G'day Folks,
Can you help a newbie out?

For years I have said "geez I'd like to give surfing a try" but either my health or work or something else has stopped me from actually having a go.
Well, I have just turned 50 and my darling Wife has forced me to actually get in and have a go by buying me a Mal.
Yeah I know, I should have taken some lessons and hired some different boards before buying one but what can I do . . . Wifey just wants to make me happy.
Can someone tell me what I have here 'cause I know 3 fifths of 5 eighths of nothing about boards.
Its a Nigel Beckham; Black Lable with these dimensions written on it:
9'2" X 14 3/4 X 23" X 19 1/2" X 2 7/8"
I'm 5'9" and around 110kg, am I going to be able to ride this thing?

Any help greatfully accepted
Cheers
Fredo
