It's almost unheard of for us to encounter a boat which genuinely has the power to shake up the boating market. The new Greenline 33 Hybrid has exactly that potential.

As well as ‘normal' diesel engine propulsion, the coupe-like 33 has the ability to cruise along in almost complete silence using its electric motor/generator. Of course, the diesel option is faster (13.3 knots on test) but the electric motor pushed our prototype test boat at a perfectly respectable inland waterways cruising speed of 5.5 knots.

The 33's eco and hybrid credentials don't end there - there's also the option of an interlinked solar roof which helps to charge the big lithium-polymer battery bank, and which can also (allegedly) generate enough power on the sunniest of days to waft the 33 along at a self-sustaining 3.5 knots.

Irrespective of its performance and its hybrid and eco credentials, what makes the Greenline stand out from the crowd is its remarkably competitive price. Here is a voluminous, practical coupe that can be bought (without all the hybrid paraphernalia) for as little as £79,900 ex VAT.

Adding the electric motor/generator that elevates the 33 to hybrid status adds £20,000 ex VAT, but even that version kicks off at a remarkably competitive £117,383 inc UK VAT. So, unique and good value for money - now there's a novelty.
