A traditional Iranian Lenj boat being repaired in the Gouran boatyard. Holes in the hull are filled with cooton wadding and the ship given a coat of paint. Gouran is the last shipyard where they still make and maintain traditional Lenj boats from wood. Typically they are now made from fibreglass. They are built to carry cargo, sailing the Persian Gulf, trading between Iran, Oman and Dubai. They carry fruits and vegetables, fish, electonics, textiles, livestock and sometimes for smuggling.In 2011 Lenj boat building was listed by UNESCO as an endangered cultural heritage.
