The Amels Custom 426 is a 46-meter custom motor yacht built by Amels in the Netherlands and launched in 1993. Known as Maupiti, later Karima, and eventually MMM, the yacht was designed with a strong emphasis on exploration, long-range cruising, and operational flexibility.
Unlike a conventional luxury production yacht, Custom 426 was developed as an expedition-oriented vessel capable of extended voyages. Its substantial volume, robust construction, and practical layout make it suitable for owners who prioritize global exploration, onboard space, and reliable ocean-going capability.
Is the Amels Custom 426 for Sale?
The Amels Custom 426 is a custom-built yacht rather than a current production model, so it is not normally offered as a standard new yacht. Its brokerage availability depends on whether the owner decides to sell, and specialist superyacht brokers are generally the best source for checking current availability.
Because the yacht was built in 1993 and has subsequently changed names and undergone updates, buyers should pay particular attention to its ownership history, refit records, classification status, and current technical condition before considering a transaction.
Amels Custom 426 Price
The price of an Amels Custom 426 depends heavily on its current condition, refit history, equipment, classification, and market circumstances. As an older custom superyacht, its value should be assessed individually rather than compared directly with the price of a new Amels yacht.
The purchase budget should also include potential refit expenses. For a yacht of this age and size, major systems such as engines, generators, electrical equipment, HVAC, navigation systems, and interior finishes may require upgrading depending on previous maintenance and refurbishment.
Performance and Propulsion
The Amels Custom 426 is powered by three Caterpillar 3508TA diesel engines, with published specifications listing a maximum speed of approximately 14 knots and a service speed of around 12 knots. The yacht has a reported range suitable for extended cruising, supporting its expedition-oriented design.
Its propulsion configuration emphasizes reliability and operational flexibility rather than high-speed performance. The combination of a robust hull and multiple engines makes the yacht well suited to long-distance cruising, remote destinations, and extended time at sea.
Exterior Design and Construction
The exterior of the Amels Custom 426 reflects the practical character of an expedition-oriented superyacht, with substantial deck space and a functional profile. Its approximately 46-meter length and 9.21-meter beam provide considerable volume for outdoor activities, tenders, equipment, and guest areas.
The yacht was built by Amels Holland in Makkum, Netherlands, with a steel-based construction suited to demanding ocean operations. Its robust engineering and practical deck arrangement distinguish it from yachts designed primarily for high-speed cruising or purely recreational use.
Interior and Accommodation
The Amels Custom 426 provides generous interior volume for a yacht of its size. Published specifications list accommodation for 12 guests in five guest cabins, supported by space for approximately 14 crew members, allowing the yacht to operate comfortably on extended voyages.
Its interior is better suited to long-term cruising than short coastal trips, with sufficient accommodation and service areas for extended stays. The yacht's expedition-oriented character also allows owners to use the interior and deck spaces for a combination of private living, entertainment, and adventure-focused activities.
What to Check Before Buying an Amels Custom 426
Before purchasing an Amels Custom 426, buyers should conduct a comprehensive survey covering the hull, propulsion system, generators, electrical infrastructure, navigation equipment, HVAC, plumbing, and stabilization systems. The condition of the steel hull should receive particular attention, including corrosion protection and any previous structural repairs.
Given the yacht's 1993 construction date, its refit and maintenance history is especially important. Buyers should review classification records, engine service history, previous refits, safety equipment, and current compliance documentation. A detailed technical inspection and realistic refit budget are essential before committing to an older custom superyacht.
