    摘要： A method of manufacturing a marine hose that includes a sponge layer and has good appearance. The marine hose includes at least a base hose (2), a sponge layer, a foam rubber layer, and a cover rubber layer (3). The method comprising the steps of:
    wrapping a sponge layer (A) around the outside of the base hose 2;
    wrapping a foam rubber layer (B) around the outside of the sponge layer (A), the foam rubber layer (B) containing an unvulcanized foam rubber composition;
    wrapping a cover rubber layer (3) around the outside of the foam rubber layer (B); and
    vulcanizing the wrapped assembly; wherein
    the foam rubber composition includes
    a rubber component containing as a main component at least one selected from the group consisting of natural rubber, styrene butadiene rubber, chloroprene rubber, ethylene propylene rubber, ethylene propylene diene rubber, and
    reclaimed rubber;
    and, per 100 parts by mass of the rubber component, from 1.1 to 50 parts by mass of a blowing agent and from 1.1 to 50 parts by mass of a blowing aid; and a blow ratio of the foam rubber composition after vulcanization is 1.1 or greater.

    摘要： Provided is a marine hose line and a marine hose that avoid increasing the diameter and reducing the flexibility of the hose body portion, and is capable of preventing the marine hose line from sinking to a water bottom, even if an end portion of the marine hose line let out onto water from a take-up reel is cut off from a coupling and falls to the surface of the water.
    A sinking-resisting device 8 installed on an end portion on the take-up reel 14 side of the marine hose line L, includes a sinking-resisting body 10 installed on the outer surface of the marine hose line L in a folded-up state, and an expander 11 that expands the folded-up sinking-resisting body 10. After the end portion of the marine hose line L is cut off from the coupling 15, the expander 11 is activated to expand the folded-up sinking-resisting body 10, and the drag from the expanded sinking-resisting body 10 in the water prevents the end portion of the marine hose line L from sinking.
