The Dullia 30 is a classic Italian cruiser-racer from the late 1970s, a period defined by the design influences of the International Offshore Rule (IOR). Conceived by the renowned Italian designer Ettore Santarelli and built by Cantiere Dullia in Lombardy, this 30-foot monohull was produced from approximately 1977 through the early 1990s. It stands as a representative of the "Made in Italy" era of yachting, balancing a robust, heavy-weather hull with a functional, timber-rich interior. While many were produced for the Mediterranean market, its reputation for stiffness and reliable tracking has made it a persistent sight in European coastal waters.

Sailing Performance & Handling

The Dullia 30 is characterized by its significant ballast-to-displacement ratio, often cited near 60%, which translates to an exceptionally stiff and stable platform. This high righting moment allows the boat to carry full sail longer than many contemporary light-displacement cruisers. Rigged as a masthead sloop, the boat utilizes a simple and robust sail plan that favors control over raw light-air speed.

Under sail, the boat exhibits the classic handling traits of an Ettore Santarelli design: it is responsive yet predictable. The combination of a deep fin keel and a spade rudder provides high maneuverability in tight quarters, though the IOR-influenced hull—with its wide beam carried amidships and relatively pinched ends—can lead to "hobby-horsing" in a short chop if not properly balanced. While technical ratios suggest it is a moderate-displacement vessel with a theoretical hull speed of approximately 6.5 knots, it is known to perform well on a beat, pointing high and maintaining momentum through the waves.

Interior Comfort & Variations

The interior of the Dullia 30 reflects the craftsmanship of the Italian yard, featuring extensive use of mahogany and a layout designed to maximize the 3.15-meter beam. The standard configuration includes a forward V-berth, a central salon with a folding table that converts into additional berths, and a compact but functional L-shaped galley to port. A dedicated navigation station is typically situated to starboard, adjacent to the companionway, providing a professional workspace for coastal passage making.

Several variants of the hull exist, most notably the Dullia 30 S (Sport). While the standard model was marketed as a comfortable family cruiser, the "S" variant often featured a taller mast and a deeper, more refined keel profile to appeal to the regatta circuit. Internally, the "S" models occasionally opted for lighter-weight materials and a more open-plan cabin to reduce weight, though both versions maintained a level of "Italian styling" that was considered upscale for its time.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the Dullia 30 with a focus on structural aging common to fiberglass boats of this vintage.

  • Keel-to-Hull Joint: Due to the high ballast ratio, the stress on the keel bolts and the surrounding fiberglass stub is significant. Inspect for "smile" cracking at the forward edge of the keel joint or evidence of weeping around the bolts in the bilge.
  • Deck Core Integrity: The decks were constructed using a sandwich core that can be prone to delamination. Pay close attention to soft spots around high-load areas such as the chainplates and the mast step.
  • Mast Step Compression: On some units, the wooden or composite block beneath the compression post can deteriorate over decades, leading to a slight "sag" in the deck or difficulty opening the head or V-berth doors.
  • Osmosis: Early Italian GRP production can be susceptible to osmotic blistering. A moisture meter test on the hull below the waterline is highly recommended during a survey.

Community & Resources

As a staple of the 1980s Italian sailing scene, technical information and owner discussions for the Dullia 30 are frequently found within the archives of Giornale della Vela, which has documented the shipyard's history and Santarelli's contributions to naval architecture. Owners often congregate in Italian-language technical forums such as "Amici della Vela," where specific maintenance tips regarding the Farymann or Volvo Penta engines typically found in these boats are discussed.

The Verdict

The Dullia 30 is a stout, "over-built" cruiser that offers a level of safety and stiffness rarely found in modern light-weight production boats of the same length.

Pros:

  • Extremely stiff and stable due to a high ballast ratio.
  • High-quality Italian interior woodwork and classic styling.
  • Predictable handling and good upwind performance.

Cons:

  • Pinching at the bow and stern can lead to hobby-horsing in certain sea states.
  • Original engines (often Farymann) may be nearing the end of their service life.
  • Older GRP construction requires careful inspection for osmosis and core wetness.
