Answer 1

Take a ferry. They go everywhere in the Med.

Answer 2

Everyday except Wednesdays there  is a hydrofoil from Piraeus (I assumed as you didn't say where from) to Katapola,  at 07:00 arrives at Katapola at 11:30 in the morning and the cost is (now) E 43.50.   It is Hellenc Seaways and you can book it online
