"Okyalos Open 14" & "Okyalos Closed 10” are two high speed vessels which can be very easily used for military purposes because of their characteristics and armament they can carry (Fig. 1 & 2). Their development is based on the prototype (Fig. 3) launched, tested and adopted by Hellenic Navy on June 2015. However, they differ from the prototype vessel at the following aspects: ^ Weight saving through optimization of structure. ^ Optimization of cruising and safety...

It's made of Aluminum Alloy 5083 while some standard reinforcing structural members are made of Aluminum Alloy 6082 (both alloys are ideal for ship building. The structure is a combination of frames (primary structural parts) and longerons (Fig.5).

! Fig.5: Vessel Structure The boat is covered by a deck and has five (5) internal bulkheads (Fig.6). The boat compartments are: ➢ Engine Room ➢ Fuel Tank ➢ Passenger Cabin (Closed 10) ➢ Cockpit ➢ Cargo Hold ➢ Bow Water-Tight ! Fig.6: Boat Compartments - Projection The engine room and the fuel tank are easily accessible through removable doors (covers). Fuel tank itself is also removable and made of aluminum. Two pairs of spray rails (strakes) are mounted on the bottom of the hull. Furthermore, the boat is equipped with safety rails (on the deck), a platform (at the stern) and full...

Efficiency Propulsion system advantages are as follows: ! Fig.8: Propulsion System Comparison ➢ 15% to 30% speed increase over conventional systems. ➢ 15% to 30% increase in fuel efficiency. ➢ More efficient than I/O’s ➢ Corrosion resistant ➢ Size adaptability, from 100 hp to over 10,000 hp applications. ➢ Low maintenance requirements. ➢ Ability to adjust propeller submergence while underway. ➢ Ability to adjust submergence to match horsepower output permits conversion of more thrust as appropriately needed. ➢ Propellers ventilate to the surface rather than cavitate under the hull reducing...

Propulsion system basic features and capabilities are as follows: Trimable Propeller Shaft The propeller shaft is vertically adjustable, allowing selection of the optimum thrust angle for varying load and sea conditions. Positive Thrust Steering Unlike conventional systems that vector prop thrust off of a rudder, the Arneson Surface Drive angles in the direction of motion, maximizing steering control and response. Responsive Maneuverability Propellers are located aft, behind the hull, increasing steering leverage and improving maneuverability at all speeds. Shallow Water Capabilities The...
