About LADY DIA

LADY DIA is a 42-metre motor yacht built by Custom Line in 2025 to the Custom Line 140 model, with exterior design by Francesco Paszkowski Design and interior design by the Ferretti Group Engineering Department. As a newly delivered vessel within the Ferretti Group's Custom Line semi-custom programme, she represents current production standards from one of Italy's most established volume builders at the larger end of the series.

She accommodates 10 guests across 5 cabins with a crew of 7, a configuration well-suited to a single extended family or close group. Her charter regions cover the western Mediterranean: the French Riviera, Monaco, Cannes, Corsica, Sardinia, St Tropez, and the Italian coast. The Custom Line 140 is not a long-range passage-maker, with a recorded range of 700 nautical miles, so LADY DIA is best matched to guests planning day-by-day coastal programmes rather than extended ocean itineraries.

The Custom Line 140 platform is a GRP semi-displacement design, capable of 18 knots cruise and 21 knots maximum, offering a meaningful step in transit speed compared to pure displacement yachts without the fuel consumption penalties of full-planing hulls. Francesco Paszkowski's exterior gives her a contemporary Italian profile consistent with the upper end of the Custom Line range. Underway and at-anchor stabilisers, a hydraulic swim platform, deck jacuzzi, sun deck, foredeck seating, exterior bar, sunpads, and full air conditioning represent a well-specified amenity package for a 2025 delivery.

Water access on LADY DIA is facilitated by the hydraulic swim platform, with a toy inventory that includes seabobs, a Yamaha jet-ski, wakesurf, wake board, and snorkelling equipment. The exterior bar, sun deck, and deck jacuzzi extend the social dimension of the al fresco spaces central to a western Mediterranean charter programme. With 7 crew managing 10 guests, the service model on this charter yacht is professional and attentive within the compact elegance of the Custom Line 140 layout.

The provisional rating is based on available public data, reflecting acceptable standards across safety documentation, maintenance records, and operational protocols. As an independent authority, RightYacht provides owners and charterers with transparent, third-party evaluation — helping inform decisions beyond marketing materials alone.

About This Score

This is a provisional score based on publicly available data only. Unlike verified yachts, this listing lacks:

  • Independent on-board inspection
  • Crew qualification verification
  • Maintenance record audit
  • Safety equipment inspection

The actual safety profile may differ significantly.

Provisional scores are calculated from eight factors: vessel age, refit recency, classification society, flag state, crew-to-guest ratio, builder reputation, vessel size, and charter region coverage. All provisional scores are capped at 75/100. Learn how scores work →
