In
general the greatest impacts experienced by high speed
boats are in the vertical direction. These are generally found
to be up to 15 – 20 g but in some conditions can be even
higher. An example of an extreme vertical impact experienced
by Rigid Inflatable Boat (RIB) is shown below.
This is the type of event which can cause acute injuries to the crew, and
result in chronic injuries if the crews exposure is over an extended period
of time.
