Bruosen is one of the few river harbours in the county. As landing place for the churchgoers, this place and the boatshed environment follow a tradition that goes back to the Middle Ages, but the country store of today is much younger.
Furthest north in the island community Rongevær, at the entrance to Fensfjorden, lies Krossøy. Belonging to the farm are the islands of Krossøy, Husøy, Kårøy, Lyngkjerringa, Søre Kjerringa, Rotøy and Kuhovet. All of them have been inhabited. On Krossøy itself today there are four holdings. The marine use environment here is one of the best preserved along the West Norwegian coast.
The fishnet shed at Notaholmen stands as a reminder of the days when people used to row out on the fjord to set their nets. On Notaholmen the nets were dried, repaired and tanned. And it was a great advantage to store them in a place inaccessible for rats and mice.
Tthe Otterstad farms lie in the innermost part of Mofjorden, on the northwest side of the river. The row of stave-built boatsheds that belong to the farm were probably constructed a little after the middle of the 1800s. Both here and on the Mo side, the boatsheds were important storage places at the seashore; wood and other farm products intended for the town; corn and merchandise in return.
