There is no ferry between these groups. A boat cannot take you from Bali to the Gulf of Thailand, so the map keeps them apart rather than drawing one network that implies a crossing exists.

Markers sit on the pier a crossing actually uses, taken from OpenStreetMap rather than estimated from the place name. Several destinations have more than one pier, and where that is true the marker says which one it marks and how far the others are.
