First results for the triton binding energy obtained from the relativi
stic spectator or Gross equation are reported. The Dirac structure of
the nucleons is taken into account. Numerical results ars presented fo
r a family of realistic one-boson exchange models with off-shell scala
r couplings. It is shown that these off-shell couplings improve both t
he fits to the two-body data and the predictions for the binding energ
y.
