The name ‘trehantiri’ comes from Byzantine Greek, “trohantiras” which means curved bow stem and signified “a fast ship that sails ”.
Trehantiri is significantly wide compared to its length and has a bow and stern that is made curved like the hull. The shape makes the boat very suitable for sailing. Shipwrecks have never been recorded and one of its major advantages is that it can sail no matter the weather conditions. For this reason, no alterations to the hull shape have been needed since the 17th century. The most important change that occurred, however, happened in the 1920s when sails were traded in for diesel engine.In the past few years the European Union has subsidized the burning of small wooden fishing boats and since 1991 about 10,500 traditional wooden boats, mostly of the trehantiri type, have been destroyed.Thus, the traditional Greek naval art faces the danger of dying out.

You can see this simple wooden shell boat design pretty all around old world, which deffinetely is the combination of easy to build, easy to sail, easy to maintain and very safe in the open sea.
This is not easy to maintain a wooden boat, believe me. You can find and buy one in a good price but you must have on mind that they need a lot of care such to remove the old varnish or paint, take care the woods, you must keep her moisture all the time, check her for any wear and tear, replace the old woods .But the more time you spend on caring for your boat the less time you will lose to breakages and breakdowns when you are using it.
