The yacht was rescued off Kavaratti Island, Lakshadweep in early morning, the Coast Guard said in a statement.
The yacht, on its maiden voyage from Seychelles to Abu Dhabi, suffered total power failure on board and had been drifting on the Arabian Sea since August 2, it added.
This is the second such operation this monsoon. On June 17, the Indian Coast Guard saved three lives on board a yacht.
