印度回水船如何从货运船变身生态旅馆
In the backwaters of Kerala, southern India, a traditional boat called the kettuvallam is experiencing a remarkable second life. These vessels, once the workhorses of the region's intricate canal network, now serve as floating houseboats for tourists seeking a slow, green escape.
A kettuvallam is built entirely from jackfruit tree planks and coir rope — no nails are used. Skilled carpenters stitch the wooden planks together with coconut fiber, then seal the seams with a paste of cashew nut oil and cotton. The result is a sturdy, flexible hull that bends with the waves instead of breaking.
