This table is intended to gathers in all the ships and boats that do not qualify for one of the other tables in this section. The cut-off values of 50 feet and 100 GT used in this table are a bit arbitrary - they are designed to allow the table to focus on those vessels built in traditional shipyards and boatyards and to reflect the reality that the smaller boats are almost impossible to track. The result is a table of only 41 vessels, of which 31 are dredges. If anyone has any corrections or additions to this table, please send them to timcolton@aol.com
