The main disadvantage to cold molded here in the US is of course labor, plus
the higher cost of epoxy over polyester resins. A disadvantage in Turkey may
be the resins. Here I am at a loss, not knowing what the cost would be
there. I do know that what we expect to find here may well not be found
there. 

A good question, in regard to Turkey, would be the experience of cold molded
boat builders themselves. Is this method commonly used in Turkey, or if not,
the lower cost of labour might be offset by the learning curve if the yard
has not built in cold molded.

One nice aspect of cold molded, is the lack of, or near lack of frames, thus
increasing interior space.

I have worked on Dutch built steel boats in this range, and have been very
impressed with the fairness achieved without fairing compounds heavily
applied. So if in the Netherlands steel would be best.

I am assuming we are talking about a trawler design, and this can be
something new to even experienced cold molded builders that are accustomed
to building very light racing craft. For a trawler I would look for a yard
that builds work boats, and is experienced with cold molding. If such a yard
is not found you may well be best off with the type of construction the yard
knows best.
