Blueprints for a concrete boat Concrete boat constructed by Walter Dowsey hauled out in Chicago The Namsenfjord. The oldest known ferrocement watercraft was a dinghy built by Joseph-Louis Lambot in Southern France in 1848. Lambot's boat was featured in the Exposition Universelle held in Paris in 1855.
Ferrocement or ferro-cement [1] is a system of construction using reinforced mortar [2] or plaster (lime or cement, sand, and water) applied over an "armature" of metal mesh, woven, expanded metal, or metal-fibers, and closely spaced thin steel rods such as rebar. The metal commonly used is iron or some type of steel, and the mesh is made with ...
As the hull thickness is typically 2.5 to 3 cms, ferrocement is unsuitable for boats less than about 15 metres LOA as there is a weight penalty; above that length there is no penalty. Properly plastered ferrocement boats have smooth hulls with fine lines, and amateur builders are advised to use professional plasterers to produce a smooth finish.
These were a type of concrete ship built with ferrocement. Steel shortages led the US military to order the construction of small fleets of ocean-going concrete barge and ships. Typical Displacement: 5,636 long tons (5,726 t), full load: 12,910 tons. Length:366 ft 4 in (111.66 m), beam: 54 ft (16 m), draft: 26 ft (7.9 m), crew 52 officers and men.
Early boats include the birch bark canoe, the animal hide-covered kayak [12] and coracle and the dugout canoe made from a single log. By the mid-19th century, some boats had been built with iron or steel frames but still planked in wood. In 1855 ferro-cement boat construction was patented by the French, who coined the name "ferciment". This is ...
The boat was proposed for building in ferro-cement construction at that time, but later changed to fiberglass, although wooden examples with caravel planking were also built. [ 11 ] The design is a recreational keelboat , built predominantly of fiberglass, with wood trim.

The ferrocement boat was launched into the river at high tide, but as the tide receded, the boat capsized and lay sideways in the mud, while a kerosene lamp broke inside and partially ruined the interior. [7] But the concrete and steel hull survived, and the boat began its voyage down the east coast of the U.S. towards Silver Shoals.
