Astus 20.2 Information, Review, Specs

Sailing Performance & Handling

The sailing philosophy of the Astus 20.2 is rooted in high power-to-weight ratios and the inherent stability of a multihull. With a displacement of approximately 350kg to 420kg depending on the version, the boat is exceptionally light, allowing it to plane quickly in moderate breezes. In editorial testing, Yachting Monthly noted a significant performance delta between the "Standard" and "Sport" versions, with the latter benefiting from a larger sail plan, Mylar sails, and a carbon mast.

Under sail, the boat tracks with precision thanks to its deep pivoting centerboard and high-aspect rudder. Unlike many monohulls of similar length, the 20.2 maintains a very flat sailing attitude, which reduces crew fatigue on long coastal passages. Handling is characterized by responsiveness; the boat can be tacked easily, though like most light trimarans, it requires the jib to be back-filled momentarily in light air to ensure the bows pass through the eye of the wind. The "XL" variant of the 20.2 hull is particularly noted for its increased buoyancy in the floats (taller and higher volume), which allows for harder driving in offshore conditions without the risk of burying the leeward bow.

Interior Comfort & Variations

While the Astus 20.2 is primarily a performance-oriented daysailer, its interior is designed for "nautical camping" or weekend coastal hopping. The cabin is minimalist, offering a V-berth that can accommodate two adults, though headroom is limited and the space is best utilized for gear storage or shelter from the elements. The transition from the 20.1 to the 20.2 saw an increase in cabin volume, providing a slightly more usable "dry zone" for overnighting.

The model was offered in three primary configurations: the Leisure, the Standard, and the Sport. The Leisure version often featured a simplified rig and more robust, heavier construction suited for families or sailing schools. The Sport version, which remains the most sought-after on the secondary market, maximizes the hull's potential with increased sail area. Additionally, the XL version utilized the same main hull but integrated larger, higher-volume floats to improve righting moment and safety in heavy seas. The interior across all models remains spartan, emphasizing weight savings over luxury, with molded fiberglass finishes and basic textile cushions.

Known Issues & Buyer’s Checklist

Prospective buyers of a used Astus 20.2 should focus their inspection on the mechanical interfaces of the trimaran's unique folding system.

• Telescopic Beams: The carbon or aluminum beams slide into sleeves in the main hull. These can become jammed if sand or salt crystalizes inside. Inspect the sliders for deep scoring and ensure the locking pins engage securely without excessive play.
• Trampoline Tension and UV Damage: The trampolines provide a significant portion of the "deck" space. Check the hiking straps and the lacing eyes for sun degradation. Replacing these can be a significant hidden cost.
• Daggerboard Trunk: Given its trailerable nature, the 20.2 is often used in thin water. Inspect the trunk for stress cracks or impact damage, and ensure the pivoting mechanism for the centerboard and rudder operates smoothly.
• Gelcoat Stress: Check the areas where the beams meet the main hull for "spiderweb" cracking, which may indicate the boat has been driven hard in conditions exceeding its design parameters.

Community & Resources

The primary hub for technical knowledge and owner interaction is the Astus Boats Club, a dedicated association of owners that organizes rallies and maintains a repository of rigging guides and modification tips. While the community is centered in France, the club provides essential support for international owners seeking parts or specific maintenance advice for the Roulin-designed models.

The Verdict

The Astus 20.2 is a specialized tool for the adventurous sailor who refuses to be tethered to a single marina. It bridges the gap between a high-performance beach cat and a traditional cruising monohull, offering enough safety for coastal exploration with the speed to outrun most 30-footers.

Pros:

• Exceptional Versatility: The telescopic beams make it one of the easiest trimarans to trailer and store.
• Speed: Capable of double-digit speeds in moderate conditions, especially in the Sport configuration.
• Stability: The wide beam provides a secure platform for families compared to a heeling monohull.

Cons:

• Minimalist Accommodations: Not suitable for those seeking "creature comforts" or standing headroom.
• Low Freeboard: The boat can be "wet" in a chop, necessitating high-quality foul weather gear for the crew.
• Complexity: The telescoping system and trampoline lacing require more maintenance than a simple fixed-keel boat.
