these are really quite large and hire out for 8 to 10 days for up to 6 or 8 couples from $20,000.00 to 100,000.00 depending of size and luxury. they are everywhere. They have a race in late October off Bodrum - apparently it's very competitive and funny s they really are not very manoeuvrable under sail. (Rather a lot of Raki involved too) So far we have only seen them under motor - perhaps that's why.
