11. The patent-pending fins are based on 50 years of hydrodynamic research on the bulbous bow hull design. 12. I found the name : bulbous bow ! 13. The ships used bulbous bows and steam turbines to reach these high speeds while maintaining economical operating costs. 14. A far more radical bulbous bow design solution was incorporated into their massively large, including, and the aircraft carrier. 15. A modest bulbous bow was used in a number of their ship designs, including the light cruiser and the carriers and. 16. There is also one Corvette which has a retro-fitted extended bulbous bow , presumably to extend the waterline length to help efficiency. 17. The foreship of " Mastera " is designed for open water performance with a bulbous bow to maximize the hydrodynamic efficiency. 18. The foreship of " Tempera " is designed for open water performance with a bulbous bow to maximize the hydrodynamic efficiency. 19. It struck everyone by the novelty of its hull, that combined a Bulbous bow with the Clipper-style of the top of the hull. 20. The " Nimitz "-class ships constructed since also have bulbous bows in order to improve speed and fuel efficiency by reducing Wave-making resistance.
