Environmental conservation and energy saving have become very important in recent years. Positive preventative method should be also taken in the marine transport. Sail equipped vessel is one of the countermeasures answering the request. However, present sailing-rig has following fundamental faults : (1) Difficulty of maneuvability in harbor (2) The dangers of dragging anchor for wind effect at anchoring In order to remove these defects, we develop an universal sailing-rig that allows each sail to move independently. The results of the experiment on the effect of the sailing-rig on ship are summarized as follows : (a) The manevability becomes easy as same as normal vessel. (b) Anchoring is improved and becomes safe. (c) Sailing performance is improved for a light breeze. (d) The cost of maintenance is decreased because of soft sail.
