The Relationship Between Williams and YANMAR Gets Stronger Every Year

From a young age, Mathew and John Hornsby were always encouraged to play on the river by their parents. In doing so, the brothers developed a love for the water that continues to this day. As young boys – and best friends – little did they know this early encouragement would sow the seeds for a business idea that would become their true vocation.

Driven by ambition and a desire to work together, they built their first boat in their mother’s garden shed and displayed it at the Henley-on-Thames boat show. They called the fledgling company ‘Williams’ (their mother’s maiden name) and the beautiful 20-foot mahogany boat called ‘Jade’ was sold for use on the Italian lakes. Their next boat, ‘Izana’, also was quickly sold and ended up on the French Riviera. Both craft are still in operation today.

Company Profile

The remarkable story of Williams Jet Tenders (Williams) began when two young brothers turned a passion for the water into a thriving tender business with quality engineering and craftsmanship at its core. From its first vessel built in a garden shed, Williams has become the UK’s most prolific boat builder, outputting around 1,000 units a year.

During our initial research, we looked at several engine manufacturers. It quickly became apparent that the YANMAR range was well engineered, with an excellent power-to-weight ratio. Since we began our working relationship with YANMAR, we’ve designed multiple boats using YANMAR power packages. Our relationship gets stronger every year.
