Can someone advise me on my maths?

[Grant Midsummernight]

I am looking to set up a small non-profit organisation to run shares in a charter boat based in the Mediterranean - Has anyone done the same sort of thing - and will it make as much profit for the owners as I think it might - I have put my figures on<br /><br /> http://communities.msn.co.uk/ChartershareLtd/_whatsnew.msnw <br /><br />Could people advise if they think they are way off or reasonable.
