Not really. Slide rafts would be deployed after the aircraft ditches, what we call ditching in aviation. It is done by the pilots with the clear intention to do so.
In ideal conditions aircraft floats for a while and cabin crew would open doors in armed mode. Slide rafts are deployed automatically when doors are opened in armed mode. Cabin crew would evacuate the pax on rafts, disconnect the rafts and apply sop's to survive for as long as possible and signal when activity is observed in the nearby area.
A B777 raft is large, it can fit up to 80 pax. It does have an orange canopy.....if the sea was rough it would be very hard for a raft to be afloat after 14 days, but you never know.
