In a significant number of collisions, we have found that most mariners do not reduce speed to avoid a collision.
In a significant number of collisions, we have found that most mariners do not reduce speed to avoid a collision. They are either in a hurry to attain sea speed after dropping the outbound pilot or reluctant to touch the telegraph to reduce the speed when navigating in areas with high traffic density. There could be many reasons for this reluctance, such as commercial pressures to maintain ETA, tides to catch, fear that engine would sustain damage, penalties on late arrival, and maintaining performance of the vessel in terms of speed-consumption.
Whatever the reasons, a reduction of speed does have benefits. It not only allows the mariner greater time to assess the situation but also in the unfortunate case of a collision the resulting damage would be a lot less severe to both the vessels. Also, hard helm orders without reducing speed could lead to large over-swings which can become difficult to control.
