I too am looking to go to Greece and currently trying to research a charter company that is reliable. I'm interested in going this August but the price point may be too high. The lowest quote from Dream Yacht is $9 618,00 for & days on a Helia 44 with A/C .

I may try to go off the beaten path and use Saileo or Boatbookings. Guess it may be a higher risk/lower-cost option or eliminate the false security one has with a larger company.

If others know of other options to charter at a decent cost please share!!
