Aluminium hull, aluminium trailer frame – you need a roller that won't chew into the metal. This Viking 91112 blue hard-nylon wobble roller is built for exactly that pairing. 4in x 4in face, 19mm bore. The nylon compound stays firm under load and won't leave the soft-rubber smears you get from cheaper options. Pop it on your cradle or trailer axle and the boat tracks straight without that annoying side-to-side wobble
