Name: Kaiulani 34
Brand: Kaiulani

Sailing Performance & Handling

The Kaiulani 34 is a "heavy cruiser" by design, characterized by a Displacement/Length (D/L) ratio of 327. This substantial mass, combined with a Motion Comfort Ratio of approximately 32.7, translates to a predictable and sea-kindly motion that minimizes fatigue during long offshore passages. Under sail, the boat utilizes a versatile cutter rig with a self-tending staysail on a club, allowing for easy sail reduction as the wind builds. According to Ted Brewer Yacht Design, the tall rig provides a Sail Area/Displacement (SA/Disp) ratio of 16.5, which ensures the vessel remains surprisingly agile in light-to-moderate airs despite its 15,500-pound displacement.

A defining characteristic of the underwater profile is the "Brewer Bite"—a distinct cutout in the trailing edge of the full keel just forward of the rudder. This modification reduces wetted surface area and significantly improves maneuverability in tight quarters compared to traditional full-keel designs, without sacrificing the directional stability or the protection of the propeller and rudder for which Brewer's designs are famous.

Interior Comfort & Variations

For a vessel of its size, the interior of the Kaiulani 34 is exceptionally well-appointed for live-aboard use. The layout typically features a V-berth forward, supplemented by a sea-going pilot berth and two settee berths in the main salon, allowing for comfortable sleeping arrangements even when the vessel is at a steep heel. The U-shaped galley is designed for security at sea, providing the cook with ample bracing points and deep storage lockers essential for long-range provisioning.

Perhaps the most notable interior feature is the head, which includes a separate stall shower—a luxury rarely found on 34-foot yachts. The joinery is generally of the highest caliber, often executed in cherry or teak, reflecting the semi-custom nature of the build. Because these boats were often built to specific owner requirements, variations exist; some hulls were delivered as "hull and deck" kits for owner finishing, though the core structural layout remains consistent across the fleet.

Popular Mentions & Media

While the Kaiulani 34 is a rare find on the brokerage market, it has earned a permanent place in the canon of serious cruising vessels. Long-distance voyaging expert John Neal of Mahina Expeditions lists the Kaiulani 34 and 38 as "Boats to Consider for Ocean Cruising," specifically praising their build quality and "lovely" lines. The model's reputation is built on the success of its larger sibling, the Kaiulani 38, which has several documented circumnavigations to its credit.

Known Issues & Buyer’s Checklist

Prospective buyers of a Kaiulani 34 must prioritize a specialized metal-hull survey. While aluminum is nearly immortal if cared for, it is susceptible to specific technical failure points:

Electrolysis & Galvanic Corrosion: Owners must verify the integrity of the electrical system’s isolation. Any stray current or lack of proper sacrificial anodes can lead to rapid pitting of the hull.
Paint Adhesion: Aluminum requires an exacting priming and painting process. Bubbling or "lifting" paint near the waterline or deck hardware often indicates moisture ingress or poor initial preparation.
Insulation Integrity: To prevent condensation and maximize comfort in extreme latitudes, these boats are typically insulated. Inspectors should check behind cabinetry for signs of "sweating" or mold that might occur if the insulation has gaps.
Tankage: Integrated aluminum tanks are a strength, but they must be inspected for internal corrosion if water or fuel has been sitting for extended periods.

Technical support for the Kaiulani 34 remains available through the archive of the designer. The Ted Brewer Yacht Design website continues to offer study plans and technical specifications for the design (Design #181), providing a valuable resource for owners conducting major refits or structural repairs.
