I bet Marie G will be sensational, probably the fastest monohull sloop-rigged junk ever. The first test sail in F3 winds weren't enough to show her potensial, but she was still fast, over 5 kts. Handling and tiller balance was just right and above all she had this effortless way of moving. She didn't feel that fast until checking the GPS.
The 20mm carbon mast surely is lighter than our usual wooden poles so Marie G has a faster natural roll rate. That reduced weight and windage of the mast will of course be helpful when sailing close-hauled.
Marie G surely will turn heads wherever she shows up. Now with 55sqm in 8 batten panels the SA/disp will be over 27! A fine example of moderate hot-roding; MG is still a very well-behaved lady.
Good luck! Arne
