Abstract: Provided are a specification determination method of a fiber reinforced member having excellent fatigue resistance that allows ensuring sufficient pressure resistance while appropriately maintaining expansion characteristics of a marine hose and a method of producing the marine hose. A twist coefficient K of fiber cords (10) constituting a fiber reinforced member (9) having a cord fabric structure is set to 1900 or more and 2900 or less with a specification of twisting three or four filaments (10a) made of polyester, an interrelationship R between a predetermined elongation ratio E2 of a plurality of types of the fiber cords (10) having different specifications and a hose elongation ratio E1 in a predetermined expansion test of each of marine hoses (1) in which the fiber reinforced member (9) including the respective fiber cords (10) as constituent members is embedded as reinforcing layers (4A and 6A) is grasped in advance, a threshold Th of the predetermined elongation ratio E2 is set based on a standard value of the hose elongation ratio E1 in the predetermined expansion test and the interrelationship R and the predetermined elongation ratio E2 of the fiber cords (10) used as the reinforcing layers (4A and 6A) is set to the threshold Th or less.
