Northern Ireland Newbie needing assistance

Hey everyone!!
Hadn't been in the water for years but went out bodyboarding on Sunday and it got me in the mood to keep it up so I went to my mates and lifted 2 old boards that the last tenant left in the sheds.
I'm not really sure about what exactly one of them is, one is a Bic 7'3" minimal and the other is a Bic longboard.
Both have had a few dings and knocks but the longboard has a ding with a crack in it but I'm not sure how that board is made to proceed with a repair. I'm hoping posting a pic will enable you guys to help me out.
here's the mini-mal

and here is the longboard
