Ferry Schedule from Neapoli to Diakofti

Hi,

I will be going to Kythera for a couple days in April and will be traveling from Monemvasia to Neapoli where we will taking a ferry to Diakofti.

Does anyone know the current ferry schedule from Neapoli to Diakofti for April?

The ferry times will determine where I go the rest of my time in Greece since I will be moving around a lot.

Thanks!

Peter
