Provided are a marine hose and an airbag device for a marine hose able to prevent sinking of a marine hose line to the bottom of a body of water due to a decrease over time in buoyancy, while preventing an increase in diameter and decrease in flexibility of a main hose body. An airbag device 8 including a water pressure sensor 9, a folded bag float 10 attached to the outer surface of the marine hose 1, and an inflation device 11 for introducing air into the bag float 10, is used, wherein the water pressure sensor 9 activates the inflation device 11 to inflate the folded bag float 10 when the water pressure sensor 9 detects that a preset water pressure value has been reached, the buoyancy provided by the inflated bag float 10 preventing further sinking of the marine hose 1.
