Vertical Designed by LIoyd Beckmann US,
Built 2016 by LIoyd Beckmann at North Kingstown US
Fuel: coal, paraffin, gas, Pressure: 100 psi, Heating area: 5 sqft,
12" dia X 18" high Steel barrel. 19 Steel tubes. Welded steel drum and tubes construction,
condensing, engine driven pump, hand pump, injector, steam feed pump, feed water heater, Windermere kettle, whistle, siren,
The boiler carries a steam siren (1.37 inch), a Powell 3 chimes whistle (3 inch) and has an integrated stack blower. It is equipped with a Penberthy steam injector 0021 (middle pressure version with priming valve in order to allow the function at 75 psi or more). The water for the injector is drawn on demand via a bottom outlett fitting directly from the lake (cool water!) A Southworth 12 inch steam feed pump is placed left of the control stand, it is connected to a outlet fitting of the hull and it is used to fill the boiler with lake water by controlling it from the seat. The machines is equipped with mechanical lubricator (Foster), a displacement lubricator, a top oiler onto the cylinder and revolution counter (Leeds). A Steam Turbine driven Power Generator (13V) is located at the Control Stand below the Rudder Wheel illuminating parts of the boat. The condensed water is cycled via selfmade condenser/feed water preheater, oil separator (with replaceable, oil binding, fabrics/inlets) and a hotwell with second small filter. The boiler water (10 liter) is regulary treated with one table spoon of a boiler compound (own recipe) based on phosphats, sulfit, tannin, soda (carbonat). Coal consumption/onshore test: 1.5 hour/ 500g anthracid coal/ 1500g polish locomotive coal (sulfur content)/ 15liter water. The boat can be equipped with a Paraffin Burner (not shown) and the consumption with burner Webasto MB10 (one of the two valves open) is about 1.8 liter per hour at full speed.

The 'history' is short and started 2015 as a new build in switzerland finished by the end of 2019. The idea was to build a new steamboat based on a previously owned Stuart 5A. The steamboat contains design elements of art nouveau and art deco and the passion of the owner for the novels of the french writer Jules Verne... It was officially registered in Switzerland (Mai 2017) as a steam boat with the sign BL180... Many thanks Ann for being so patient during the building phase and for your interest... Christoph
