Jeff Woodard Said he had absolute no issues at 175 lbs (79 kg) on his Taipan 4.9. Sounds like you are in the clear.

I think Jennifer weights about 140-155 lbs (65-70kg) and she has added a righting pole. Maybe she is lighter still, she looks kind off thin in the pictures.

An F16 at minimum mast tipweight would come require about 12 lbs (=10 kg) less to right so that one should be rightable by people weighting less than 60 kg.
