PURPOSE:To realize a good durability and an economy, by making the upper part and the lower part of a mooring line which are connected to a light buoy and to a sinker weight respectively into chains, while making the middle part of the mooring line into a fiber rope, and making the upper half of the fiber rope mooring line heaver than the seawater while the lower half lighter than the seawater in the specific gravity. CONSTITUTION:The upper mooring line 3 connected to a light buoy 1, and the lower mooring line 4 connected to a sinker weight 2 are made into chains, while the upper part 5 and the lower part 6 of the intermediate mooring line are made of a fiber rope. The upper part 5 is made heavier than the seawater while the lower part 6 is made lighter than the seawater in the specific gravity. Therefore, a weight to erect the light buoy 1 can be omitted, the mooring line can be made bearable securely to severe shocks of waves and the like, preventive to a kink and abrasion, and the lower chain mooring line 4 near the weight 2 is prevented from abrasion and damage. Moreover, the upper intermediate line 5 does not float up to the sea level, and the lower intermediate line 6 neither sinks to touch the sea bed nor floats up to the sea level. Therefore, the whole mooring device can be made lighter, the light buoy 1 can be made compact, and the mooring can be made bearable to the waves securely, with a good durability and an economy.
