Maroussi, Athens, Greece – May 6, 2021 – Euroseas Ltd. (NASDAQ: ESEA, the “Company” or “Euroseas”), an owner and operator of container vessels and provider of seaborne transportation for containerized cargoes, announced today a new time charter contract for its container vessel M/V “EM Hydra”. Specifically:

The new rate will commence between May 15, 2021 and May 25, 2021 when the vessel will be redelivered from its current charterer.
