Hi Marino,
You got the latest version of mono-hull_speed_figureV17.xls
You can also download it from: http://members.chello.nl/~t.iwema/Plans.html
Your boat is a fast boat when sailed at wind steeds up to force 3.
Even at lower wind speeds you can reach your max. speed (wave speed).
At force 3 you have to make the sail more flat to be able to sail the boat.
If I’m wrong please tell me.
I put our conversation on the internet so more people can use the information.
Regards,
Hugo
