The Astondoa Group can also offer facilities such as Marina Astondoa as a bonus for its customers.  This is a facility with 40 berths that can be used during a technical support visit or simply as a courtesy to anyone with an Astondoa yacht.

Aware of the lack of available moorings, Astondoa has created a venture known as "Miramar Marina" whose purpose is the construction and development of new marinas.  The first project of this venture is Miramar Marina, a complex for the mooring of vessels up to 156 feet in length with a total of 260 berths and that also has a restaurant, cafe, parking, and commercial facilities for port services.

Innovative design and quality of execution allows Astondoa to stay at the forefront of development of marine infrastructure in Spain.
