Hello,
sorry, but I do not know what "needlespar" means.( my translation program neither )
The masts are made from aluminium, 190 mm at the bottom, 70mm at the top.
Wallthickness is 4mm at the bottom and 6mm at the top.
The aluminium is eloxated.
And yes - the sails are flat with standart alu - battens......
Riks
A problem could be, that the boat is in Sardegna at the moment......
but also a nice trip through france .... :-)
