Via this link you can register:

All passengers in same cabin need to register together as one group. Therefore you can't register or pay for just one person (excluding cabins for one person). You need to pay the cabin reservation at the same time with your registration. You need a finnish bank account in Sampopankki, Osuuspankki, Nordea, or Paikallisosuuspankki to make the payment via internet. If you don't have a finnish bank account, contact apua(a)lemmenlautta.fi.

You need the following information about all passengers for registration:
- First name and last name
- Date of birth (date, month, year)
- Nationality
- Cabin class
- Chosen meals
- Other items, such as VIP or Pool Party tickets

Please note, that your email can be given out for informing joint transportation to cruise.

Please note, that you can't reserve a cruise without choosing a meal. Meal prices are higher when purchased from the boat.
