sorry if i offended paul - i did say i had a weird sense of humour
Though the practical side of the remark was correct, as someone just pointed out, lugging an enormous ship to the lake or even storing it would be the key factor, indeed at 11 foot the enterprise would be impractical and therefore would something in the range 1/200 be better. Hermes again would be better at a smaller scale, but you already produce a fine carrier and how easy is it to lug to a venue!
I still wonder what your thoughts on RFA's, though not glamourous, they do provide an essential service keeping the war vessels on station, the detail in one of these ships would be far more complex, or would that detract for the purpose of your enquiry?
