Ross 40 TM Information, Review, Specs

Sailing Performance & Handling

The Ross 40 TM is defined by a high power-to-weight ratio and a hull form that draws heavily from Murray Ross’s background in skiff design. Unlike the heavy-displacement cruisers of its era, the 40 TM features a relatively light displacement, which, when paired with a generous sail plan, allows it to transition into a plane under the right conditions—a rarity for a "touring" yacht of this size. The boat’s handling is frequently described by owners as "dinghy-like" in its responsiveness, requiring an active hand on the helm but rewarding the sailor with exceptional feedback.

Technical interpretations of its ratios suggest a vessel that excels in light-to-moderate air, where it can easily outpace contemporary production cruisers. However, its performance in heavy weather requires careful sail management; because the hull is relatively light, the boat can become lively in a following sea. The "TM" version typically features a slightly more conservative rig than the "R" (Racing) version, yet it still possesses a high Sail Area/Displacement ratio that necessitates early reefing to maintain an upright, efficient posture. According to historical design notes from Boating New Zealand, Murray Ross designs of this period focused on "minimum drag and maximum surfing potential," which translates to a boat that tracks exceptionally well off-the-wind but requires a high-aspect-ratio keel to maintain pointing ability.

Interior Comfort & Variations

The "Touring Model" designation specifically addresses the interior volume and amenities that were often stripped back in the racing 40s. The 40 TM typically features a three-cabin layout, though custom builds in New Zealand yards led to several variations. The use of native New Zealand timbers, such as Kauri or Teak, is common in these builds, providing a warm, high-quality aesthetic that contrasts with the boat’s modern, aggressive exterior lines.

The coachroof of the TM is slightly elevated compared to the racing version, providing better standing headroom (typically around 6'2") and larger windows for increased natural light. The galley is generally positioned to port, optimized for use at sea with deep sinks and secure bracing points. Sibling models include the Ross 40 "R" (Racing), which features a minimalist interior and a deeper, more specialized keel, and the Ross 12m, which shared many of the same design DNA but was often optimized for specific rating rules of the time. The 40 TM remains the most liveable of the variations, offering a genuine balance for a family that wants to cruise to a destination and then compete in a local regatta.

Known Issues & Buyer’s Checklist

Prospective buyers of a Ross 40 TM should focus on the structural integrity of the hull-to-deck joint and the keel floors, especially if the vessel has a history of offshore racing.

• Keel Attachment and Floors: Because the Ross 40 TM is a performance-oriented boat, the stresses on the keel floors can be significant. Inspect for any signs of "panting" or cracking in the fiberglass around the keel bolts, which may indicate a history of hard groundings or extreme racing stress.
• Deck Core Integrity: Many Ross designs utilized balsa or foam coring to save weight. Areas around stanchion bases, chainplates, and mast steps should be checked with a moisture meter for any signs of delamination or water ingress, which can compromise the deck's stiffness.
• Rudder Bearings: The high-aspect-ratio spade rudders on these boats are under high load. Check for excessive "play" or stiffness in the steering system, as bearing replacement on these custom New Zealand builds can sometimes require bespoke machining.
• Chainplate Leaks: Like many boats of this vintage, the chainplates are prone to minor leaks that, if left unaddressed, can cause aesthetic damage to the interior timber or, worse, structural degradation to the bulkhead attachments.

Community & Resources

The primary hub for Ross 40 owners and enthusiasts is the New Zealand maritime community. Technical discussions and historical data are often preserved by the Murray Ross Design archives. While there is no centralized international "class association" for the 40 TM specifically, the boat is a frequent topic within the Royal New Zealand Yacht Squadron and other Auckland-based sailing clubs, where many of these vessels were originally commissioned and raced.

The Verdict

The Ross 40 TM is a specialized vessel for the sailor who refuses to sacrifice speed for comfort. It is an "honest" performance cruiser that rewards skilled handling and offers a level of craftsmanship rarely found in mass-produced yachts.

Pros

• Exceptional Speed: Outperforms almost any traditional cruiser in its size class, particularly in light air.
• Build Quality: Most were built in reputable New Zealand yards with high-grade materials and native timbers.
• Dual-Purpose Capability: Equally at home on a summer cruise or a competitive offshore race circuit.

Cons

• Demanding Handling: Not a "set-and-forget" cruiser; requires active sail trimming and attention to the helm.
• Age-Related Maintenance: Cored decks and performance rigs from the late 80s/early 90s require diligent upkeep.
• Niche Market: Their performance pedigree means they are often "sailed hard," requiring a thorough survey to find a well-preserved example.
