Nigel Irens 31 ft LDL Motor Launch 2017 - Sold

WILHELMINA was conceived as a test vessel to further Nigel Irens's ongoing development of the 'LDL' (Low Displacement / Length ratio) hull form, based on the simple premise: "how much power do you really need?"... The timber-built WILHELMINA has demonstrated LDL's advantages by undertaking a number of long-range passages. A recently completed 94 nautical mile passage from Cowes, Isle of Wight, to Dartmouth, Devon, was accomplished at an average speed of 11 knots (benefitting from an average one knot fair tide). Fuel burned amounted to only 37 Litres - so 0.4 Litres per mile. WILHELMINA is eminently suitable for re-powering with a battery-powered electric motor. Apart from these remarkable numbers, WILHELMINA of course displays Nigel Irens's instantly recognisable styling to make the whole a most attractive, unique, and low carbon footprint offering. She has proven a much loved family day and weekend cruiser, exploring the coast and coves of Devon, and would be equally at home as a super efficient and striking superyacht tender.

The technology aims to explore the range of motor vessel speeds that are optimised to lie between that of a displacement hull and a fully planing hull. The objective of this initiative is to produce a vessel that offers:
- Substantially reduced fuel consumption
- A vastly increased range
- A reduction in noise and vibration
- A smooth curve of power/speed - virtually no 'hump' speed
- So, the ability to travel at any chosen speed always well under control
