I have seen already more pictures but most from landside. When you decided to go your holidays on Zakynthos I can recommend to make a day trip by boat charter to the shipwreck on the Bay of Agios Georgios. On the way there you see already beautiful coast etc.

Very interesting old ship wreck stranded there. Off season is the best time. The water was so clear that I thought that there was approx 40 cm water when I jumped of the boat...........

Unfortunately it came to my shoulders.
Result spoiled small (back up) camera and a handphone. Luckily the rest just saved :-)
Enjoy!
