We investigate the category of U (h)-free g-modules. Using a functor from this category to the category of coherent families, we show that U (h)-free modules only can exist when g is of type A or C. We then proceed to classify isomorphism classes of U (h)-free modules of rank 1 in type C, which includes an explicit construction of new simple sp (2 n)-modules. The classification is then extended to higher ranks via translation functors.
