EXPERIMENTAL INVESTIGATIONS OF 37
ACCELERATIONS AND VIBRATIONS ON VEHICLES AND BOATS

necessary to weight axes and show that it is not necessary to weight certain axes more than
others. In further work, the experiments should be repeated in higher sea states. Also different
type of boats can be used. The magnitudes of impacts reported in this work are lower than those
in other works. However, it is not clear how their data were collected and analysed, and
therefore it is not easy to gauge the accuracy of their results. It is reasonable to assume though
that the impacts encountered would have been larger due to the higher sea states. It is also
possible to evaluate an impact formula for RIB high speed marine crafts by using the parametric
sea tests. It is also intended to apply the algorithms and analysis reported here to a series of
model tank test experiments involving a variety of hull forms. From these experiments it should
be possible to determine each hull’s VDV and motion characteristics in a variety of sea
conditions, which could prove useful to naval architects designing RIBs that exhibit better
performance regarding the new legislation.
