You'd have to check with the ferry company before you travel as to whether they'll allow your hamster on board (don't see why not though - assuming it's caged !) If they do allow it - it will travel in the cargo hold along with the luggage anyway.
As for sea-sickness - It's unlikely the hamster will suffer from it, as they're pretty robust creatures. Assuming you get the OK to take it on-board - just don't feed it from the morning of the trip, so it's stomach will be empty.
no they don't…. if blood does come out that actually means they are sick.

They can, but it might make them sick. Hamsters are small, therefor they need very small food.
Not necessarily. It depends on how well your hamster is cared for.
Yes, your dog could get sick. You should talk to a vetrinarian.
yes but small animals get badly sick so they have to go ASAP or they will die.
