I have cruised around Turkey
(mainly Gocek / Fethiye and the nearby bays) on a mono (Dufour 385) this year and a cat (Lagoon 380) last year.
We went with a bigger group last year (6 of us) and went for the cat, this year it was just 3 of us, so went for a mono.
We did have the benefit of a local showing us around (I say local, an ex-pat who's been living there a few years).
What would I charter
if I went again (which I will)?
Either, it depends on who is coming and what I want to get out of the holiday.
If its for simply cruising around, very short passages and anchoring
up in random bays, then the cat. If I'm intending to sail longer passages then the mono (I prefer sailing in a mono, I feel its a more comfortable ride, whereas the cat wobbles everytime a motor
cruiser goes past at 25 knots)!
Also it would depend on how many people, a bigger group is far more compfortable in a cat. We managed to get births without booking in advance everywhere we went. Most places don't charge you, so long as you eat with them. The facilities in some (not all, some are very plush and have lovely showers/spas etc.) are basic, but still better than having to stick to the marine
toilets the whole time!
I've never been in July, but it will be HOT then, make sure you have fans at the very least!!
Feel free to ask anything else and I will try to help!
I should point out I am by no means a well travelled sailor, having only done coastal sailing/boating to date, so I may not be the best person to seek advice from, but hopefully that has been of some use :-)
