The crew of a small ro-ro have issued a call for help after the vessel suffered mechanical problems and developed a list in the Caribbean.

The seafarers and unspecified sources said the 940-lane-metre Indigo I (built 1990) is listing at 35 degrees, according to maritime news site Paraguay Fluvial & Logistica.

Maritime databases say the Panama-flag ship is controlled by Paraguay’s Independencia Shipping, which could not be immediately reached for comment.
