Astus 20.5

Astus 20.5 Coastal Cruiser


The Astus 20.5 coastal cruiser was developed in collaboration with VPLP design and was launched in 2018 as an upgrade from the Astus 20.2 model. The Astus 20.5 trimaran is ideal as a day or weekend sailor with sporty and stable sailing performance thanks to the 930 L floats. Bow spray is reduced by the redesigned hull shape and wavepiercer floats. The cockpit is spacious and two trampolines increase the living space on deck. The cabin has a wide entrance and centerboard box is placed off-center for convenient entrance. The v-bed offers a double berth, with two cabin benches (possibly berths for children) which can also be used as storage space. Draft is variable due to the pivoting centerboard and rudder, which make drying out possible. The floats can be extended and retracted by telescopic beams and therefore do not need to be disassembled for transport. The mast can be raised by hand using a mast lowering system*. The Astus 20.5 can be adjusted to the desired sailing style with various options. The sports* version has for example a vacuum infusion hull, mainsail and jib with larger surface in Aramid Black Technora, sports gennaker with winch, traveler, tiller extension and sports stickers.
