The Restoration of Thelma IV/Gladan, Flagship of Sweden’s Volunteer Motorboat Flotilla 1916–1918

Follow the Restoration of Thelma IV

This is the offshore motor cruiser that began its life as the flagship of Gothenburg’s, and later Sweden’s, Volunteer Motorboat Flotilla during World War I, serving between 1916 and 1918. She is also known by the names Gladan, Vipan, Intra, Valkyrian II, Valfrid, and Vinga.

The hull is essentially brand new, as much of the original structure was either rotten or corroded beyond repair. However, the boat retains its historic interior, bulkheads, original fittings, and sturdy teak floorboards. The interior is being restored to match the original design.

Once completed, Thelma IV will be offered for charter by Jaktrederiet AB, catering to small groups. The vision is to provide events and cruises in an environment featuring Honduran mahogany, mirror-like varnish, polished brass, velvet-upholstered sofas, and gleaming binnacles — recreating the experience as it was over

100 years ago.

There are very few large motor yachts remaining from the 1910s, regardless of designer. Among those attributed to the renowned designer CG Pettersson, we know of Thelma IV and Carla III. Every boat from this era is a unique historical artifact, handcrafted with one boat per blueprint.

It is particularly fascinating that so much of Thelma IV’s history has been uncovered, thanks to the descendants of previous owners. The boat was in near-total disrepair, requiring massive investments for restoration. Progress has been slow due to underfunding, as rebuilding such a large vessel from the ground up is highly

labor-intensive and, consequently, extremely costly.

When completed, Thelma IV will be among the few large antique motor yachts restored to near-original condition, capable of being operational for many years to come. For 50 years, the boat was used as a taxi between Gothenburg and Styrsö, proving her suitability for future charter operations.
