These are 2 questions to ask yourself before starting to spend money
in something that will be a great disappointment, not to say a huge amount of money
Turkey "Gulets" (I guess this is what you are thinking about, nice wooden boat...to watch) looks good, and sound very cheap
But, these boats are usually manufactured for the local charter
market, bringing non sailor tourist at sea for few days, under very nice sea and weather
condition (if not, they stay at mooring
waiting on weather), jumping from one bay to another, for bathing and relaxing most of the cruise
They have masts, but not every time sails
...and if so, they are not equiped properly to use these sails
most of the time, they just want to "look like" old sailboats, on a romantic fashion, once again having their specific market in mind.
Of course, there are exceptions, with proper rigging
, sailclothing and decent construction, but the prices are not anymore attractive in such case.
I would strongly advise you, as you are in the "Viking land", to try to sail as much as possible locally, to meet as much sailing people as you can in Norway
, that will probably very helpfull in your search and analysis.
I noted that Norway (been there several time, for the job) is one of these countries that has a marina, or an harbour, in most of the cities alongside the coast and that sailing is a very popular activity.
Actually this is one of the best place to sail and get some advice.
Another way to help decision, is to choose a boat that is made with a material you are the most familiar with, this to help you in maintenance
, servicing and repair...quiet important for a long cruise
