RULE: In a strong breeze a submarine will attack from windward if possible. REASON: (a) The periscope moving with the wind and sea make very little commotion in the water. A periscope moving to windward will cause a large amount of spray even when moving at the slowest speed. (b) A lookout to windward is very much more difficult to maintain than one to leeward, especially if rain or snow accompanies the wind. MEANS TO AVOID SUBMARINE: It is advantageous to have a strong wind abaft the beam. Lookouts to windward should be increased and frequently relieved.

E) In zigzagging large changes of course are disadvantageous as by making such the danger area is increased and the time within the danger zone increased. htm (34 of 35)7/19/2006 21:38:17 Analysis of the Advantage of Speed and Changes of Course in Avoiding Attack by Submarine - ONI Pub. No. 30 from the limiting position. For speed of ship 12, and submerged speed of submarine, these times are, minimum 10 minutes, maximum 20 minutes. (g) That the changes of course must be sufficiently large to cause a material error in the calculations of the submarine's commander.

The most favorable wind conditions: (a) Breeze 3-4, the attack from windward. The most favorable sea conditions: (a) A light whitecapped sea. To avoid giving the submarines these favorable conditions a ship should: (a) Avoid steaming on such a course that the bearing of the sun will lie within the danger angle; (b) when possible, steam with the sea; (c) at twilight, steam toward the brightest part of the horizon. --- 31 --- 81. Considering all the points covered in the discussion of speed, changes of course, and weather and visibility conditions, the following conclusions are reached: (a) Every endeavor should be made to increase the speed of all vessels when passing through the danger zone.
