Aquarius Arc-22 Information, Review, Specs

Sailing Performance & Handling

The sailing characteristics of the ARC-22 are defined by its immense stability and a "point-and-shoot" helm response that belies its 22-foot length. Because the boat features a beam significantly wider than traditional catamarans of this class—often reaching 12 feet depending on the specific production year and configuration—it offers a massive righting moment. This allows the crew to keep the boat flat and accelerate in wind conditions that would force smaller cats to depower. The hull design incorporates a high-aspect-ratio, deep-V shape that eliminates the need for daggerboards, a signature Bill Roberts design element intended to reduce underwater complexity and drag.

Handling is further enhanced by a sophisticated wing mast and a self-tacking jib system, which simplifies tacking maneuvers for the two-person crew. As noted in technical discussions by the manufacturer, the ARC-22 utilizes a specialized rudder system featuring NACA 63 series foils, providing precise control even at the high speeds the boat is known for—often exceeding 25 knots in favorable conditions. Owners frequently report that the boat feels remarkably "planted" on the water, with the extra buoyancy in the bows preventing the pitch-pole tendencies common in narrower high-performance catamarans.

Popular Mentions & Media

The ARC-22 has secured a legendary status within the ultra-distance catamaran racing circuit. It has been a consistent presence and frequent podium finisher in grueling events like the Great Florida Bank Race and various iterations of the Worrell 1000. Its reputation as a "distance eater" is cemented by its ability to maintain high average speeds over long legs of open water. The model is often discussed in performance-sailing editorials as the benchmark for what is possible when beach cat design principles are scaled up to the limit of trailerable dimensions.

Known Issues & Buyer’s Checklist

Prospective buyers of a used ARC-22 must focus on the structural integrity of the bridge deck and beam attachment points. Due to the extreme beam-to-length ratio, the aluminum cross-beams and the dolphin striker undergo significant torsional stress.

• Beam Bolt Integrity: Inspect the mounting points where the oversized beams meet the hulls. Any signs of elongated holes or spider-cracking in the fiberglass around the beam beds may indicate the boat has been pushed hard in heavy seas.
• Mast and Rigging: The ARC-22 features a tall, powerful wing mast. Buyers should check the mast base and the rotation limiters for wear, as the forces generated by the large mainsail are substantial.
• Hull Scouring: Because the boat lacks daggerboards, the hulls themselves provide the lateral resistance. Check the bottom of the "V" hulls for excessive abrasion or thin spots caused by beaching or dragging on sand.
• Trampoline Tension: The large surface area of the trampoline means that high-quality, high-tension materials are required. Ensure the hiking straps and lacing points are not frayed, as a failure here can be dangerous given the boat's speed.

Community & Resources

The primary hub for technical support and owner interaction is the Aquarius Sail Owners Forum. This community is highly technical, reflecting the nature of the boat itself, and provides a wealth of information regarding tuning the wing mast, optimizing sail trim for different wind ranges, and managing the logistics of trailering a boat with an over-width beam (which often requires a specialized tilting trailer). The manufacturer continues to provide parts and support from their Minnesota facility, ensuring that even older ARC-22 and SC-22 models remain seaworthy.

The Verdict

The Aquarius ARC-22 is not a casual weekend beach cat; it is a high-performance instrument designed for sailors who prioritize raw speed and technical refinement. While its width and power require a higher level of skill and logistical planning than smaller models, the rewards are unmatched in its class.

Pros

• Exceptional top-end speed and high-wind stability.
• Daggerboard-less design simplifies operation and reduces maintenance.
• Robust construction capable of enduring offshore distance races.
• Continued manufacturer support for parts and technical advice.

Cons

• The 12-foot beam necessitates a tilting trailer for legal road transport.
• The large sail area and high power-to-weight ratio can be unforgiving for novice sailors.
• The physical effort required to rig and de-rig a boat of this scale is significant.
