The RS Cat 16 represents a modern evolution of the recreational multihull, engineered by RS Sailing to bridge the gap between fragile performance racing cats and heavy, unresponsive rotomoulded trainers. Launched to provide a more durable alternative to the classic beach cat, the RS Cat 16 utilizes a threelayer Comptec PE3 polyethylene construction, making it nearly impervious to the cosmetic and structural damage typical of beaching on rocky shorelines. It serves as the flagship of RS Sailing’s catamaran range, sitting above its smaller siblings, the RS Cat 12 and the RS Cat 14. All three models share a distinctive "chined" hull design, which provides significant reserve buoyancy and helps prevent the "pitchpole" tendencies often associated with older, narrowbow catamaran designs.

Sailing Performance & Handling

The handling of the RS Cat 16 is defined by its stability and the absence of daggerboards, which simplifies the sailing experience for intermediate sailors and training centers. According to technical specifications from RS Sailing, the boat is available in multiple rig configurations, including the "S" (Club) version and the "XL" (Performance) version, which adds a trapeze and a gennaker. The hull's high freeboard keeps the crew relatively dry compared to traditional low-profile cats, while the volume distribution in the bows allows the boat to ride over chop rather than piercing through it.

Because the RS Cat 16 relies on its hull shape for lateral resistance rather than retractable boards, it tracks well upwind for a rotomoulded boat, though it cannot point as high as a high-performance carbon or fiberglass racing cat. The boat feels stiff and responsive due to a unique beam-to-hull attachment system that minimizes the "racking" or twisting often found in older bolted-together multihulls. This structural rigidity ensures that the tension in the forestay and the shroud remains consistent, translating into more efficient sail shape and better speed in light airs.

The RS Cat 16 has gained significant traction within the global sailing school network due to its modular design and durability. It was notably highlighted by Yachting World during its initial launch as a "concise solution" for families and clubs looking for a catamaran that could be assembled and disassembled quickly without tools. While it has not been a primary "star" of major cinematic productions, it is a staple in high-end holiday resorts like Mark Warner and Sunsail, where it has become the benchmark for "beach-fleet" multihulls. The boat is also a frequent subject of technical walkthroughs by the RS Sailing YouTube Channel, which details the rig's versatility for single-handed or multi-crew use.

Known Issues & Buyer’s Checklist

While the RS Cat 16 is lauded for its ruggedness, prospective buyers and fleet managers should focus on several high-signal areas during inspection:

  1. Trampoline Tensioning: The trampoline is integrated into the hulls via a track system. Over time, the lacing or the material can stretch, leading to a "saggy" platform that slows the boat down and makes moving across the deck difficult. Check the underside of the trampoline for any signs of UV degradation or fraying at the eyelets.
  2. Rudder Kick-up Mechanism: The RS rudder system is designed to kick up automatically upon impact. However, sand and salt crystallization can jam the internal springs or the locking cams. Ensure the blades lock down firmly and release with a moderate amount of upward pressure.
  3. Beam Bolts and Fittings: While the "tool-free" assembly is a selling point, boats that are left assembled for long periods in salt environments can experience seizing in the beam-to-hull joints. Inspect the stainless steel hardware for signs of galvanic corrosion where it meets any aluminum components.
  4. Hull Weight: Rotomoulded PE3 is heavier than fiberglass. If a used boat feels exceptionally heavy, it may have water trapped inside the hulls. Check the drain plugs and inspection hatches to ensure the inner chambers are dry and the hull hasn't sustained a "breach" through the outer skin that has allowed the foam core to absorb moisture.

Community & Resources

The primary hub for owners is the RS Sailing Class Association, which provides support for both recreational users and those interested in the burgeoning catamaran racing scene. Technical support and replacement parts are managed through a global network of dealers, but the most comprehensive technical documentation is found via the RS Sailing Support Hub, which offers rigging guides and parts manuals for the Cat 16.

The Verdict

The RS Cat 16 is a triumph of utilitarian design, offering a "set it and forget it" ownership experience that is rare in the multihull world. It is an ideal platform for families who want to keep a boat on a beach or for clubs that require a vessel capable of withstanding the rigors of daily instruction.

Pros:

  • Extreme Durability: The Comptec PE3 hull can handle rough beaching and minor collisions that would crack a fiberglass boat.
  • Ease of Assembly: Can be broken down for transport or storage more easily than most cats in its class.
  • Stability: High-volume bows and a wide beam make it an exceptionally safe platform for teaching.

Cons:

  • Weight: Significantly heavier than fiberglass competitors, making it harder to move on a beach trolley by one person.
  • Performance Ceiling: While fast, it lacks the ultimate "twitchy" speed and upwind pointing ability of a daggerboard-equipped racing catamaran.
  • Aesthetics: The rotomoulded finish is functional but lacks the high-gloss "mirror" finish of a gelcoated vessel.
