A change of the guard takes place in 1925, when son Geert Wagenborg and son-in-law Lourens Vuursteen join the company. Wagenborg flourishes under the new management, the number of charters rises and the arrival of maritime engines make it possible to maintain schedules more easily. Finding cargo is a time-consuming business. But the solution is found in the form of a broker who arranges the cargo and shore matters for the skipper.
Around this time the commercial ambitions of Lourens Vuursteen come into their own when the first motor vessel, "Fivel" is purchased in 1927.
