Not sure which avon SIB you have. Some of the avon's I have used in the past have been extremely capable in the surf, others seem quite flexible and seem to flop over the wave (almost to the point that you think that they may fold in half!), still good fun though.
I guess you will have to find out the capabilities for yourself, bit by bit. I would reitterate that wind is often what catches people out. SIBs tend to be very stern heavy (particularly when singlehanded) and so it is possible to get the bow very high in the air from only the smallest takeoff into a head wind. 30kts into a f4 wind gives more than enough lift to scare you silly and seveley bruise your crew on landing (ride is far softer for the helm). Make sure that engine is screwed on well!
Bow ballast (drybags filled with water are good) and engine trimming help reduce this and give you a smoother, faster ride.
I have most fun on days when wind is blowing against the prevailing wave direction (not often I admit), least fun in a wind driven short chop.
