Nah, not a numbskull.
I don't know what size boat you have, but a rating of 180 is not necessarily strictly a cruiser. However, nowadays, with the proliferation of sport boats and other designs that are geared much more toward racing, 180 is falling further back in the fleet than it used to say 15-20 years ago.
It may depend on where you race, too. If the local fleet is more middle of the road and comprised largely of 15-25 year old designs, you may fall nicely into their rating range. If it's a highly competitive, modern fleet you're racing in, you may be in the afterguard.
P.S. I like your avatar!
