Ferretti Altura 424 Information, Review, Specs

Sailing Performance & Handling

The Altura 424 is a quintessential motorsailer, designed with a hull form that favors stability and comfort in a seaway rather than light-wind agility. With a relatively high displacement-to-length ratio, the boat carries its momentum well through chop, providing a dry and predictable ride. Most 424s were rigged as ketches, a configuration that allows for a versatile "sail plan for all seasons," enabling owners to balance the boat easily by dropping the mainsail and sailing under "jib and jigger" (mizzen and genoa) when the wind picks up.

The steering is typically hydraulic, which, while reducing the tactile "feel" of the rudder compared to cable steering, makes for effortless handling during long passages under power or sail. According to historical technical assessments from Italian nautical circles, the boat performs most efficiently when the large diesel engine—often a Perkins or Mercedes-Benz marinized unit—is used to assist the sails in light air. Its tracking is exceptional thanks to a long-fin keel and a protected skeg-hung rudder, making it a "hands-off" cruiser that does not require constant correction at the helm.

Interior Comfort & Variations

The interior of the Altura 424 is where Ferretti’s heritage in luxury craftsmanship is most evident. The layout is defined by its split-level arrangement; the raised saloon offers panoramic views through large wrap-around windows, a feature that was revolutionary for the early 1980s. The woodwork is typically high-gloss or satin teak, executed with a level of joinery that exceeds modern production standards.

The 424 generally features a three-cabin layout. The master stateroom is located aft, taking full advantage of the hull’s beam and offering a private sanctuary with an en-suite head. Sibling models like the Altura 422 shared this hull form but often differed in the galley arrangement or the height of the coachroof. In the 424, the galley is typically "linear" or "U-shaped," positioned lower than the saloon to maximize work space without encroaching on the social areas. Headroom is generous throughout, often exceeding 6'4" in the main saloon, making it one of the most liveable 42-footers of its generation.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the Ferretti Altura 424 with a focus on systems and structural longevity. While the hulls are robust, they are of an age where specific maintenance cycles are critical.

• Teak Deck Integration: Many 424s were delivered with thick teak decks screwed and glued over fiberglass. Over forty years, these screws can become conduits for moisture into the deck core. A thorough moisture meter test of the sub-deck is mandatory.
• Osmotic Blistering: Like many Mediterranean builds of the late 70s and early 80s, the Altura series is susceptible to osmosis. Evidence of hull stripping or epoxy treatment in the boat’s history is a significant value-add.
• Engine Serviceability: The engines are often located deep within a soundproofed compartment beneath the saloon floor. While quiet, accessibility for major tasks like manifold removal or heat exchanger service can be difficult and may require removing furniture components.
• Hydraulic Steering Seals: The Vetus or similar hydraulic systems used in these boats are reliable but prone to slow leaks at the ram or the helm pump after decades of use. Check for "play" in the wheel and fluid staining in the aft lazarette.

Community & Resources

While Ferretti has moved almost exclusively into the mega-yacht and high-speed motor yacht sectors, owners of the legacy Altura line are supported by a dedicated community. The most prominent resource is the Ferretti Altura Owners Group, a collective of European and American sailors who share technical manuals and restoration tips. Additionally, because the boats were primarily built in Forlì, Italy, much of the original technical wisdom is preserved in Italian forums such as Amici della Vela, where long-time owners discuss refits and the original factory specifications.

The Verdict

The Ferretti Altura 424 is a "gentleman’s cruiser" that prioritizes the journey over the destination. It is an ideal platform for a couple looking to live aboard or cruise the Mediterranean and Caribbean in a vessel that feels significantly larger and more substantial than its 42-foot LOA suggests.

Pros:

• Build Quality: Exceptional woodwork and fiberglass layup that puts modern production boats to shame.
• Visibility: The raised saloon provides a bright, airy living space with excellent views.
• Sea-Kindliness: A heavy, stable hull that inspires confidence in heavy weather.

Cons:

• Light Air Performance: The heavy displacement and ketch rig struggle in winds under 10 knots without engine assistance.
• Maintenance Intensity: Older teak decks and complex plumbing systems require a diligent (and well-funded) owner.
• Parts Sourcing: Some original Italian hardware and custom-molded interior pieces can be difficult to replace with off-the-shelf components.
