1977 Astilleros Custom

This 146-foot steel motor yacht was built by Astilleros in 1977 and underwent extensive reconstruction in 2007 at Balk Shipyards in the Netherlands. The rebuild brought the boat to modern construction standards, including Unrestricted Navigation Classification compliance and zero-speed stabilizers. Twin MTU diesel engines producing 1,860 hp drive the yacht to a maximum speed of 14 knots, with a cruising speed of 12 knots and fuel consumption of roughly 150 liters per hour, supporting a transoceanic range of 3,500 nautical miles.

The yacht accommodates nine cabins and ten heads, making it suitable for family cruising or charter operations. The steel hull and aluminum superstructure are designed for efficiency in blue water conditions. The aft bridge deck spans 853 square feet and includes a 2.5-ton crane, providing substantial space for tender storage and equipment deployment uncommon in yachts of this size.

The yacht's configuration reflects its history as both a charter vessel and long-range expedition platform. It has supported technical diving operations and exploration work, with accommodation for specialized equipment including diving gear and space for a submersible. The boat has operated successfully in Mediterranean and Southeast Asian waters under previous ownership, demonstrating proven capability for extended passages and demanding cruising profiles.
