With a sample of approximately 89\ifmmode×\else\texttimes\fi106 BB pairs collected with the BABAR detector, we perform a search for B meson decays into pairs of charmless vector mesons (\ensuremathφ, \ensuremathρ, and K*). We measure the branching fractions, determine the degree of longitudinal polarization, and search for CP violation asymmetries in the processes B+\ensuremath→\ensuremathφK*+, B0\ensuremath→\ensuremathφK*0, B+\ensuremath→\ensuremathρ0K*+, and B+\ensuremath→\ensuremathρ0\ensuremathρ+. We also set an upper limit on the branching fraction for the decay B0\ensuremath→\ensuremathρ0\ensuremathρ0.
