When you purchase, work with a certified installer who can tailor them to the Sanlorenzo 45m hull and ensure the electrical interfaces are integrated with on-board systems for remote diagnostics. This combination helps you successfully manage dynamic seas and marina approaches.

Deck layouts provide flexible access to tenders and water toys, with a forward sun area and an aft lounge. A coral palette appears in fabrics and soft furnishings, creating coherence from the master suite to the guest decks. Plan occasional stays for guests with a dedicated dining terrace and shaded corners for relaxing after a day at sea, while marinas offer protected mooring and easy embarkation for your crew and charterers.

General Arrangement Plans for the 45m Sanlorenzo Yacht: Practical Reference

Design a two-deck General Arrangement with the owner’s suite on the main deck and five guest cabins on the lower deck to host 10–12 guests, while keeping crew areas efficient and separated. Prioritize a full-beam saloon, a formal dining area for 12, and a forward-facing galley that minimizes staff traffic in guest spaces. The hull spaces should include a dedicated gym, a spa, and a tender bay on the lower deck, all reachable via central stairs and a service lift. This layout delivers excellent circulation and simple service flows for daily operations.

Levels and circulation: allocate three functional levels below the bridge deck, with the upper deck offering exterior lounges and the foredeck dining area. The sundeck should host a pool, sunbathing lounges, and a shaded dining space. Keep a separate crew mess on the lower deck, with direct access to the engine room and laundry. This distribution matches modern superyacht usage and aligns with guest, crew, and owner preferences for privacy and social zones.

Interior and exterior design: Zuccon provides the exterior lines that present a clean, modern profile with a generous midship beam for stability. The interiors, guided by farzan, emphasize warm materials, abundant natural light, and humidity control. Guests enjoy fresh air on exterior decks while indoor spaces stay climate-controlled. The design supports flexible use, including a configurable formal dining area and a gym that can transform into a cinema for evenings onboard.

Propulsion and performance: choose a modern propulsion package that balances fuel efficiency and speed targets. A pair of high-efficiency diesels with shaft drives delivers 12–14 knots in economy mode and 16–18 knots at higher speeds, with a top end near 20 knots. Fuel capacity around 60,000–70,000 liters supports 3,000–3,600 nautical miles at 12 knots, depending on load and sea state. Consider a Mercury-assisted bow or stern thruster for tight docking while keeping main propulsion MTU-based or another OEM option; this hybrid approach improves maneuverability in reef-rich waters.

Exteriors and fittings: available exterior coatings and finish options influence the price, with selection typically affecting total outlay by 15–25% for a full custom fit-out. For a warm interior and durable finish, choose a zuccon-designed exterior with interior details by farzan. The available configurations enable a smooth transition from formal dining to informal lounges, while a forward guest area keeps noise away from the owner’s suite. A multi-zone climate system maintains humidity levels and comfort across all spaces.

Operational notes: in warm tropical climates near reefs, ensure hull protection, corrosion resistance, and reliable fresh-water flushing for essential systems. Plan a robust spares strategy and a trade-ready procurement list to minimize dockside downtime. The GA should include a modular tender bay for a 9–12 m boat and a reef-ready mooring setup, ensuring readiness for diverse itineraries and port calls while preserving hull integrity.

Summary: this reference highlights how hull design, space allocation, propulsion choices, and interior styling converge on a practical 45m Sanlorenzo GA. The exterior lines by zuccon, warmed by farzan interiors, create a modern yet welcoming feel that suits a range of preferences and budgets. Availability of different configurations enables a tailored package that remains excellent for long-range cruising, with a resort-like atmosphere and dependable systems for comfort and reliability at sea.

GA Scope and Boundaries: Hull, Decks, and Core Systems

Set the hull boundary and core-system packages now to prevent scope creep and creating predictable maintenance cycles for long-range voyaging toward any destination.

The GA scope is organized into Hull, Decks, and Core Systems, with precise boundaries that guide construction and inspection. Hull covers plating, frames, keel, bulkheads, ballast, and tanks, while Decks include the main deck, deckhouse interfaces, watertight doors, and safety rails. Core Systems encompass propulsion, power distribution, generators, electrical networks, HVAC, freshwater and wastewater handling, and essential auxiliaries that provide reliable operation and comfort.

Stabilisers tie into hull framing and the superstructure, providing active dampening for pitch and roll. Ensure the hydraulic lines, control valves, and sensor networks align with the propulsion and power systems so the response remains rapid under demanding seas. This approach provides the most stable baseline for guest comfort and crew safety. It also supports chasing rougher seas with fewer vibrations, maintaining a steady image aboard during challenging passages.

For entertaining and cruising plans seeking diverse activities, plan access routes that support quick shifts from living spaces to sports equipment storage and tender bays. From the galley to cabins, maintain intuitive service paths that keep meals flowing and guests comfortable. The port approach, nearby islands, and open-water routes should factor in occasional weather changes and image-conscious layouts that minimize motion and maximize crew efficiency, in line with countrys regulations and certifications for hull strength, fuel handling, and life-support systems.

This scope framing could support disciplined planning and connect propulsion, accommodations, and entertainment goals with a robust marine footprint across ports and open-water legs. This does not add unnecessary complexity.

Deck Layouts: Main, Upper, and Lower Deck Public Spaces

Position the main deck salon as the central gathering hub with direct, weather-protected access to the exterior dining area to maximize guest flow and day-to-day livability.

The Main Deck Public Spaces balance luxury and practicality. The salon flows into the dining area with a single, open deck plane, while panoramic windows frame landscapes and calm horizons. A discreet bar along the port side serves guests without interrupting sightlines, and the exterior terrace extends the social zone for al fresco meals when weather allows. Seating in the salon accommodates 12–14 guests, with a secondary cluster for smaller groups of 6–8 around a coffee table. A dedicated ski/water toy locker on the exterior deck handles occasional gear, so this storage stays out of the living spaces. Mercury-tone upholstery and luxe finishes–stone, brushed metal, and warm woods–support a timeless style that couples comfort with high-end luxury. For visit by charterers or local guests, this layout provides a flexible baseline. Typically, the flow supports easy movement between seating clusters and the dining area, which is crucial for guests seeking privacy or a shared social moment. Shafts for stairs and services stay tucked in chases to preserve clean lines and safety.

The Upper Deck Public Spaces provide elevated social options with a focus on flexible use and views.
