Hello, yes this is standard procedure because Greek authorities need to know who is aboard for search & rescue / covid reasons. This is not related to your cruise operator ; this is required every time you board a ship. Have a nice journey!

The swimming was optional on the trip I went on it was a bit too cold for me to get in the water a number of people did though. there was lots of food and drink included on the boat

i would suggest to book it on advance

This was absolutely the time spent on the water. We were picked up at 2:10 for a 3 pm departure, arrived back at the marina shortly after 9 pm and were back at the hotel around 10 pm. This was one of my favourite things to do during 3 weeks in Greece.

The amount of people able to reserve is the difference. I don’t remember the difference in people on each boat. But I would go with the one that carries the smaller amount.

Not sure. They have several boats and I’m not sure if they all give same service. You should be able to ask them. Super friendly!!

Congratulations! We would advise that you have your doctor's approval for the participation of any tours. We have had many pregnant women on board, there is no danger but each ladies circumstances while pregnant are different. I would assume that if you are okay to travel, it would be fine to take a catamaran tour. If you do decide to book a tour, please make a note on the reservation, that you are pregnant. Thank you.

We went in Oct but needed a long sleeve shirt and pants and jacket for after our swim. It was very cool on the way back in.

Each of the boats hold different numbers of people. I went on the high speed boat (highly recommend) and the Max was 10. We had 8 and went in September. The other boat that says it holds 40, gets packed in. Would suggest to pay more and go on a boat with less people.

No difference - loved the Triton more though.
