Windermere unveils new sustainable GT Mono Light class
Windermere’s third sustainable race day introduced a new national class and underlined growing momentum behind lower-carbon powerboat racing.
Being crafted from aluminium, the vessels are very light weight and require less horsepower to propel them through the water, which results in a more efficient engine-boat combination as well as reducing the cost of ownership – both initially and throughout the vessel’s life. The aluminium hulls also offer an advantageous rigidity, allowing the operator to confidently handle their boat in choppier waters and enjoy enhanced manoeuvrability.
All new YAMs are available with a range of Yamaha outboards and a selection of seating configurations. An optional bench seat and console is available on the TAf models. While the bench seat offers comfortable seating and storage beneath, the console gives added protection and the option of a remote throttle and additional navigation electronics as required. For additional seating and storage, a cushioned seat is also available adjacent to the console.
Suitable for family weekend adventures, the 350TAf has the capacity to carry four adults and one child. It is 350cm in length overall, has a beam of 160cm and the bareboat weight is 72kg. Engine options include a lightweight Yamaha 25hp. The 310TAf, at 307cm in length with a beam of 160cm, is suitable for action and adventure or hosting a fishing expedition. Engine options include the latest Yamaha 20hp featuring battery-less EFI, with the vessel weighing 60kg.
The 270TAf is the most compact boat in this range, with engine options including the Yamaha 8hp and 6hp. This boat measures 265cm (total length) and has a 159cm beam. The bareboat weight is 41.5kg, making it easy to handle out of the water. It offers a three-adult, one-child capacity.
Meanwhile, Yamaha’s STi range of craft has also been renamed the ‘Air’ range. The range comprises the YAM 240 Air, 275 Air and 310 Air-V.
