The invention relates to a front-steering ship front steer and a steering hole enclosing apparatus. The steering hole enclosing apparatus comprises a steering power machine (2) disposed in a steering hole (1); two ends of a steering hole wall cylinder body (11) are respectively connected with a left closure housing (3) and a right closure housing (4); a spherical revolution body sealer (5) is disposed in inner holes of the left closure housing (3) and the right closure housing (4); rotating shafts (52) of the two spherical revolution body sealers (5) on the same side are respectively connected with a swinging arm (6); the two swinging arms (6) are respectively hinged with a connection rod (7); the other ends of the two connection rods (7) are respectively hinged with two ends of a cross beam (8); and the middle of the cross beam (8) is connected with a hydraulic cylinder (9). Two end hole ports of the steering hole are sealed by the steering hole enclosing apparatus, so resistance to the ship cannot be increased; ship body outer wall streamlined integrity can be maintained when the front steer is not used; and wastes can be prevented from entering the steering hole, so safety of equipment in the steering hole can be remained.
