Extensively upgraded

Turnkey, ready to go 

Off-grid cruising, very well equipped 

High-spec electrical system 

 Exceptional, extensively upgraded Astréa 42 Maestro – Never Chartered, Lightly Used and Professionally Equipped for Fully Autonomous Off-Grid Cruising.

Seahorses is a beautifully equipped 2021 Fountaine Pajot Astréa 42 Maestro, presented in the desirable three-cabin owner's layout with Oceanic options.

Never chartered and used exclusively for coastal cruising, she has been carefully equipped and upgraded by her owners to create an exceptionally capable, self-sufficient cruising catamaran. With a professionally engineered Victron electrical system, extensive lithium battery capacity, 1,600W of solar power, twin Integrel on-engine generators and a high-capacity watermaker, Seahorses offers an impressive degree of independence from marinas and shore power.Designed with extended cruising and comfortable liveaboard life in mind, she combines the renowned space and practicality of the Astréa 42 with an extensive specification that would be difficult and expensive to replicate.

Exceptional Off-Grid CapabilityOne of Seahorses' greatest strengths is her professionally installed and commissioned Victron and Integrel electrical system, designed to provide power for everyday onboard living without the need for a conventional generator or shore power.

Highlights include:

• 1,600W of marine-grade Solbian solar panels.

• 400Ah of 48V Victron LiFePO4 lithium battery capacity.

• 450Ah of dedicated 12V house battery capacity.

• Twin Integrel 9kW on-engine generators, providing up to 18kW of charging capacity.

• Victron Quattro 48V 10kVA inverter providing 230V throughout the yacht.

• Additional Victron 3kVA inverter as backup.

• Victron Lynx Smart BMS and distribution system.

• Schenker Smart 100 watermaker producing up to 100 litres per hour.

• Starlink satellite internet system installed and ready to use.

The system has been professionally installed and commissioned, providing excellent redundancy and the ability to operate the yacht's major onboard systems, including cooking, refrigeration, air conditioning and watermaking.

Comfortable Three-Cabin Maestro Layout

The desirable Maestro configuration provides a spacious owner's suite in the starboard hull, with two additional guest cabins in the port hull.

Both guest cabins and the owner's suite benefit from individual heads, providing excellent privacy and comfort for family and guests.

The interior offers a welcoming and practical living environment, with a spacious saloon, comfortable seating, a coffee table and excellent storage.

The fully equipped galley includes:

• Bosch electric oven.

• Two-ring induction hob.

• Microwave.

• Two-drawer Vitrifrigo refrigerator.

• Isotherm four-drawer freezer.

• UV-LED drinking water purification system.

• Additional appliances and equipment.

A particularly attractive feature is the fully electric specification, with no reliance on gas onboard.

For year-round comfort, four Frigomar inverter air-conditioning units provide heating and cooling throughout the yacht, including the saloon and cabins. A Hoover 9kg washing machine is also installed in the owner's heads.

Viewing

For anyone considering extended cruising, living aboard or exploring further afield, she offers a very attractive combination of comfort, capability and independence.
