Blazer 740 Information, Review, Specs

Sailing Performance & Handling

The Blazer 740 is defined by its high power-to-weight ratio and a hull form optimized for early planing. With a light displacement and a generous sail plan, the boat is exceptionally responsive in light airs, often moving when heavier production cruisers remain stationary. According to technical assessments of the era, the 740 utilizes a deep, retractable bulb keel which provides the necessary righting moment to carry its large rig while maintaining the versatility of a trailerable vessel.

On the water, the 740 is known for its "dinghy-like" handling. It tracks well but requires active trimming and weight distribution to maximize performance. Downwind, the boat transforms when the spinnaker—typically a large symmetrical or asymmetrical setup on a retractable pole—is deployed, allowing the hull to break free of its bow wave and plane in moderate breezes. Owners often report that the boat feels balanced on the helm, though like many sportboats of its generation, it can be sensitive to over-pressing in heavy gusts. The cockpit layout is unashably racer-centric, featuring wide side decks for hiking and clear sightlines for the helmsman.

Interior Comfort & Variations

Despite its primary mission as a racer, the Blazer 740 features a surprisingly functional, albeit spartan, interior. The cabin provides enough volume for four adults to sleep in a basic configuration, typically consisting of a V-berth forward and two quarter berths extending under the cockpit. Headroom is limited, as is common in the "low-profile" sportboat category, necessitating a crouched posture when moving below deck.

The interior materials are focused on weight savings, often utilizing molded fiberglass liners and simple timber trim. Some variants were delivered with a basic galley module featuring a single-burner stove and a small sink, though many owners opted to keep the interior clear of amenities to reduce racing weight. The Blazer 740 shares its DNA closely with the Blazer 23; while the 740 generally refers to the metric measurement of its length (7.4 meters), the 23-foot designation was frequently used interchangeably in early marketing, with the 740 often featuring updated deck moldings or refined keel geometries.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a Blazer 740 with a focus on structural integrity, as these boats were often campaigned hard in competitive fleets.

• Keel Box and Pivot: As a lift-keel boat, the integrity of the keel trunk and the lifting mechanism is paramount. Inspect the area for stress fractures or signs of "wobble" that indicate worn bushings or structural fatigue in the trunk.
• Deck Core Integrity: Many Blazers were constructed using balsa or foam cores to save weight. Use a plastic hammer to check for "dead" thuds around high-load areas like chainplates, winches, and the mast step, which may indicate delamination or water ingress.
• Rigging and Spars: Given the age of the fleet, the standing rigging should be carefully scrutinized. Check the mast step for compression and the spreaders for signs of corrosion or metal fatigue, especially if the boat has been used in saltwater environments.
• Rudder Bearings: The high speeds achieved by the 740 put significant stress on the transom-hung or cassette-style rudders. Check for excessive play in the bearings or pintles, which can lead to vibration at high speeds.

Community & Resources

The primary hub for Blazer 740 owners and enthusiasts is the Australian Sport Boat Association (ASBA). This organization maintains the handicap ratings and class rules that governed the Blazer during its competitive peak and continues to provide a framework for sportboat racing where the Blazer 740 remains a competitive entry in various divisions. Technical discussions and tuning guides are occasionally archived within the regional sailing clubs of New South Wales and Queensland, where the class enjoyed its highest density of ownership.

The Verdict

The Blazer 740 is a purist’s sportboat that offers an accessible entry point into high-performance sailing without the complexity of modern carbon-fiber machines.

Pros:

• Exceptional light-air performance and planing potential downwind.
• Easily trailerable, allowing for low-cost storage and participation in away-regattas.
• Active racing heritage ensures a wealth of knowledge regarding sail trim and tuning.

Cons:

• Interior comfort is minimal and unsuitable for extended cruising.
• The lightweight construction requires diligent maintenance to prevent structural degradation.
• Can be physically demanding to sail at its limit compared to more stable, heavy-ballast keelboats.
