Are they made of plastic or bronze? If they're plastic there is a good likely hood that they will need replacement and if they are bronze, and seized shut, they will most likely also need replacement.
Seacocks should be closed every time you leave the boat.
This does two things:
#1 Regular "exercise" prevents the valves from sticking as you have discovered.
#2 Prevents your boat from sinking if a hose, clamp, water pump seal, strainer etc. etc. should fail and begin leaking.
P.S. The hammer won't do much, except cause further damage, especially if you're suffering from galvanic corrosion. Banging on any seacock is not necessarily a good idea..
