An ocean towing bridle whose legs are of equal length, but too short, may __________.
β’ Towing bridle geometry β how leg length affects the angle at the towing point and over the chocks/fairleads β’ Load distribution in a bridle β when legs are truly equal and symmetrically led, how is load usually shared? β’ Effect of short vs. long bridles on angle of pull, chafe, and tendency to lift out of chocks or fairleads
β’ If both legs are exactly the same length and led symmetrically, what normally happens to the load on each leg? β’ What happens to the angle of each leg and the way it rides in the chocks/fairleads if the legs are made very short but still equal? β’ Which listed problem is most directly caused by the length of the bridle legs, rather than by poor adjustment or asymmetry?
β’ Verify which option is a direct consequence of short but equal-length legs, not of unequal leg length or poor rigging β’ Focus on how steep lead angle and vertical component of the towline force would affect the legs in the chocks/fairleads β’ Eliminate any choice that describes a condition that would normally require unequal leg length or misalignment to occur
