for your weight 111 liters is NOT a lot
you want to get back to where you started your launch - even if the wind drops ....
your sails are also really close in size - how old are they ??
a 7.0 for your weight is good in about 16 knots - let's say to 20 - i call those mid winds
that is no issue for a 121 liter board where the 7.x falls right in the middle of the range
my ideas are NOT based on experience with a Futura and as such suggest a Futura expert give their perspective ...
welcome back to my favourite sport :-)
