Seatours has two ships they operate. One is the big ferry between Snæfellsnes and Westfjords with a stop in Flatey. The other is a fast catamaran which tours the different islands in Breiðafjörður.
The ferry between Stykkishólmur, Snæfellsnes, and Brjánslækur, Westfjords shortens the drive to the Westfjords considerably. It is also a wonderful cruise through the huge bay Breiðafjörður. It makes a short stopover in Flatey too. A lovely little island with a small picturesque village.
The catamaran offers tours around the small islands to watch puffins and wildlife. One of the more popular tours is the Viking Sushi Adventure Voyage where you get to taste seafood straight from the ocean.
