Hi Paul, I think you have hull
#10 of the 49's. I have #14, talking to the builder
at Soubise he said he built about 26 all up, I could be wrong as there was a bit of a language barrier. He has just launched the last 49 and is retiring from boat
Not sure about the construction, my sales documents stated Polyester when I have read they were Vinylester with Kevlar reinforcing as was Giffi, I think he may have made them to spec.
A pretty quick and comfortable boat
anyway, I have only sailed from France
and often saw low teens, sometimes with just a headsail up as I need to replace the lashings and do other maintenance
to the Rig.
Apologies for the drift as they say.
