Second board recommendations

Hey guys
I'm a relative beginner, started surfing a year ago but only get out once, twice a month at the moment. I've got a longboard and during the UK winter, I sometimes have to not go because the surf is bigger than what I fancy tackling on my longboard, so can you recommend a second board for when it's bigger?
I guess the obvious choice is a minimal but I don't think it would offer much difference to my longboard. At my height (6'1) and weight (80kg), I think I'd need a long mini-mal anyway and the point is to make it easier to get out back and to have more rocker to help dropping in on those bigger waves. So I was thinking more of a 'fun board' something a bit shorter but with lots of volume still as I'm quite a big lad and still learning after all. Am I going to right sort of direction? Any help appreciated!
