The present invention concerns a bulbous bow for a sea-going vessel, said bow comprising a load-carrying inner structure mounted at the stem of the vessel and an outer shell structure defining the hydrodynamic properties of the bulbous bow, wherein said outer shell structure is provided with a sub-structure for replaceably mounting on the inner structure. The invention further concerns a seagoing vessel comprising such bulbous bow as well as a method of producing a bulbous bow and a method of mounting or replacing a bulbous bow.
