of Science) he focused on rowing, but he maintained his sailing activities.  In 2008 he won the Copa del Rey, with the Esthec equipped Swan 45 ‘No Limits’, as well as the European Championships and the Memorial Giorgio Falck. His passion for sailing and the accompanying yachts remains intact, while being the director of a Dutch company producing composite materials (see ‘The story behind Esthec).

Marcel van der Spek began quite differently. He started his career in the professionally organised automotive industry. After setting up a European network of 9 branches from scratch, he knew what his talents were. He joined Rientz W. Bol in the new, but rapidly growing Esthec in order to make this company a worldwide success.  Marcel became co-founder of Esthec.  In addition to sales and organisation, he was born for operating on an international scale.
