StealthGas chief executive Harry Vafias is seeing LPG carrier charterers taking increased term cover as tonnage tightness grows.

Talking on a conference call with analysts, the Greek owner's boss said that in the third quarter, despite customary seasonal softness, rates had improved, mostly towards the end of the three months.

"Looking at the small LPG carrier trade west of Suez, the spot market experienced the usual seasonal downturn during the summer months, forcing owners to experience idle time between voyages," added Vafias.
