i know the rangers have a couple of redbays, the big 11m (??) one was lying at the door of the station out the water for whatever reason and the one with twins was lying in its usual place. it may have even been a single 115 on it actually.....never paid much attention.
it was a 7.2 i'm sure the badge said, never seen one that size. i thought they only had a 640 and then a 7.4, maybe an older design.
i don't think it was the rangers boat though, was in good condition, the ranger ones are pretty poor TBH.
