Just thought I would give this a mention although its probably not the boat you mention.
When we were in Marmaris this year we were offered a free "midnight" cruise when we booked another 2 trips. At the time we thought it wouldnt be up too much as nothing is really free. However. we were very pleasantly surprised. We were picked up from our apartments, taken right down the beachfront and shown to our boat. We had a very nice free meal on board but you had to pay for drinks (not overpriced). Although it is called a midnight cruise I am sure we were picked up around 7.30pm ish. First of all we sailed along Icmeler way then came back and moored whilst we ate then went further along to the Marmaris marina. At the end of the evening we were transported back to our apartments.
I would have to think really hard though to remember the name of the boat. We booked the trips
in Armutulan from a guy called Jack Daniels, opposite Red Rose restaurant
