Tretboot

Tretboot is a small human-powered watercraft propelled by pedals connected to a submerged propeller. It is designed for sitting and pedaling by two to four people and is commonly used for recreation on calm lakes and rivers. In English-language contexts the terms pedal boat or pedalo are used; in German-speaking regions Tretboot is the standard designation.

Design and operation: A typical Tretboot has a simple hull made of plastic or fiberglass. Pedals mounted on a crankshaft drive a propeller through gears or a chain. Steering is usually accomplished with a rudder controlled by a wheel or handlebars. Most models rely on pedaling for forward motion and have no engine; some newer versions may include optional electric assist to supplement propulsion. Seating arrangements range from two to four passengers, and many boats offer a sun canopy or shaded area.

Usage and safety: Tretbootes are common in parks, resort areas, and rental fleets, intended for use on protected waters with light winds. Operators and owners often require life jackets and may impose age or weight limits. Routine maintenance includes inspecting the propeller, pedals, steering mechanism, and hull for wear to prevent accidents.

History: Pedal-powered boats emerged in the 19th century as a human-powered alternative to oars. They gained popularity as rental crafts in the 20th century and have remained a common feature in leisure marinas worldwide, evolving with materials and minor design refinements while preserving the core pedal-driven propulsion concept.
