A company specialises in marine aluminium sea works focused on boats, maritime works and marinas.

AISTER has been working in the marine industry for 30 years and during this period, we have developed the following business lines:

Aluminium Shipyard

We have the best engineers for aluminium professional boats to meet our customers’ needs. We sell our own models of patrol boats, passengers, workboats and rescue boats, and our customers include the Spanish Civil Guard, Maritime Safety and Rescue Society, and Military Emergency Unit.

Maritime Works

We have been part of Vigo’s marine industry for 30 years. During this time, we have delivered over 150 projects in areas such as marine interiors, thermal insulation, ship supply, aluminium superstructures and accommodation ladders for all types of ships, including seismic, scientific research, fishing and merchant vessels and luxury cruise liners.


We design and manufacture floating docks, aluminium gangways, fingers, breakwaters, cleats and service pedestals for marinas and harbours. We are market leaders with over 30,000 m of aluminium and concrete floating and fixed docks installed throughout the world.

 Aluminium Shipyard: our definition

At AISTER, we seek to combine aesthetics, comfort, navigability and durability in all our products and believe that marine-grade aluminium is key to doing so.

Our top-quality alloys and flawless welding ensures the material does not lose any of its mechanical properties. This makes our boats, superstructures and docks light, flexible, safe, strong and durable, with low maintenance costs and specific properties.

Our work can be found throughout Spain in cities like A Coruña, Vigo, Gijón, Avilés, Cantabria, Abra, Pasajes, Barcelona, Valencia, Murcia, Almería, Huelva, Cádiz, Ibiza, Palma de Mallorca and Las Palmas de Gran Canaria, and internationally in countries such as Portugal, France, Italy, China, Greece, Dubai, Oman, Brazil and Cape Verde.
