We present the discovery of three transiting planets from the WASP survey, two hot-Jupiters: WASP-177 b (similar to 0.5 M-Jup, similar to 1.6 R-Jup) in a 3.07-d orbit of a V = 12.6 K2 star, WASP-183 b (similar to 0.5 M-Jup, similar to 1.5 R-Jup) in a 4.11-d orbit of a V = 12.8 G9/K0 star; and one hot-Saturn planet WASP-181 b (similar to 0.3 M-Jup, similar to 1.2 R-Jup) in a 4.52-d orbit of a V = 12.9 G2 star. Each planet is close to the upper bound of mass-radius space and has a scaled semimajor axis, a/R-*, between 9.6 and 12.1. These lie in the transition between systems that tend to be in orbits that are well aligned with their host-star's spin and those that show a higher dispersion.
