I have a 770 and it can only be described as awesome. Fitted with the 250 Verado I can easily get it over 60 but more importantly with family on-board cruise at around 30 -35mph at 1lite/nm. Interestingly there is another sweet spot at just over 40mph which again i can get the boat to around 1 litre/nm.
Once you are moored or anchored the cockpit set-up is fantastic, very sociable. Build quality is excellent, storage particularly in the cavernous forward locker is brilliant (almost too big as you will carry far too much rubbish with you).
It turns heads where ever you go, so dont expect a quiet life !
if there is any negative its only in a following sea where you need some more cautious control of speed to wave height to to the fine bow section.
Mine is for sale by the way if interested, details on here, i do need it to go so would do a very good deal for a quick sale !!
