The Aloha 34, also known in international markets as the Aloha 10.4, represents the pinnacle of the collaboration between the Canadian builder Ouyang Boat Works and the renowned design partnership of Ted Brewer and Robert Walstrom. Launched in 1975, the vessel was conceived during an era when the fiberglass production market was shifting from narrow, traditional hulls to the beamier, more voluminous shapes that define modern cruising. The 34 was the flagship of the Aloha line for several years, positioned as a robust offshore-capable coastal cruiser that prioritized comfort and structural integrity over raw racing speed. Built in Whitby, Ontario, the boat became a staple of Great Lakes sailing but eventually found its way to salt water, where its heavy-displacement characteristics and lead ballast proved well-suited for more demanding conditions.

Sailing Performance & Handling
Under sail, the Aloha 34 is often described as a "gentleman’s cruiser," favoring predictability and a soft motion over aggressive acceleration. With a displacement-to-length ratio hovering around 250, it sits firmly in the medium-heavy category, which provides a high degree of sea-kindliness in a chop. The hull features a moderate fin keel and a skeg-mung rudder, a configuration favored by Ted Brewer for its balance of maneuverability and directional stability. According to design insights from the Ted Brewer Yacht Design archives, his boats often utilized a "Brewer Bite" (a modification to the skeg) to improve water flow to the rudder, though the 34 remains a more traditional execution of his cruising philosophy.
The sail area-to-displacement ratio of approximately 15.5 indicates that the boat requires a decent breeze—typically 10 knots or more—to truly wake up. In light air, the heavy wetted surface area can make the vessel feel sluggish compared to modern performance cruisers. However, as the wind freshens, the Aloha 34 shines. It carries its canvas well and is notably stiff, thanks to a ballast ratio of nearly 40%. Owners often report that the boat tracks exceptionally well on a reach, requiring little effort at the helm once the sails are properly trimmed.
Interior Comfort & Variations
The interior of the Aloha 34 was one of its primary selling points in the late 1970s, offering a level of volume and joinery work that rivaled more expensive European imports. The layout is a classic offshore arrangement: a forward V-berth, a head with a shower to port, and a main salon featuring a U-shaped dinette that can convert into a double berth. Ouyang Boat Works was known for its "personal touches," which manifested in the 34 through extensive use of Burmese teak and high-quality cabinetry.
Unlike its smaller sibling, the Aloha 28, the 34 provided true standing headroom of roughly 6'4", making it a viable live-aboard for taller sailors. A notable variation in the model line involves the engine evolution; while early units were sometimes fitted with the gas-powered Atomic 4, the vast majority were delivered with reliable Universal or Westerbeke diesel engines. The galley is typically located to starboard at the base of the companionway, featuring a deep sink and an icebox (often converted to refrigeration in the secondary market) that is designed to be functional even while the boat is heeled.
Known Issues & Buyer’s Checklist
Prospective buyers should approach an Aloha 34 with a focus on its age-related structural health. While the hulls are solid fiberglass, the decks utilize a balsa core which is prone to saturation if deck hardware has not been periodically re-bedded.
- Deck Delamination: Use a phenolic hammer to tap for "dead" spots around the stanchion bases and the windlass area. Soft spots are common in boats that have spent decades in freeze-thaw cycles.
- Chainplates: The stainless steel chainplates are robust but can develop crevice corrosion where they pass through the deck. Inspection of the knees and the surrounding glass work in the salon is critical.
- Rudder Post Sealing: Some owners have reported leaks around the rudder post stuffing box, which can be difficult to access and service due to the cockpit layout.
- Fuel Tank Material: Like many boats of this era, the original aluminum fuel tanks may be reaching the end of their lifespan due to internal corrosion from ethanol-blended fuels or condensation.
Community & Resources
The Aloha 34 benefits from a highly organized and technically proficient owner base. The Aloha Owners Association serves as the primary repository for original brochures, wiring diagrams, and specific maintenance wikis for the 34 and its siblings. This community is particularly active in the Pacific Northwest and the Great Lakes, where many of these vessels are still actively campaigned in club races and regional cruises.
The Verdict
The Aloha 34 remains one of the most respected Canadian-built cruisers of its generation. It is a "honest" boat that does not pretend to be a racing yacht, offering instead a safe, sturdy, and aesthetically pleasing platform for long-distance coastal cruising.
Pros:
- High-quality interior joinery and significant living volume for its length.
- Predictable and stable handling in heavy weather.
- Solid fiberglass hull construction provides long-term durability.
- Strong support from a dedicated owners' association.
Cons:
- Underpowered in light wind conditions (less than 8 knots).
- Potential for significant deck core repair if neglected.
- Access to certain engine components can be tight for DIY mechanics.
