Astus 20.5 Buyer's Guide
The Astus 20.5 is a 2018-season pocket trimaran from Astus Boats, designed by Jean-Hubert Pommois with VPLP, that folds its floats from a 4.50 m beam down to 2.48 m for trailing behind a normal car. On the used market it appeals to sailors wanting a light, trailerable multihull with real speed rather than enclosed cabin volume.
Layouts on the Used Market
Every example is a variable-beam trimaran with a narrow central hull and two retractable floats on sliding aluminium beams. Below, the hull is cosy: a seat either side, stowage around the companionway, and a spot for a chemical toilet under the aft berth, with a simple weight-saving finish. Above decks the trampolines each side form the real living space, and a tent can extend sleeping al fresco. Two factory layouts appear — a leisure model for family sailing and a Sport version with a vacuum-infused central hull and square-top mainsail for more sail area.
Equipment and Common Upgrades
Most boats carry Harken hardware and Sélden spars as standard, with a 2.5–5 hp outboard on an outboard transmission and a maximum 6 hp rated. The meaningful buyer-relevant choices are rig-related: the Sport's square-top main, or optional carbon and wing masts for less weight and more stiffness. Beyond that, the builder offered multiple personalization options, but the consequential themes for a shopper are sail-plan variant and mast material rather than creature-comfort add-ons.
What to Inspect
The known points from the review record are minor rather than structural. Yachting Monthly found the rigging process could be simplified, so check that the sliding beams, centreboard and mast-raising routine operate cleanly and that nothing has been improvised. The same review described a slightly stark interior finish and a simple, weight-driven fit-out, so expect bare surfaces rather than fault. The centreboard is offset to port to clear the centreline; confirm its trunk and pivot are sound.
Availability and Buyer's Takeaway
Used Astus 20.5 trimarans turn up in the British Virgin Islands, Austria, and the Netherlands. For a buyer, the checklist is short: confirm which version (leisure or Sport) and whether a carbon or wing mast is fitted; verify the float-sliding mechanism and centreboard trunk; and accept the minimal below-decks finish as design, not neglect. A folded width under the road gauge and sub-500 kg weight make transport and storage unusually painless for a sailing multihull.
