$10k a month too rich for me

But I don't think outrageous - folk gotta remember that not only
renting ready to go, but some support (and understanding!) and the opportunity to shortcut (or omit?!) a chunk of
learning curve, which all costs time and
money - even if most of us don't count that in £ notes........and is spread over many years.
In straight cash terms could even argue that (for someone new to the boat thing) could even turn out as saving
money 
if later
buying a vessel of that size - easy enough to lose 10% on a boat by
buying badly........especially if then re-selling. After 6 months or a year onboard would have a pretty good idea of what
they needed.
I would also say there is some value from a large degree of certainty on costs for "only" a year (longgg
Charter, but very short to own / re-sell a boat)...........and avoiding the aggravation factor of buying, maintaining and then selling abroad / at a distance - not to be discounted that one.
LOL - so long to finish the post that the thread got moved back!...........oh well, it's in my ignore section now.
