Design Brief & Intent
The core design brief of the Young 6 was to deliver maximum on-the-water stability with minimal towing weight. To achieve this, Jim Young bypassed traditional, heavy cast-iron keels in favor of an innovative water ballast system. When empty on its trailer, the boat has a dry displacement of just 1,153 pounds, allowing it to be towed easily by compact passenger vehicles without requiring heavy-duty trucks. Once launched, the ballast tanks are flooded, adding substantial weight low in the hull to provide a stiff, stable platform capable of handling challenging coastal conditions.
This model was designed primarily for family weekend cruising and club racing in places like New Zealand’s Marlborough Sounds, lakes, and sheltered estuaries. However, its actual capabilities proved much broader over the decades. It has successfully competed in challenging coastal endurance events such as the Race to Alaska, where its dry bunks and surprisingly generous accommodations earned it a reputation as a highly seaworthy pocket voyager.
Compared to other popular trailer sailers of its era, such as the Farr 6000 or the Hartley 16, the Young 6 offered a unique blend of high performance and structural cleverness. The interior arrangement is surprisingly spacious for a hull under twenty feet. Its hard chine and flare provide a wide deck beam that translates into generous cabin and cockpit volume relative to its overall length. The cabin houses berths for up to four adults, a small slide-out galley space with provision for a stove and sink, and a dedicated spot for a chemical toilet 3. The warm timber joinery and straightforward layout emphasize utility, simplicity, and low-maintenance cruising.
Variations & Construction
While some database registries list the Young 6 as having a wing keel, this is a technical misnomer. The standard, authentic design utilizes a pivoting swing keel (or centerboard) housed in a central trunk, combined with a molded water ballast chamber in the bilge. This configuration allows the draft to range from a mere few inches with the board raised to over four and a half feet with the board fully lowered. The swing keel is ideal for beaching, shallow ramp launching, and exploring tidal estuaries, while providing excellent lift when sailing to windward.
In terms of construction, the vast majority of Young 6 yachts were built out of marine plywood, utilizing either a hard-chine plywood-over-stringer method or double-diagonal timber construction. Most are sheathed in Dynel or fiberglass epoxy (glass-over-plywood) for long-term durability. These were frequently sold as plans for home builders, though several were built professionally by New Zealand yards such as Nelson Boatbuilders. This plywood-and-epoxy construction yielded an incredibly light, rigid, and strong structure that is easy to repair and modify. While fiberglass composite versions of Jim Young’s larger designs became common in later decades, the Young 6 remains celebrated primarily as a masterclass in modern wooden boat building.
Sailing Performance & Handling
The Young 6 is a nimble and rewarding boat to sail. It features a fractional sloop rig, which keeps the headsails smaller and easily manageable for short-handed crews. The fractional configuration allows for precise mainsail control and mast bend, enabling owners to depower the boat easily in a blow.
With an exceptionally high dry sail area-to-displacement ratio of 33.32, the Young 6 is extremely responsive in light air. Under sail, it behaves more like a lively dinghy, accelerating quickly in gusts and showing excellent responsiveness at the helm. However, this light weight means that proper ballast management is absolutely critical. The boat has a high ballast-to-displacement ratio of 60.8% when the water ballast tank is fully flooded, which provides a powerful righting moment.
Its capsize screening ratio of 3.08 indicates that while it is highly stable for a light trailer sailer, it is not an offshore passage-maker and is vulnerable to rolling in extreme breaking seas if not handled correctly. In flat or moderate chop, the hard chine aft acts as a powerful stability reserve; as the boat heels, the chine digs in, widening the waterline and resisting further heel. Downwind, the boat is exceptionally fast and stable, particularly when carrying a spinnaker or gennaker, and has been known to outrun significantly larger keelboats in club races.
Technical Systems & Ballast Triage
The defining technical system of the Young 6 is its water ballast tank, and understanding its operation is essential for safe ownership. The ballast tank runs along the bottom of the hull and is filled by opening a sea-cock or unscrewing a brass bung located near the centerboard trunk while the boat is in the water. To empty the tank, owners historically had to unscrew the bung and tow the boat onto the trailer, letting gravity drain the water, or use manual bilge pumps.
A common modernization among current owners is the installation of 12-volt high-volume pumps or air-displacement systems to evacuate the water before hauling the boat out. Because the ballast tank is integral to the wooden hull structure, checking for soft spots, wood rot, or delamination inside the tank is a vital triage routine. If water is allowed to sit in a plywood ballast tank without a proper epoxy barrier coat, freshwater or saltwater rot can quickly compromise the keel trunk and surrounding floor frames.
The swing keel lift cable, turning blocks, and pivot pin also require periodic inspection. Because the keel is housed in a trunk that acts as a structural backbone, any play or wear in the pivot pin can cause clanking at anchor and wear away the fiberglass sleeve, leading to leaks. Keeping the centerboard trunk clean of marine growth is also necessary, as weed accumulation can jam the board in its housing.
The Verdict
The Young 6 is a brilliant example of New Zealand naval architecture that punches far above its weight class. By utilizing a water ballast system and a highly efficient hull shape, Jim Young managed to design a boat that is incredibly easy to tow, simple to launch, and highly stable once on the water. It offers a rare combination of dinghy-like responsiveness and genuinely usable weekend accommodations. While the maintenance demands of a plywood hull require a diligent owner, the reward is a classic, high-performance trailer sailer that delivers immense bang for the buck.
Pros:
- Extremely lightweight dry displacement makes it easy to tow with standard passenger vehicles.
- High ballast-to-displacement ratio provides excellent stability and safety when the tanks are flooded.
- Spaciously designed cabin and cockpit offer accommodations that rival much larger boats.
- High sail area-to-displacement ratio delivers exceptional light-wind performance and responsiveness.
- Swing keel and shallow draft allow for easy beaching, ramp launching, and shallow-water exploration.
Cons:
- Plywood-and-epoxy construction requires regular inspection and maintenance to prevent wood rot.
- Ballast tank must be thoroughly drained and dried to prevent internal wood deterioration and mold.
- Capsize screening profile restricts the vessel to coastal, lake, and sheltered water cruising rather than blue-water offshore work.
- Standard water ballast filling and draining procedures can be cumbersome without modernized pump upgrades.
