Anna Maria Catharina Magnus

Catharina's husband Johannes appears to have started the shipbuilding at Haagenvik. The Haagenvik property was situated on the fjord, in an ideal place to build and launch large boats. He took over the ownership of the property from his father-in-law Frederick Stockfleth von Krogh. Frederick and his wife had 7 daughters and no son to inherit the estate. At that time it was not possible for a female to inherit the assets of one's father. Since Catharina was the oldest of his daughters, her husband became the legal successor. Johannes came from a family rich in sailing and shipbuilding tradition, and Haagenvik, with its direct access to the fjørd, was a perfect place to build and launch ships.

Thus the old officer farm became property of the Magnus family. The shipyard delivered its first vessel in 1852. At the time, Johannes Magnus lived in Hogganvik. He was a strong fellow from what is told about him. He was 6 feet and 6 inches tall. One time, some lumber had been ordered from Dokskar, and it was brought to Hogganvik as a raft. Johannes Magnus was not satisfied with the lumber. "What kind of material is it that you are bringing? It is nothing but garbage" he said with a thundering voice. The man from Dokskar got upset and said that if Johannes Magnus could carry the largest piece of timber on his shoulders, he would give him the whole shipment for free. Magnus took the largest timber on his shoulders and carried it all the way from the docks to the barn, where he threw it on the ground. The timber remained at this spot as a reminder of Johannes' strength. Johannes Magnus had several sons and the two first born, Frederik and Morten, became the great shipbuilders at Haagenvik.
