I was doing to say a boat rod, they are often designed like this. Most people use beach casting rods on piers, the 12ft gives plenty of room for bite detection with about 6ft of it sticking over the railing when propped up and the top sections are not so stiff. And fish are mostly a lot smaller than what you might catch in a boat. Boat rods are designed to pump big fish up from a long way down off the bottom and are normally short because its easier and safer, wielding a long rod around in a boat is not practical.
However, nothing wrong with using this rod, plenty of people do, just a bit less than ideal on a pier, give it a go. Just a medium sized reel, a 20lb line or 15lb maybe, a flowing trace, lug worm, fish or squid strips on the hook. You can cast with it just not as far, maybe 30/40 yards whereas you can go 100yds plus with a proper beach caster. Some piers this is necessary to hit some known spot but plenty of fish down below piers; often over looked by regulars who often just like to show off with their casting prowess.. Occasionally a big conger lay around piers although rare or a big bass might come along and you might be grateful for the rod, I have seen good fish lost on piers because they are under gunned for such fish. However, the general mill are flatties, mackerel, pouting, small or medium sized cod, whiting etc.
Its an idea if your dropping down from a pier to get there at low tide and observe any snags if you can or ask some anglers on the pier if its snag free where you intend to fish, regulars will know of the snags and are usually helpful.
It can be a very pleasant day on a pier, have a go.
