Abstract
Following the experiments using cargo three islander model these are reported in Part 1 & 2, we carried out some experiments on mooring and riding at single anchor using model ships of Aft Engine Aft Bridge Type Vessel and Oil Tanker. The results of experiments have shown followings: 1 Aft Engine Aft Bridge Type Vessel can ride out gale easily in comparison with othir type vessels, as her yawing is very small. She will be able to ride out gale at single anchar when full loaded. In case of mooring, yawing can be checked with open hawse at angle of 45°. 2 Oil Tankers will be able to ride out gale even when at single, anchor if full loaded. As ther eason they receive less wind pressure and immerse deeper in comparison with three islanders. In case of mooring, yawing can be checked with open hawse at angle of 60°like as three islanders.
