Christ and hunter man!, First dont act so belligerent,.
A corvette may well be a Kilometer in length, to be honest i dont know, care, not that you spelt length correctly in the first place, What am i meant to do, guess what you mean to say, use my non-exisistant psychic powers to bridge the gap between myself and frickin romania to comprehend you lacklustre grasp of english? second you didnt say i want a ship precisely 800M in length, you said about 800m in length, Now in my eys a Corvett is the closest to that size , Dont qoute me, I dont know!
Thirdly, The Iceni, Can already do what you Say its cot non-slash beams as well, I just didnt mention it cos it contradicts your size laws.. Alphaone, grammar... all i have to say grammar.
