Curragh. In 1976 Tim Severin duplicated St. Brendans feat
of crossing the North Atlantic in a 36 foot boat similar in
construction to the legendary craft of the Irish saint. Historians,
like anthropologists, have rarely been small boat people.
So it would probably surprise them that Celtic voyages to the
New World were most likely carried out in the sewn-skin curraghs,
not in the larger, faster, and more manoeuvrable wooden planked
ships they used to battle Caesar. The small and slow curraghs
were able to ride required to cut through the waves. In heavy
seas this could mean capsizing, and when a heavy boat capsizes
it sinks. The curraghs would not only be less likely to capsize
but if they did they would not sink.
