Linssen 50 SL AC Variotop® The Linssen 50 SL AC Variotop® represents a more compact version of the Linssen 55 SL AC Variotop® and the little sister of the Grand Sturdy 500 AC Variotop®. With her three cabin layout, she comfortably accommodates six people. The generous saloon creates plenty of living space with a spacious galley and seating. Wheelhouse with Variotop® The most striking feature of the Variotop® is undoubtedly the wheelhouse. It is wonderfully heated and protected under the Variotop® when the weather is cooler, and open when the sun shines - but still protected from the wind - when weather conditions permit. By raising the electric helm seat to its highest position, you can raise yourself above the window area for a panoramic view.
