  We performed a detailed spectroscopic study of the SB2 system HD 60803 based
on high-resolution spectra obtained with the different spectrographs. The
analysis was done with two independent methods: a) the direct modelling of the
observed binary spectrum by a sum of synthetic spectra varying a set of free
parameters and minimizing a difference between the observed and theoretical
spectra; b) spectrum disentangling and an independent modelling of the
individual components. Being applied to binary spectra from different
spectrographs both methods converge to a consistent solution for the
fundamental parameters of the HD 60803 components: $T_{\rm eff}$=6055$\pm$70 K,
$\log{g}$=4.08$\pm$0.12, $\zeta_{\rm RT}$=1.45$\pm$0.18 km s$^{-1}$,
[M/H]=0.03$\pm$0.06 (primary), and $T_{\rm eff}$=6069$\pm$70 K,
$\log{g}$=4.14$\pm$0.09, $\zeta_{\rm RT}$=1.48$\pm$0.18 km s$^{-1}$,
[M/H]=0.03$\pm$0.06 (secondary). Differential abundance analysis of the
components did not reveal any significant difference in their chemical
composition. Besides Li both components have solar atmospheric abundances. Li
abundance exceeds the solar one by $\sim$2 dex, but it agrees with Li abundance
in main-sequence late F-stars. Relative-to-solar abundances in both components
slightly correlate with the condensation temperature the same way as was found
in the solar analogs with/without detected giant planets. The estimated age of
the system is 5.5$\pm$0.5 Gyr.
