The study concentrated on analysis of wake from conventional ferries in the Tallinn Bay area, in particular the ferries Star and Superstar (described in [17]), which are known to be responsible for some of the largest wave loads on the coast [19].
3c,d) corresponds to the ferry Star, arriving at about 900 s, and another wake from an unknown ship arriving at 1200 s.
The wake from the Star (1 July, 10:30) probably provided more reliable results than the wake from the Superstar (2 July, 07:30), as the former was recorded at a time when there were less small-scale local variations associated with wind-generated waves.
The wake from the Superstar shows a similar reduction in divergent waves, whereas the contribution from the transverse waves was conserved from TPL-1 to TPL-2 (at about 3.9 x [10.sup.3] J x s/[m.sup.2]).
