As far as Turkey
goes, I can give you some info..
For two successive years of chartering out of Turkey
, depending on the boat you choose, you can obviously get some discounts form the price
list. The total discount, my guess, cannot be more than 20-25 % off the list price
. To give you an idea an Athena 38 could come at around 1.900 €, A Belize 43
at 3.000 €..
You will be ollowed to sails
in Greek and Turkish waters but beyond that might be problematic.
This would make much more than 2 years of deppreciation on any boat + you can sail anywhere w/out restri ction. So, if you have the cash to buy a used boat
and accept the deppreciation, you would be much better off this way, compared to long term chartering.
If you need further help, pls send to me private note.
