RIS MARINE Sportnautik from Zagreb is the successor of Maestral from Gradačac; one of the oldest and most renowned manufactured of inflatable boats in Croatia and in Southeastern Europe established 50 years ago. Some products from company's range, such as Hypalon Neoprene tubes, are still manufactured in the production plant in Gradačac while the production of fibreglass bottoms as well as the assembly and equipping of vessels is done in Zagreb. One of the main visions of the company, to establish the respectable brand was achieved by combining tradition with the state-of-the-art production technology, extensive quality control and investment into design and production of new boat types. In the past two years the company launched five new boat types on the market. Innovative solutions of the hull resulted in improved stability of the vessel which can be equipped with low-power engines and travel at higher speed compared with boats with engines of the same power. Hand-made boats of RIS MARINE Sportnautik are unique on our market and are a worthy investment. All our vessels are awarded the Germanische Lloyd certificate.

The production range includes thirty boat types and special-purpose vessels (navy, coastguard) as well as exclusive luxury boats and yachts with auxiliary equipment and inboard petrol or diesel engines.

- Dinghies are small but very practical. Due to their small weight they are easily manageable even by women and children. They can be used as auxiliary boats on larger yachts and sailing boats. The dinghy can be equipped with outboard engine which is mounted on reinforced transom. The flooring is made of strong, Hypalon Neoprene reinforced fabric. When deflated the dinghy is compact enough to fit the trunk of your car.

-Sports boats are somewhat larger than dinghies and are manufactured in three versions: Leader 9.2, Leader 10.2 and Leader 11.2. The boats have non-slip plasticised plywood floors, v-shaped keels and clad transoms. They are easily assembled and very stable in sailing.

- Rigid-inflatable boats (RIBs) with fibreglass bottom are also manufactured in three versions: Leader 35 F, Leader 50 F and Leader 80F. They are easy to transport and very manageable and stable even during harshest weather conditions. They feature exceptional peak speeds and optimal fuel consumption rate.

- RIBs 99 are new types of rigid inflatable boats in our production range. Their main characteristics are high performance, high speeds with low power engine and additional equipment upon customers' requests.

- RIBs 850 are rigid-inflatable boats that can be equipped with inboard and outboard engines upon customers' requests. The tubes are made of Hypalon Neoprene blend weighing 1760 g/m. The fibreglass construction allows higher speeds n all maritime conditions. The largest allowed load is 5.133 tons. The vessel can accommodate 32 passengers, according to ISO 6185-3. Standard. With 12 passengers aboard and the complete equipment the vessel can travel at 42 knots. The maximal speed of the vessel is 60 knots.

- Life-saving boats F 1 and F 2 are easily and quickly assembled because all components are attached to boat frame. They are very stable and can be safely used at open sea. The chambers are set considerably high but not too wide and the boat can be easily inflated.

- Rafting boats with v-shaped keel and double-air floor are manufactured in different lengths (3.5, 4, 4.5 and 5.20 meters) and chamber diameter of 50 cm.

- Banana boats are inflatable, unpowered boats designed for five or more adults.
