Recommendation for antifoul, sealant and filler?

I have an Orkney Fastliner. Boat sits in the water all year round.It cruises at about 13 knots.
I have it at the house for maintenance a the moment.
I've sanded the hull and its ready for filling (keel band came away leaving screw holes to be filled before I fit a new one), sealing and antifouling.
Is there a particular filler, sealant, antifoul that you would recomend?

Thanks
Colm
