The Young Sun 43 is a heavydisplacement cruising yacht that epitomizes the "Taiwanese doubleender" era of the late 1970s and 1980s. Emerging from the same regional industry that produced the more famous Hans Christian and Baba yachts, the Young Sun 43 was built to satisfy a specific market demand for rugged, bluewater vessels capable of comfortable longrange voyaging. While the builder, Young Sun Yacht Corp, is often associated with the Robert Perrydesigned 35, the 43 is a more substantial platform that closely mirrors the lines of the Hans Christian 43, leading to historical debates regarding design provenance and yard "mold sharing" common in Taiwan during that period.

Sailing Performance & Handling

The Young Sun 43 is a quintessential heavy-weather vessel, defined by its full keel and significant displacement. With a high Displacement to Length (D/L) ratio, the hull is designed more for momentum and sea-kindliness than for light-air agility. It excels in a "blow," where its mass and deep forefoot allow it to power through chop that would stall lighter coastal cruisers. The boat’s directional stability is exceptional, a direct result of the long keel and substantial wetted surface, which allows the vessel to track well on long offshore passages with minimal input from a windvane or autopilot.

Typically rigged as a cutter, the 43 provides a versatile sail plan that allows for easy reefing and balanced handling in heavy air. Owners often report that the boat feels "stiff," meaning it resists heeling even when over-canvassed, providing a sense of security for the crew. However, this stability comes at the cost of light-air performance; in winds under 10 knots, the sheer weight of the hull and the friction of the large wetted surface make the boat sluggish. Handling under power requires experience, as the long keel makes backing up unpredictable, a characteristic common to the "canoe stern" designs of this lineage.

Interior Comfort & Variations

The interior of the Young Sun 43 is often referred to as a "teak cave," a term of endearment for the exhaustive use of solid tropical hardwoods, hand-carved joinery, and marble or granite accents typical of 1980s Taiwanese craftsmanship. The layout was frequently customized, but the most common configuration features a large Pullman berth forward or a V-berth, a cavernous U-shaped galley, and a dedicated navigation station that rivals those found on much larger ships.

Two primary variants of the 43 exist: the standard trunk cabin version and the Pilothouse (often referred to as the "Young Sun 43 Pilothouse"). The Pilothouse variant is particularly sought after by high-latitude cruisers, offering an internal steering station and panoramic windows that dramatically increase the natural light in the main salon. Regardless of the version, headroom is generous throughout, and the heavy build of the hull provides excellent thermal and acoustic insulation from the elements.

Known Issues & Buyer’s Checklist

Prospective buyers must approach the Young Sun 43 with a focus on the specific structural liabilities common to high-teak Taiwanese builds of this era.

  • Teak Deck Integrity: Like many of its contemporaries, the Young Sun 43 often featured teak decks screwed directly into a cored fiberglass sub-deck. Over decades, the bungs and sealant fail, allowing water to migrate into the core. Evidence of "spongy" decks or brown streaks in the interior overhead is a major red flag indicating potential core rot.
  • Black Iron Fuel Tanks: The original fuel tanks were often constructed of black iron, which is prone to internal corrosion and eventual leaking. Because the boat was built around these tanks, replacement is a major undertaking that often requires cutting into the cabin sole or dismantling interior furniture.
  • Chainplate Corrosion: The stainless steel chainplates are often glassed in or hidden behind heavy teak cabinetry, making inspection difficult. Crevice corrosion in these areas is a common "gotcha" that can lead to rig failure if not addressed.
  • Portholes and Hawse Pipes: The cast bronze fittings are beautiful but prone to leaking if the original bedding compound has dried out. Persistent leaks around the "butterfly" hatches or bronze ports can lead to localized wood rot in the interior joinery.

Community & Resources

While there is no longer a formal factory presence, the Young Sun 43 is often supported by the broader community of "Taiwanese double-ender" enthusiasts. Technical data and restoration advice are frequently shared within the Robert Perry Fan Club (a group dedicated to the designer’s various works, including the unauthorized "sister" designs) and the Hans Christian Owners Association, given the significant overlap in construction techniques and hardware.

The Verdict

The Young Sun 43 is a "tank" of a sailboat, offering a level of security and aesthetic charm that modern, mass-produced fiberglass boats rarely achieve. It is a specialist’s vessel, best suited for a couple or small crew planning to live aboard and cross oceans.

Pros

  • Exceptional Seaworthiness: A heavy-displacement hull that provides a stable, safe motion in blue-water conditions.
  • Exquisite Craftsmanship: The level of interior woodworking and bronze hardware is nearly impossible to replicate at modern price points.
  • Tracking and Stability: The full keel design allows for effortless tracking and excellent heavy-weather performance.

Cons

  • High Maintenance: Extensive exterior teak and aging systems require a significant commitment of time and money.
  • Poor Light-Air Agility: The vessel’s weight and wetted surface make it slow and cumbersome in light winds.
  • Difficult Maneuverability: The full keel and propeller aperture make docking in tight marinas a challenge for the uninitiated.
