“OKYALOS” according to Greek mythology is the one that moves the most rapidly on the water while according to the greatest of the epic poets, Homer, “Okyalos” was the name of Odysseus’ battle ship.
Our company’s product portfolio is proudly incorporating OKYALOS, a unique, state-of- the-art, rigid, monohull aluminium boat of 15m length that can satisfy innumerable applications and missions, while able to perform at the maximum speed of 50 – 55kts with exceptional stability and maneuverability. Indicatively, this high-speed multi-purpose vessel capable of operating in closed and open sea, under harsh environmental conditions, has advanced characteristics and abundant customization capabilities that enable it to adjust easily, cost-effectively and with great flexibility and agility to a vast variety of operational cases and applications:

OKYALOS is characterized by its plurality of comparative advantages in relation to ribs or other material boats:
- Manufactured with the top quality aluminum used worldwide in shipbuilding
- Classified by Bureau Veritas (BV)
- A miniature frigate (frigates capabilities at a flexible size, with respectively low functional and maintenance costs)
- Fine design and shipbuilding by technology-artists engineers
- Customization capabilities which allow uncomplicated changing of equipment, purpose, applications
- Long-time lifespan (min 30years)
- Bulkheads that mitigate the possibility of sinking
- A set of inflatable tubes surrounds its aluminum hull, which adds to its stability and seaworthiness, while is very helpful for touch n go or divers pickup operations
- Inboard engines (professional, reliable, diesel, of greater horsepower and lower maintenance cost)
- Optimal selection of thrust system adapted from racing crafts
- Special design anti-vibration seats so to ease fatigue over long top speed cruises with technology adapted from racing off road motorbikes.
- Separately installed, easily removable, aluminum fuel tanks.
- Quick easy damage repair/inspection (or battle damage repair for military versions)
- Manufactured in Europe

- Corrosion Resistant
- Low Maintenance Cost. Checking the condition and changing sacrificial anodes (zinc or magnesium) regularly, the structure can be prevented from the corrosive environment.
- The naval alloys 5000 and 6000 series are known for their high strength, corrosion resistance, and good elasticity.
- An aluminum boat is estimated to have a life span of more than 30 years.
Weight Fuel Speed
- The low density of aluminum, combined with high strength, toughness, and corrosion resistance, allow vessel designers to achieve weight savings of 20-30% over GRP designs.
- Weight savings equate to higher speed and less fuel consumption.
- GRP material is extremely brittle while aluminum has considerable ductility.
- In case of strong impacts, the GRP may faces cracking and fracture while aluminum can support impact loads without detrimental permanent deformation.
- Aluminum is not affected by Ultraviolet (UV) radiation while GRP ages over the time increasing the point of brittleness. The higher the brittleness, the higher the possibility of cracking in case of impacts.
- Over two-thirds of all the aluminum ever produced is still in use today.
- GRP cannot be recycled at all.
- GRP boats contain petroleum based resins which are flammable. In order to face the problem of fire, fire retardant resins are used to make fire more difficult to start.
- Aluminum is described as non-combustible (British Standard BS476). The same set of standards gives aluminum high marks on the fire resistance versus spreading scale.
- Many GRP boats are often not constructed in well controlled temperature buildings leading to the widespread problem of fiberglass pox.
- Affects negatively boats life.
- The life time of an aluminum boat is about double that of the GRP.
- Aluminum boats are preferred in hard jobs because the repair procedure is easy and quick.
- Widespread use (Military, Landing crafts, Lifeguards and many Fishing boats are made from aluminum) because a small scratch or hitting can be fixed in a few minutes.
Raw Material Origin
- Used Aluminum is produced in Greece. Superior quality. The most extensively used in shipbuilding worldwide
