is my longboard fit to use

Hi i have been surfing for a year (well falling of alot), i currently surf a 7,6 minimal/ fun board, it was given to me so know choice it prob a bit small and rocks like crazy. I have been given a long board which i think is the type of surfing i want to do.
its a Town and Country 9ft Long board it prob 10 years plus old it has a load of dings which i have fixed with resin so its water tight. i took it out once but the waves were huge 6ft+ which i now know was a silly idea and ended up with it smacking me i the chest. it felt really hevy to paddle and got paulled away by every wave. my mate who i surfed with said it felt hevy to lift and might have water retention. to me it does feel hevy but it is a big board and is old so is glassy and fat.
can any one advise me of how i know weather its worth keep trying it or weather i should bin it off. i had bought the board of a mate (non surfer) but got a refund and kept the board
if it is a reck then im going to buy a proper long board or magic carpet so would welcome advice on that to im 6'2 and 16.6 stone, i have no desire at all to do tricks all i want is to ride in on waves and have fun any advice wwelcomed.
weather it helps or not i surf bantham/ Bigbury on south coast and newquay when i can
thanks ali
