R-43 Command Bridge By Ranger Tugs The R-43 Command Bridge is the largest vessel Ranger Tugs manufactures at the moment and this is the model we are discussing today. The company does however make smaller vessels all the way down to the R-23. There are quite a few models between the R-23 and R-43 CB. The R-25, R-27, R-29S, R-29 CB, R-31S, R-31 CB and the R-43S are those models. From the R-29 and larger essentially there is a sportier version and a command bridge version in each size.
