Kong, Iran - Workers clean a fiberglass Lenj as a part of its yearly maintenance plan. Maintenance costs take a heavy toll on Lenj owners who are already struggling with diminishing market as cargo ships are taking over a big part of the market. Many wooden Lenj construction workshops are being transformed into repair shops for older Lenjs as demand for new wooden Lenjs is giving its place to fiberglass ones. Currently, most of the Lenjs are used for fishing or exporting bulk material to nearby countries such as UAE.
