New high-resolution spectroscopy of the Algol-type binary R CMa is presented and reduced, allowing a re-analysis of this puzzling close pair. New radial velocity curves are in better agreement with the results of Glazunova, Yushchenko & Mrktichian, which revise upwards the relatively low masses of Tomkin. We find the following main parameters: M1= 1.67 +/- 0.08, M2= 0.22 +/- 0.07; R1= 1.78 +/- 0.03, R2= 1.22 +/- 0.07; L1= 8.2 +/- 0.2, L2= 0.49 +/- 0.01 (solar units); and photometric parallax 22 +/- 1 mas.
