pike rods for beach fishing?

Hi all, just wondering if I could use my pike rods for beach fishing? They
are a two piece 13ft 3lb test curve rod, with six large bore Fuji rings. I
have used half mackerel baits and punched them out a good distance when pike
fishing, but I have never been sea fishing before and I am not sure if these
would be up to the job. Do I need to buy a more suitable rod? I'll be
fishing around the Norfolk coast if that is of any help. The rods should
handle line to around 18lb+ if I remember the test curve formula.(which I
don't!!) not sure about casting weight, i.e. max.lead weight, but if they
handle casting a half mackerel at a good distance.......Any advice would be
very much appreciated. Cheers, Lee
