Astus 20.5 Information, Review, Specs

Sailing Performance & Handling

The sailing dynamics of the Astus 20.5 are defined by its exceptional power-to-weight ratio and the stability provided by its VPLP-designed floats. In editorial testing by Yachting Monthly, the vessel demonstrated an ability to reach double-digit speeds with ease, often clocking between 10 and 15 knots in moderate breezes. The boat is offered in two distinct rigging configurations: the "Leisure" version, aimed at family day-sailing with a standard aluminum mast, and the "Sport" version, which features a carbon mast, high-performance sails, and an additional 5 square meters of sail area.

Because the floats possess significant buoyancy (approximately 930 liters each), the boat remains remarkably level even when pressed, which translates to a sense of security for less experienced crews. The handling is reported as "dinghy-like" due to its responsive transom-hung rudder and light displacement of roughly 490 kg. Owners often note that the boat tracks exceptionally well upwind for a trimaran of its size, a trait attributed to the efficient pivoting centerboard and the flared hull shape that keeps the bow from "digging in" during gusts.

Interior Comfort & Variations

For a vessel of its dimensions, the Astus 20.5 offers a surprisingly functional, albeit minimalist, interior. The cabin is designed primarily as a "shelter" or for "pocket cruising," providing enough space for two adults to sleep on a V-berth that extends under the cockpit. While the headroom is limited—making it more of a "sitting room" environment—it serves effectively for weekend excursions or as a dry storage area for gear.

The official Astus Boats specifications highlight the versatility of the layout, which can be customized with optional storage pockets and a small chemical toilet. The "Leisure" variant typically emphasizes comfort with more cockpit cushioning and simpler sail controls, whereas the "Sport" variant may strip away some amenities to save weight. It is important to note that while the 20.5 is the primary hull, the manufacturer occasionally produces "Infusion" versions that utilize vacuum-infusion construction to further reduce weight and increase hull stiffness for racing enthusiasts.

Popular Mentions & Media

The Astus 20.5 gained significant industry recognition shortly after its release, being nominated for the prestigious European Yacht of the Year award in 2018. This nomination solidified its status as a leader in the trailerable multihull category. Its design has been frequently cited in maritime journals as a benchmark for how VPLP’s "big boat" racing technology (seen in the trimarans like Banque Populaire) can be successfully scaled down for the recreational sailor.

Known Issues & Buyer’s Checklist

When inspecting a pre-owned Astus 20.5, the primary focus should be on the telescopic beam system and the integrity of the float attachments.

• Beam Friction and Wear: The carbon or aluminum beams slide into fiberglass sleeves. Over time, salt and grit can cause abrasion. Ensure the beams move smoothly and check for any structural "slop" or play in the fully extended position.
• Trampoline Tension: The trampolines provide a significant portion of the deck’s usable area. Look for UV degradation or fraying at the attachment points, as loose trampolines can compromise the feeling of safety while moving around the deck.
• Rudder Kick-up Mechanism: The 20.5 uses a kick-up rudder for beaching. The pivot point and the uphaul/downhaul lines should be checked for wear, as these are high-load components.
• Centerboard Trunk: As with many trailerable boats, the centerboard trunk can collect debris. Inspect the board for dings or swelling that might cause it to stick.

Community & Resources

The most active hub for owners and prospective buyers is the Astus Boats Club, a French-based association that organizes rallies and provides a technical forum for maintenance tips. While much of the primary documentation is in French, the club has a growing international membership due to the boat's expansion into the UK and US markets. Technical manuals and tuning guides for the VPLP hull are often distributed through authorized dealers who maintain close ties with the Brech-based shipyard.

The Verdict

The Astus 20.5 is a masterclass in compromise-free trailerable sailing, offering genuine multihull speeds in a package that can be managed by a single person.

Pros

• Exceptional Versatility: The telescopic beams make it one of the easiest trimarans to trail and store.
• VPLP Pedigree: High-performance hull design ensures superior speed and stability compared to older 20-foot multihulls.
• Safety: High buoyancy floats and a stable platform make it an excellent choice for coastal family cruising.

Cons

• Minimalist Interior: The cabin is best suited for storage or "glamping-style" overnighting rather than extended living.
• Price Point: High-tech features like carbon beams and VPLP design come at a premium compared to similarly sized monohull daysailers.
• Weight Sensitivity: Performance can drop noticeably if the boat is heavily loaded with cruising gear and multiple passengers.
