The story
The Hydra 450 is the original of ROTO's Hydra line, and Kewat moulds it in Naivasha. The catalogue lists it for fishing, family outings, professional work and rescue operations: one small boat for many kinds of day.
The front and rear benches lock, for the fuel tank and for your things. The transom is reinforced, with aluminium plates where the engine mounts. Choose a tiller outboard, or add the steering console and drive it from the wheel.
