Only two hulls were ever built of the Sanlorenzo 40 Alloy platform — and after the 2024 Hot Lab refit of M/Y Naia, one of them is now the most uniquely positioned 38-metre charter yacht in the Aegean. Full platform specs, charter rates, and the story of the refit.
The Sanlorenzo 40 Alloy is one of the rarest superyacht platforms in active charter — Sanlorenzo only ever built two hulls of the type, and both remain in private operation. The first was Naia (delivered 2009, refitted in 2024 by Milan's Hot Lab Studio). The second was Aslec (delivered 2011, in private use). For HNWI charterers searching for a 38-metre Mediterranean yacht with a distinctive design DNA — Italian aluminium architecture by Francesco Paszkowski, refit-grade contemporary interiors, full-displacement sea-keeping — Naia is, in 2026, the platform's only charter option. This guide explains why that matters.
What is the Sanlorenzo 40 Alloy?
The 40 Alloy is a 38.5-metre aluminium-hulled tri-deck motor yacht designed by Francesco Paszkowski (exterior) for Sanlorenzo's La Spezia yard. The platform was launched in 2009 as Sanlorenzo's bid for the 30-40m semi-displacement market — light enough at 250 GT to slip into Mediterranean marinas other 40m yachts couldn't access, but with the seakeeping of a full-displacement vessel thanks to a robust aluminium hull and zero-speed stabilisers active both at anchor and underway.
Hull and superstructure are entirely aluminium — unusual for Sanlorenzo, whose mainstream production at the time was composite. The aluminium choice gives the platform a 30% weight advantage over comparable steel-hulled 38m yachts, translating to a meaningful charter benefit: roughly 2 knots higher cruising speed for the same fuel burn, and a draft of just 2.1m that opens up Aegean anchorages no Lürssen or Feadship of comparable internal volume can reach.
Specifications
Length overall: 38.5 metres. Beam: 8.0 metres. Draft: 2.1 metres. Gross tonnage: 250 GT. Hull: aluminium. Superstructure: aluminium. Engines: Twin MTU 12V 2000 M70 (1,520 hp each). Cruise speed: 14 knots. Maximum speed: 17 knots. Range at cruise: 4,500 nm. Fuel capacity: 38,000 litres. Water capacity: 9,500 litres. Stabilisers: zero-speed + underway. Classification: RINA charter compliance.
Accommodation across both hulls is configured for ten guests in five en-suite cabins on the lower deck: full-beam Master, full-beam VIP, two doubles, one twin convertible to double. Crew of eight (captain, chief engineer, chief stewardess, chef, two stewardesses, deckhand, watersports instructor) accommodated forward on the lower deck.
The Hot Lab 2024 refit on Naia
What separates Naia from Aslec — and from every other 38m yacht in the Aegean charter market — is the 2024 Hot Lab refit. Sanlorenzo's Style Director Sergio Buttiglieri commissioned Hot Lab Milan (the same studio that designs Bilgin 163 interiors) to bring Naia's 2009 interior into 2026 condition.
The refit was structural-tier, not cosmetic: full re-engineering of the master suite into a contemporary owner's wing with walk-in dressing, hull windows that bring the Aegean to bed-level, and a freestanding marble tub. The main salon was rebuilt around floor-to-ceiling glass on three sides, Italian custom furniture, sculptural chandelier hand-made in Murano. Beach club aft was opened up to twin fold-down platforms creating a 60 m² sea-level space when deployed. New stabilisers, new tender (an Axopar 37 XC Cross Cabin chase boat that opens up bays inaccessible to the mothership), new AV systems throughout.
The result is the only Sanlorenzo 40 Alloy in active charter with a 2024-grade contemporary interior — a unique value proposition that Mogul Yachts uses as the centrepiece of Naia's charter positioning.
Charter rates and availability
M/Y Naia charters at €130,000 per week plus 30% APA (Advance Provisioning Allowance). Greek VAT (12% in Greek waters) and Turkish VAT (8% in Turkish waters) applied per route. Operated from Athens base seasonally with cruises to the Cyclades, the Ionian, the Dodecanese with optional Turkish Riviera extension. 2026 summer weeks are released — Mogul Yachts is the central agent. Aegean Summer 2027 booking opens September 2026.
The other hull: Aslec (private)
Aslec is the second and final 40 Alloy hull, delivered to a private Italian owner in 2011. She has remained in private use since launch and is not available for charter. Her presence in the platform's pedigree matters for charter context — it demonstrates that the 40 Alloy attracted owners willing to commission very specific design briefs (Aslec's interior was custom-designed by Liaigre, where Naia's was Sanlorenzo's standard 2009 fit-out before the 2024 Hot Lab refit). Two hulls, two design eras, one platform.
How the 40 Alloy compares
At 38.5m and 250 GT, Naia sits below the 500 GT regulatory threshold that triggers additional crew certification and port restrictions — meaning her operational flexibility in the Aegean is closer to that of a 30m yacht than a 50m one. She slips into Hydra, Folegandros, and Patmos anchorages that the larger Bilgin 163 or 50m Sanlorenzo SD126 cannot enter. Speed advantage over steel-hulled 38m vessels gives her ~2 knots more cruise — equivalent to one extra anchorage per 7-day charter.
Charter rate of €130k/week sits below the €200k threshold where the next class of competitor (60m+ vessels) starts. For HNWI families and group charterers wanting genuine 38m capacity without 50m operational friction and 60m pricing, Naia is the singular Aegean option in 2026.
“The 40 Alloy is rare for a reason — Sanlorenzo built two and stopped because the next platform (the SL120A in composite) was cheaper to produce. Owning or chartering one means experiencing a yacht type that won't be made again.”
