Aluminum deep V hull bottom shape with moderate transom deadrise with wide bow lines give optimal sea-keeping ability, especially in heavy seas. At the same time prismatic hull shape provides more stable deck surface, while moving around the superstructure. Deck without steps and obstacles is good for prompt and urgent operations, working and moving the equipment on the deck, MOB rescue.
Wide hull beam (3,3m) gives SWR-120 good payload capacity and more space inside and outside for systems and special equipment; more cabin space. With moderate draught of 0,80m and waterjets the boat can be freely used in shallow waters close to the shore.
A lot of different equipment designed and installed makes the boat really multi-purpose: rigid fender, hydraulic crane, safety rail, aft rescue platform, quick-release hook, dry-break coupling fuel filling system, windshield washers, separate genset and battery charger, windows heating, thermo-camera, AIS, GMDSS radio-navigation for A2 area, separate FF pump, twin diesels paired with waterjets.
1600l of diesel fuel provide quite a long range of 380 miles and fresh/hot water supply together with the fully equipped galley open the opportunity to operate for a long period without coming back to the shore.
Additionally the boat is designed to be self-righting and has all the needed systems for that.
