Astus 24 Information, Review, Specs

Sailing Performance & Handling

The Astus 24 is characterized by its remarkable stability-to-weight ratio. With a beam of 5.25 meters when fully extended, the boat provides a wide, secure platform that allows for high-average speeds with minimal heel—a primary draw for those transitioning from monohulls. According to editorial tests by Multihulls World, the boat features fine hulls at the waterline and a chined central hull design that promotes early planing while maintaining interior volume.

Under sail, the 24 feels light and responsive, particularly in its "Sport" configuration which features carbon beams and an increased sail area (25.5 m² mainsail compared to the 22 m² leisure version). The telescopic beam system, a signature Astus Boats feature, allows the floats to slide inward rather than folding vertically or swinging. This keeps the floats oriented correctly in the water even when retracted, though it is primarily intended for harbor maneuvering rather than sailing in the retracted position. Handling is further simplified by a pivoting centerboard and rudder, which permit sailing in shallow waters and effortless beaching.

Interior Comfort & Variations

For a trimaran of this size, the interior of the Astus 24 is surprisingly habitable, optimized for "nautical camping" and short coastal hops. The central hull’s chined design creates a beamier cabin than found on many narrow-hull competitors. The layout includes a V-berth in the bow, two settee berths in the main cabin, and a dedicated galley area. It is one of the few boats in this class to offer a separate space for a chemical toilet in the forward cabin, a feature that significantly improves cruising comfort for families.

The manufacturer offered two primary versions: the "Leisure" and the "Sport." The Sport version utilizes carbon fiber for the telescopic beams and rigging, reducing weight aloft and increasing the boat’s stiffness and speed potential. Interior materials are functional and lightweight, favoring molded fiberglass finishes that are easy to clean after a week of salty coastal cruising. The large trampolines effectively double the usable "deck" space, providing a massive area for lounging while at anchor.

Popular Mentions & Media

The Astus 24 gained international recognition following its 2015 European Yacht of the Year nomination. It has been frequently compared to the Dragonfly 25 in major European sailing publications, often noted as the more accessible and utilitarian alternative to the high-spec Danish designs. Its appearance at major boat shows like the Salon Nautique de Paris helped establish the French "nomadic" sailing culture, where owners tow their vessels across the continent to reach different cruising grounds.

Known Issues & Buyer’s Checklist

Prospective buyers of a pre-owned Astus 24 should focus their inspection on the mechanics of the telescopic system and the integrity of the multihull-specific rigging.

• Telescopic Beam Binding: The sliding carbon or aluminum beams can bind if salt, sand, or grime accumulates in the tracks. Inspect for smooth operation and look for signs of excessive wear or scoring on the beam surfaces.
• Rigging Loads: Trimarans experience higher rig tensions than monohulls because they do not heel to dissipate wind gust energy. Closely examine the shroud attachments and the mast base for spider cracking or deformation.
• Trampoline Tension: The trampolines are vital for both safety and structural ergonomics. Check for UV degradation, fraying at the attachment points, and ensure the lacing remains taut.
• Deck-to-Hull Joint: Astus utilizes a solid fiberglass external hull-to-deck joint which acts as a rub rail. Inspect this area for impact damage, especially near the beam housing, where docking stresses are highest.
• Centerboard Trunk: Given the boat’s beaching capability, the centerboard and its trunk should be checked for impact damage or debris that might hinder the board’s movement.

Community & Resources

Owners often participate in the Astus Boats Club, a French-based association that organizes rallies and technical exchanges. While much of the primary documentation is in French, the community is welcoming to international owners, providing a wealth of knowledge on rigging optimizations and towing setups. Technical support and original parts are still managed by the shipyard in Brech, France.

The Verdict

The Astus 24 is a versatile, high-performance cruiser that successfully bridges the gap between a weekend daysailer and a dedicated coastal voyager.

Pros:

• True Portability: Retracts to 2.55m, making it legal for road transport without special permits.
• Ease of Launching: The pivoting foils and telescopic beams allow for quick setup and shallow-water access.
• Stability: Large 1,300-liter floats provide a very high level of safety and upright sailing.
• Habitability: Offers four berths and a toilet, rare for a performance-oriented 24-foot multihull.

Cons:

• Finish Quality: Earlier models can feel somewhat "utilitarian" or "rustic" compared to high-end cruisers.
• Beam Maintenance: The telescopic system requires regular cleaning and lubrication to prevent sticking.
• Performance Sensitivity: While fast, the light displacement makes it sensitive to heavy loading; too much gear can noticeably dull the boat's "spark."
