As reviewed in the August 2021 edition of Yachting Monthly!

Offering exhilarating performance yet easy to rig, handle and tow to your favourite sailing areas, the Astus 20.5 trimaran is now available for sale in the UK from Boats on Wheels. The latest model in the line of innovative Astus boats responds to a real demand for exciting but practical trailer sailers. The Astus 20.5 succeeds the popular Astus 20.2, of which 120 were sold. Described by Astus Boats as their Coastal Cruiser, the 20.5 is rapidly becoming their most successful trimaran to date. No wonder. As a result of its  partnership with world renowned naval architects, VPLP, Astus Boats have come up with a real head turner. Huge floats with wave piercing hulls placed further apart and forward give the new 20.5 a very contemporary look and a truly stable platform.  Blistering speeds can be achieved at a crew-friendly low angle of heel. Of course, with speed comes extended range. Previously out-of-reach destinations become a real possibility for day-trips or weekends thanks to a cabin for two featuring a long v-berth, plenty of storage and an off-set centre board for easy access.

Boats on Wheels is delighted to offer this exciting trimaran as we think that the 20.5 comes as an ideal trailer sailer package:

– High-performance with modern, sporty lines offering speeds of up to 20 knots reported!

– 930 litre floats which offer stability and a low level of heel

– Simple to rig and handle – single handed mast stepping for day-sailing is realistic

– Easy to tow – with the ‘Infusion’ built boat weighing in at only 490kg it can be towed by a Ford KA!

– Retractable floats and shallow draft provide limitless opportunities to explore new sailing areas

– Can be used as a day sailer or weekend cruiser with a long v-berth for overnight stays and masses of storage under the cockpit

– Flared hull for effective spray deflection

– Low cost of ownership – maintenance is minimal and garage or driveway storage is a realistic option

– Multiple options from ‘Leisure’ to ultralight ‘Infusion’ models and sport rigs to suit every sailing style

– Affordable prices, starting at only £29,950 inc VAT/ex works (all prices are subject to the prevailing exchange rate)

Don’t just take our word for it, read the review by David Harding of Yachting Monthly magazine who describes this exciting trimaran as ‘tremendous fun’!
