Sunbird 25 MS Information, Review, Specs

Sailing Performance & Handling

The Sunbird 25 MS is characterized by a "sedate pace" under sail, largely due to its modified rig and hull configuration. According to technical documentation from the Sunmaid Association of Victoria, the MS version typically features a smaller mainsail (approximately 130 square feet) to accommodate a higher boom and the prominent "doghouse" or wheelhouse. The boat’s performance is heavily influenced by its displacement-to-ballast ratio of approximately 35%, providing a stiff and stable platform that feels secure in coastal choppy waters.

Unlike the swing-keel TS version, the original MS often utilized a long, shallow ballast keel with a three-bladed propeller housed in an aperture between the keel and the skeg-mounted rudder. This setup significantly improves tracking under power but introduces more drag when sailing. Handling is generally predictable, though contemporary tests noted that the narrow rudder profile could lead to stalling in heavy gusts if the boat was allowed to round up. Most owners find the self-tacking jib a practical addition, simplifying single-handed operations in the cockpit while sacrificing some light-air pointing ability.

Interior Comfort & Variations

The defining feature of the Sunbird 25 MS is its enclosed doghouse, which provides a level of protection rarely found in 25-footers. This structure houses the secondary internal steering station and instrumentation, allowing the skipper to navigate in inclement weather. The interior layout is surprisingly spacious for its length, offering approximately 5' 10" of headroom in the main cabin and upwards of 6' 4" under the doghouse.

Accommodation is typically configured for four to six people, though it is most comfortable for a couple or a small family. The V-berth forward is enclosed for privacy, while the main saloon features a dinette that converts into a double berth. A notable variation in the MS model is the galley placement; in many units, the galley is moved aft toward the cockpit area under the shelter of the wheelhouse to maximize interior lounging space. The use of a full internal GRP liner makes the cabin easy to maintain, while timber trim and carpeting were standard to provide a warmer aesthetic.

Popular Mentions & Media

While the Sunbird 25 MS does not have a high-profile Hollywood footprint, it maintains a significant cultural legacy within the Australian "trailerable" community. It was a centerpiece of the Melbourne and Sydney boat shows in the late 1970s, often described as a "gamble" that paid off for the manufacturer due to the instant demand for a comfortable, small-scale motor sailer. The boat's development and early sea trials were documented in period Australian sailing journals, which are preserved in the archives of John Crawford Marine, highlighting its reputation as the "step-up" boat for families graduating from smaller 20-foot day-boats.

Known Issues & Buyer’s Checklist

Potential buyers should focus their inspections on the unique structural elements of the MS variant.

• Window Seals: The large windows of the doghouse are prone to leaking over time. Inspect the interior lining for water stains or "milky" GRP, which indicates long-term moisture ingress.
• Rudder and Skeg: Unlike the transom-mounted rudder of the TS model, the MS rudder is mounted on a skeg. Check the pintles and gudgeons for play, as the narrow blade design puts significant stress on the hardware in heavy weather.
• Deck Core: The deck is constructed using a foam and timber sandwich GRP. Buyers should walk the side decks specifically near the chainplates and doghouse joints to check for "soft spots" or delamination.
• Engine Maintenance: Because the MS relies heavily on its auxiliary power (often a Volvo Penta or Bukh diesel), the engine mounts and exhaust elbow should be checked for corrosion. Many older units may still have the original 7.5hp to 15hp engines, which may be nearing the end of their service life.

Community & Resources

The primary hub for technical support and class history is the Sunmaid & Sunbird Association, which provides access to original design rules, sail plans, and maintenance tips. The association is particularly active in Victoria, Australia, where many of these vessels were built and continue to be raced and cruised in the Gippsland Lakes.

The Verdict

The Sunbird 25 MS is an excellent choice for sailors who prioritize comfort and "all-weather" capability over speed. Its robust construction and protected helm make it a standout in the vintage 25-foot market.

Pros:

• Enclosed wheelhouse provides excellent weather protection.
• High interior volume and standing headroom for a 25-foot boat.
• Stable and forgiving handling characteristics.
• Strong community support through dedicated owner associations.

Cons:

• Reduced sailing performance compared to the Sunbird 25 TS.
• Potential for rudder stall in high-wind conditions.
• Complex window and deck joint maintenance.
• Heavier weight makes frequent trailering more demanding.
