Transverse mass spectra for D mesons are calculated in 1+1-dimensional hydrodynamics using different equations of state. Parameters of the simulations were tuned to describe proton spectra in heavy-ion collisions at RHIC. The assumption that the initial distribution of charm follows a scaling of binary collisions different from the bulk matter leads to significantly smaller effective slopes and mean pT value of the D-meson spectra, similar to the effect of a possible higher freeze-out temperature. This has to be taken into account in the interpretation of such spectra in the context of hydrodynamical models
