41.4knts, fully fueled(180ltrs) and 2 up. I think it is academic really as she will be seldom at wot.Torquey,quiet and gets on the plane quickly.
A great boat which,I have nothing but praise for.
I don't think you would be disapointed at all,I looked at a 585 but decided that the 6.4 was the better boat,
Good luck !
