The Wyliecat 17 represents a radical departure from traditional small-boat architecture, blending the ease of a dinghy with the sophisticated engineering of a high-performance racing yacht. Designed by the renowned Tom Wylie and built by the legendary Moore Sailboats in Watsonville, California, the 17 is the smallest entry in a lineage of vessels that prioritize simplicity and speed. Unlike conventional sloops, the Wyliecat 17 utilizes a single, massive mainsail set on a freestanding carbon fiber mast, eliminating the need for shrouds, stays, or a jib. This "keep it simple" philosophy results in a boat that can be rigged and launched in minutes, yet possesses the hull speed and responsiveness to challenge much larger designs. The partnership between Tom Wylie and Ron Moore ensured that the 17 benefited from the same ultralight displacement (ULDB) expertise that made the Moore 24 a sailing icon, resulting in a stiff, lightweight hull capable of exceptional performance.

Sailing Performance & Handling
The performance of the Wyliecat 17 is defined by its unstayed carbon fiber rig, which allows the mast to flex and automatically "bend off" the top of the sail in heavy gusts. This feature, detailed in Wyliecat's technical specifications, provides a built-in safety valve, making the boat surprisingly manageable for a single-handed sailor despite its generous sail area. The use of a wishbone boom ensures that the sail maintains an optimal aerodynamic profile across all points of sail without the need for complex vang systems or traveler adjustments.
Handling is described as exceptionally light and "dinghy-like" in its responsiveness. Because it lacks a jib, tacking is instantaneous—the sailor simply puts the tiller over, and the boat follows without the need to winch or trim sheets. On a reach or a run, the Wyliecat 17's flat aft sections and lightweight construction allow it to plane early. While technical ratios for a 17-footer are rarely the focus of cruising guides, the high sail-area-to-displacement ratio provided by the carbon mast's weight savings allows the boat to maintain momentum in light air that would leave heavier boats becalmed.
Sibling Models
While the 17 is the most compact of the Wyliecat family, it shares its DNA with several larger high-performance siblings. The most famous is the Wyliecat 30, a boat that gained legendary status on San Francisco Bay for its ability to outpace 40-foot sloops upwind while being handled by a crew of only one or two. Other siblings built on the same cat-rigged philosophy include the Wyliecat 39, 44, and 48. Whereas the larger models include accommodations for coastal racing and cruising, the 17 remains a pure daysailer, focused entirely on the ergonomics of the cockpit and ease of transport.
Popular Mentions & Media
The Wyliecat 17 has maintained a dedicated following within the West Coast sailing community. It has been frequently featured in Latitude 38, California's premier sailing magazine, particularly in coverage of "Small Boat" regattas and single-handed racing events. Its designer, Tom Wylie, is often cited in naval architecture discussions for his commitment to the "Wyliecat" concept, which challenges the inherent complexity of the modern fractional sloop rig. The boat is often seen as the "connoisseur’s dinghy," appealing to experienced sailors who want high performance without the physical toll of managing complex rigging.
Known Issues & Buyer’s Checklist
Prospective buyers of a used Wyliecat 17 should focus their inspection on the specialized components that define the model:
- Mast Partners and Step: Because the mast is unstayed, all the leverage of the sail is transferred directly to the deck partners and the mast step. Inspect these areas for stress cracking or crazing in the gelcoat, which may indicate structural fatigue.
- Wishbone Boom Integrity: The wishbone boom is a critical component. Inspect the "choke" (where the boom attaches to the mast) and the aft clew attachment for wear or corrosion.
- Carbon Fiber Condition: While carbon fiber is incredibly strong, older masts should be checked for UV degradation or deep scratches that could compromise the laminate.
- Rudder Bearings: The high sail area of a cat-rig can put significant load on the rudder. Check for "slop" or play in the rudder head and pintles, as this can dull the boat's signature precise handling.
Community & Resources
The primary resource for technical data and factory support remains the official Wyliecat website. While there is no large-scale "one-design" class for the 17 compared to the Wyliecat 30, owners are often integrated into the broader Wyliecat Association. This community is known for being highly technical and supportive, often sharing rigging tips for optimizing the freestanding cat-rig.
The Verdict
The Wyliecat 17 is an uncompromising performance daysailer that offers the thrills of a racing boat with the simplicity of a Sunfish.
Pros:
- Ease of Use: Can be rigged and sailing in under 10 minutes.
- High Performance: Exceptional speed-to-length ratio and early planing.
- Build Quality: Constructed by Moore Sailboats, ensuring a robust yet lightweight hull.
- Safety: The flexible carbon mast automatically depowers the boat in heavy air.
Cons:
- Specialized Rig: Replacement parts for the carbon mast or wishbone boom can be expensive and difficult to source.
- Limited Utility: No interior or storage space makes it strictly a fair-weather daysailer.
- Niche Market: Can be harder to find on the used market than more common dinghies.
