Hehe, like your aspirations
Seriously though, the bigger it is the greater are the running costs. Unless you've a pretty inexhaustable supply of money, the extra stress brought on by a larger vessel is seriously offputting for me. Mooring fees, AF fees, rigging, sails, EVERYTHING is exponentially more expensive on a larger boat.
And it's not as if this is an investment hobby either. The money just disappears! Forever!
