I think you will find that about 20/25 years ago French boats changed to
using LOA in their model number previously it was i think LOD. So to compete in
a market where every last inch was measured to turn a 40 footer into a 43
footer the French boat manufacturers started to play the same game. Failing to
do this would have made their boats look both expensive and small. One boat
i know quite well a Beneteau First 38 was in fact 41 foot long.
