There have been some sea disasters at times on the ships loaded with Lauan Wood. The authors have carried out model experiments and conducted experiments on ships at sea. These results had been reported in the Journal of this Society. Recently, an additional investigation has been made on the actual conditions of the ships on the service of Phillipine Route. The present paper reports the results of above investigation, the summary of which are as follows ; (1) It is reasonable that the value of GM of ships loaded with Lauan Wood on deck is 30cm or more over through the voyage. (2) It should not be ballasted by sea water for compensating GM in the ship's hold which is loaded with Lauan Wood. (3) It can be said to be good condition that Lauan Wood on deck is loaded as near the midship portion as possible. (4) The mean draft of ship should not be over the summer full load draft by regulation. (5) The fastening of wood on deck should be made by suitable lashing wires or chains not only transversely but also longitudinaly. (6) It is desirable to enlarge Freeing Ports and Scuppers on deck.
