OK some people who can do it properly and have done excellent repairs for us!
David Boyd Imperial Surfboards OG Excellent work.
Strapper Surf Torquay ask for Rich they may or may not want to do it!
Dean Snow LSD Sea Breeze PM him. Dean has fixed lots of broken boards most almost as good as new.
These guys can work miracles but wont be cheap!
Me thinks might be better to get a new one

Put the board upright broken ends down leaning on a towel ASAP to draw the water out and change the towels until no more water comes out!
Disc: I have an assocaiation with all these people because I surf with them buy thier products / boards and true love the quality of thier work and service.
