Design Brief & Intent
The core mission of the Clever 23 was to maximize interior volume, ease of transport, and shallow-water utility without requiring a heavy-duty tow vehicle. To achieve this, Skrzat penned a hull with a generous beam of 8.2 feet on a modest waterline length. This wide beam-to-length ratio yielded an incredibly spacious cockpit and accommodation plan for a boat under 24 feet.
Step down the companionway, and the boat's interior layout defies its trailerable dimensions. The cabin features a bright, open-plan arrangement made possible by a molded fiberglass headliner and light-colored gelcoat surfaces, accented by basic wood trim to prevent a clinical feel. Sleeping arrangements comfortably accommodate four adults, split between a V-berth in the bow and a surprisingly large double berth tucked transversely beneath the cockpit sole. A small, functional galley sits to port of the keel trunk, equipped with a two-burner gas stove, a sink fed by a manual freshwater pump, and dedicated storage for a coolbox. To starboard of the keel trunk, a clear passage leads forward, while space under the companionway steps is specifically engineered to house a chemical toilet. While the joinery and finish quality reflect the boat's budget-conscious, production-line origins, the structural fit-out is highly pragmatic, prioritizing easy-to-clean surfaces and maximum storage lockers beneath the settees.
Variations & Configurations
While the Clever 23 was predominantly produced in a single hull shape, owners could select from functional rigging and keel variations designed to suit distinct sailing environments. The standard configuration features a fractional 7/8 sloop rig with an aluminum mast, often paired with a tabernacle or "mast-cheetah" lowering system. This mast-raising gear is a hallmark of the model, allowing short-handed crews to step and strike the rig on the water when confronting low bridges on inland canal networks.
The primary structural variation lies in the keel design. While some rare fixed-shoal versions were built, the vast majority of Clever 23s utilize a lifting keel system. This consists of a cast-iron slab winging down to a maximum draft of 4.59 feet, which can be fully retracted into the hull's shallow keel stub to a scant draft of 0.92 feet. This variable draft fundamentally changes the boat's capabilities: with the keel retracted, it can be launched directly from a standard trailer ramp, navigate skinny inland waterways, and easily dry out flat on sandy moorings or tidal flats.
Sailing Performance & Handling
Under sail, the Clever 23 behaves like a spirited, oversized dinghy rather than a heavy keelboat. Boasting a high Sail Area to Displacement (SA/Disp) ratio of 22.67, the boat is remarkably lively in light-to-moderate air. It accelerates quickly out of tacks and glides effortlessly in light breezes that leave heavier cruisers becalmed. The light displacement-to-length (Disp/LWL) ratio of 126.38 points to an easily driven hull form that, under spinnaker in downwind conditions, is fully capable of breaking free of its theoretical hull speed and transitioning into a plane.
However, this lively performance demands active sheet handling as the wind builds. With a modest Ballast-to-Displacement ratio of 28.55% and a very low Comfort Ratio of 9.7, the Clever 23 is undeniably tender. The flat-bottomed, wide-beam hull shape provides initial form stability, but once the wind exceeds 12 to 15 knots, the boat heels rapidly and must be reefed early to maintain control. Upwind performance in a steep chop can be punishing; the relatively flat entry forward is prone to slamming, which quickly saps momentum. At the helm, the single transom-hung rudder provides excellent, tactile feedback in light air, but if the boat is allowed to heel excessively, the rudder can become heavily loaded or lose traction entirely, resulting in round-ups. Consequently, sailing the Clever 23 efficiently requires a crew that treats it with the trim-sensitive mindset of a racing dinghy.
Known Issues & Triage
The lifting keel is both the Clever 23's greatest asset and its primary source of mechanical vulnerability. The cast-iron keel is raised and lowered via an internal stainless steel wire cable routed through a series of pulleys to a cabin-top winch. Over time, this cable is highly susceptible to fraying and crevice corrosion inside the wet keel trunk. A snapped cable can cause the heavy keel to drop violently, risking structural damage to the fiberglass trunk or jamming the keel in the down position. Veteran owners on the Sportina Forum emphasize a mandatory preventative triage routine: inspecting the cable annually and replacing it every five years. Many owners now substitute the stainless steel wire with modern Dyneema line to eliminate corrosion issues.
Another systemic issue involves the tight tolerances within the keel trunk. Sand, mud, and organic debris can easily lodge in the narrow slot when drying out, occasionally jamming the keel in the raised position. Additionally, as the internal sacrificial guides or shims wear down over years of service, the keel can develop lateral play, leading to an annoying "clanking" sound when sailing in a seaway or resting at anchor.
The transom-hung rudder assembly is also prone to wear. Because the rudder blade is designed to kick up in shallow water, the pivot bolt and aluminum casting can develop significant play, which degrades helm sensitivity and introduces vibration. Regular inspection of the rudder gudgeons, pintles, and the kick-up locking mechanism is required to ensure structural integrity under load.
Modernization & Upgrades
Many current owners are actively modernizing the Clever 23 to capitalize on its excellent trailer-sailer characteristics. One of the most common and practical upgrades is the transition to electric outboard propulsion. Because the vessel is so light, a 2 kW to 4 kW electric pod or outboard motor provides ample power for maneuvering in and out of marinas, completely eliminating the weight, smell, and maintenance of a traditional 8-horsepower four-stroke gasoline outboard.
To support electric propulsion and general house loads, owners frequently replace the original lead-acid battery banks with lightweight Lithium Iron Phosphate (LiFePO4) batteries. This weight savings is crucial for a boat designed to be trailered behind standard family cars. On the rig, retrofitting a modern "maindrop" stackpack system with lazy jacks significantly simplifies single-handed mainsail dousing, while upgrading the original roller-reefing jib to a high-quality furler with a foam luff helps maintain acceptable sail shape when partially rolled in heavy air.
The Verdict
The Clever 23 remains a highly successful compromise for sailors seeking a spacious, trailerable pocket cruiser capable of shallow-water exploration. While it lacks the heavy-weather stiffness and tracking of a fixed-keel pocket cruiser, its clever layout, ease of launching, and energetic light-air performance make it an exceptionally fun boat for inland lakes, estuaries, and sheltered coastal cruising.
Pros
- Highly versatile lifting keel allows a minimum draft of under one foot, ideal for beaching, beach-crawling, and simple ramp launching.
- Outstanding interior volume and cockpit space for a 23-foot boat, easily accommodating a family of four for weekend trips.
- Extremely lively and responsive sailing characteristics in light-to-moderate wind conditions.
- Standard mast-lowering system simplifies canal navigation and eliminates the need for yard cranes.
Cons
- Highly tender hull design that requires early reefing and active mainsail trimming in winds above 12 knots.
- Flat forward hull sections lead to uncomfortable slamming when tackling a steep chop.
- Lifting keel cable, pulleys, and internal shims require regular, strict maintenance to prevent jamming or mechanical failure.
- Lightweight construction and low comfort ratio make it unsuitable for offshore or rough-water passages.
