All ferry boat departures in Greece are subject to the Beaufort scale of wind strength. The Greeks pronounce Beaufort as 'Bofor' or 'Boforia' and most of them never heard of Beaufort but they all know 'Bofor'. On land they measure by kilometers but afloat by nautical miles so confusion can arise. Anyway, if the wind goes over 8 on the Beaufort Scale an 'Apa-go-ref-ti-KO' or 'Forbidding' is issued and all boats are not allow to leave port. However some smaller boats and especially catamarans are less stable and forbidden to leave port at lower levels of Beaufort strength as well.

The British Navy's greatest hydrographer and map-maker was actually an Irishman originally from Navan Co. Meath. Born in 1774 Francis Beaufort is best remembered as the originator of the Beaufort Scale which classifies the velocity and force of winds at sea.
