We left Thailand
after the Global Tsunami and we experienced three debris fields as we sailed across the Indian ocean
several weeks after the tsunami.
The first debris field was about 80-90 miles off the coast of Thailand
. That was mostly small stuff and not really a problem for a yacht to navigate through.
The second debris field was around the Andaman Islands that belong to India
. The debris was larger with gas bottles and palm trees floating in the water
The third debris fields was south of Sri Lanka, and that was the big stuff. 100 foot trees with limbs and giant root balls. We had to go hove to at night so that we didn't collide with the large debris. Some yachts sailed through the debris at night and sailed right over trees in the dark, costing one yacht a bent self-steering unit. It took a couple of days to get through all of that debris.
The scariest debris reported in the media was explosive mines that reportedly had been used to mine the harbors in the war in Sri Lanka. Reports said that the tsunami had washed some of them out to sea. That was a bit of a worry, but as far as I know, no mines showed up anywhere near the yachts crossing the Indian Ocean
