Astus 16.5 Information, Review, Specs

Sailing Performance & Handling

The influence of VPLP is most evident in the 16.5’s hull dynamics and performance ratios. Unlike earlier models that focused primarily on utility, the 16.5 features high-volume floats with a pronounced "V" shape in the main hull to reduce drag and improve tracking. The boat is offered in two distinct rigging configurations: the "Club" version, intended for leisure and sailing schools with a manageable 12m² sail plan, and the "Sport" version, which utilizes a more aggressive 17m² Mylar sail plan and carbon components.

Under sail, the 16.5 is characterized by its stiffness. Because the trimaran design provides a wide beam (3.8 meters when deployed), the boat exhibits very little heel compared to a monohull, making it an ideal platform for families or sailors transitioning away from the physical demands of trapezing. In light air, the boat benefits from its low displacement (approximately 210kg), while in fresher conditions, it demonstrates the "skimming" ability typical of VPLP designs. According to editorial reviews by Voiles et Voiliers, the boat tracks exceptionally well upwind for a multihull of its size, though its true strength lies on a reach where the gennaker can be deployed from the retractable bowsprit. The telescopic carbon beams allow the sailor to adjust the beam width, though they are primarily intended to be fully extended for sailing and fully retracted for docking or trailering.

Popular Mentions & Media

The Astus 16.5 gained significant international attention shortly after its debut, earning a nomination for the prestigious European Yacht of the Year in 2016 in the "Special Yacht" category. It was praised by the jury for its democratization of the trimaran concept, making VPLP-level performance accessible to the average trailer-sailor. The model has also been a frequent highlight at the Grand Pavois La Rochelle and the Dusseldorf Boat Show, where it is often cited as the benchmark for entry-level performance multihulls.

Known Issues & Buyer’s Checklist

While the Astus 16.5 is built for simplicity, there are several technical areas that prospective buyers should scrutinize, particularly regarding the telescopic beam system.

• Telescopic Beam Friction: The carbon beams slide into the main hull to reduce the beam for transport. Over time, salt crystals and fine sand can accumulate in the sleeves, leading to abrasion or jamming. Buyers should operate the beams to ensure they slide smoothly and check for deep scoring on the carbon surfaces.
• Trampoline Tension: The trampolines provide vital deck space but are subject to UV degradation and stretching. Inspect the hiking straps and the lacing points on the floats for signs of fraying or fiberglass stress cracks where the lacing eyes are mounted.
• Centerboard Trunk: As a beachable craft, the 16.5 is often run onto sand. Check the pivoting centerboard and the trunk for impact damage or "star" grazing in the gelcoat, which can indicate heavy groundings that might compromise the laminate.
• Rudder Assembly: The kick-up rudder is essential for shallow-water operation. Ensure the pivot mechanism is tight and that the pintles and gudgeons have not developed excessive play, which can lead to a "vibrating" helm at high speeds.

Community & Resources

Owners of the 16.5 benefit from an active and technically-minded community centered around the Astus Boats Club. This association serves as a primary hub for sharing tuning guides, organizing regional raids (long-distance coastal races), and providing feedback to the shipyard for future iterations. In North America and various European regions, authorized dealers often host "demo days" that focus on the specific rigging nuances of the VPLP-designed fleet.

The Verdict

The Astus 16.5 is a masterclass in compact naval architecture, successfully shrinking the performance of a racing multihull into a package that can be parked in a standard garage. It serves as a compelling alternative to beach cats for those who want to stay dry and stable without sacrificing the thrill of double-digit speeds.

Pros:

• Ease of Transport: The telescopic beam system and lightweight hull make it one of the easiest multihulls to trailer and launch.
• VPLP Pedigree: Superior hull shapes and sail handling compared to most boats in the sub-20-foot category.
• Versatility: The "Club" and "Sport" variants allow buyers to choose between a forgiving family boat and a technical racer.

Cons:

• Storage Limitations: As an open boat, there is virtually no dry storage for long-distance trekking.
• Cockpit Space: While it can technically carry up to four people (Category D), it becomes cramped quickly; it is ideally sailed with two adults.
• Maintenance: The telescopic beams require diligent freshwater rinsing to prevent long-term wear and seizing.
