G-Cat 5.7 Information, Review, Specs

As a product of G-Cat Multihulls, a company that built over 2,000 units, the 5.7 reflects a commitment to accessible and enjoyable multihull sailing. Its design prioritized user-friendliness and safety, making it a popular choice for both competitive racing and relaxed recreational sailing.

History and Design

The G-Cat 5.7 emerged as a significant model in G-Cat Multihulls' lineup, following the success of the G-Cat 5.0, which debuted in 1975. Designed personally by Hans Geissler, the 5.7 first entered production in 1980, conceived primarily as a one-design racer. Geissler's overarching goal for his designs was to create "fun family boats" that were also noted for being fast and easy to sail.

A hallmark of the G-Cat 5.7's design philosophy was its innovative boomless main, a safety feature that significantly reduced the risk of head injuries during maneuvers compared to traditional rigs. The boat also featured "high volume hulls" and a "boardless design," contributing to its ease of handling and performance, characteristic of G-Cat's identity, 5]. Furthermore, the integration of a front trampoline not only enhanced the boat's comfort but also provided additional lounging space, distinguishing it from other beach catamarans of the era. While specific variations like a "rental mast and sail configuration" existed, the core design remained consistent with Geissler's vision for a versatile and approachable multihull.

Sailing Performance and Handling

With a lightweight displacement of just 360 pounds and a length overall of 18.67 feet, the G-Cat 5.7 is a nimble and responsive multihull. Its hull type is described as a "Catamaran (no boards/asym)" with a fractional sloop rigging and a rotating spar, indicating a design focused on performance and efficiency. This configuration, combined with its high-volume hulls, contributes to its reputation for being both fast and relaxed to sail 3, 8, Builder Article.

Owners and enthusiasts often describe the G-Cat 5.7 as a "fun boat" with "big buoyant looking hulls". While it excels in a variety of conditions, some sources suggest that sailing directly downwind may require a gennaker or spinnaker for optimal speed. Its inherent stability and ease of handling make it suitable for both experienced sailors looking for a spirited ride and newcomers to multihull sailing.

Accommodations and Layout

As an open-deck beach catamaran, the G-Cat 5.7's "accommodations" are focused on its deck layout for sailing and relaxation rather than enclosed living spaces. A key feature, and a distinguishing characteristic, is the presence of a "front trampoline," offering significant lounging space and contributing to the boat's comfort. In addition to the forward area, an "aft trampoline" is also available, further enhancing the functional deck space.

The "high volume hulls" provide inherent buoyancy, but interior storage is typically minimal and often relies on portable bags or dry containers for gear. The design prioritizes open-air enjoyment and ease of movement on deck, aligning with its purpose as a recreational and racing beach catamaran.

Owner's Perspectives

Owners frequently commend the G-Cat 5.7 for its enjoyable and "relaxed" sailing experience, often citing its speed and suitability for "adventure sailing" and introducing new individuals to the sport. The buoyant hulls are a well-regarded feature, contributing to the boat's stable feel on the water. The innovative boomless design is also a significant plus for many owners, enhancing safety by eliminating the risk of head injuries during maneuvers.

However, common maintenance considerations for older G-Cat 5.7s include the potential for "soft spots on decks," particularly behind the front crossbeam and in areas where the mainsheet block is attached. As with many older fiberglass boats, gel coat chips and cosmetic issues are also frequently observed. Owners also note that sourcing parts for classic G-Cat models can be challenging due to the cessation of large-scale production, necessitating a dedicated owner community for knowledge sharing and parts acquisition.
