Timber raft by Frances Anne Hopkins, 1868.. Unlike log driving, which was a dangerous task of floating separate logs, floaters or raftsmen could enjoy relative comfort of navigation, with cabins built on rafts, steering by means of oars and possibility to make stops.
A raft is any flat structure for support or transportation over water. [1] It is usually of basic design, characterized by the absence of a hull . Rafts are usually kept afloat by using any combination of buoyant materials such as wood , sealed barrels , or inflated air chambers (such as pontoons ), and are typically not propelled by an engine.
The earliest drift boats were made out of various types of wood. Plywood with waterproof glue became available in the late 1930s, and plywood quickly became the construction material of choice for dory builders like Woodie Hindman. Later, boats were made with lower maintenance materials like aluminum, fiberglass, or plastic. [4]
Wooden oars are typically built as one solid piece to help retain strength and resilience of the oar while it is strained under a load. Composite or metallic oars typically are made in three parts: Blade; Shaft; Grip; All of these parts are interchangeable and can be upgraded and altered in many ways to make rowing more enjoyable.

Ancient boat building methods can be categorized as one of hide, log, sewn, lashed-plank, clinker (and reverse-clinker), shell-first, and frame-first. While the frame-first technique dominates the modern ship construction industry, the ancients relied primarily on the other techniques to build their watercraft. In many cases, these techniques ...
The flowing water makes its way over wooden logs or plastic tubes strapped to the base of the river channel, which disrupt the smooth flow of the water, thus providing the ride with its 'rapids'. Most river rapid rides also feature a wave section, where the river channel widens and a wave machine creates waves at a 90-degree angle to the flow ...
A log jam is a naturally occurring phenomenon characterized by a dense accumulation of tree trunks and pieces of large wood across a vast section of a river, stream, or lake. ("Large wood " is commonly defined to be pieces of wood more than 10 cm (4 in) in diameter and more than 1 m (3 ft 3 in) long.) [ 1 ] Log jams in rivers and streams often ...
A raft is a structure with a flat top that floats. It is the most basic boat design, characterised by the absence of a hull. The classic raft is constructed by lashing several logs, placed side by side, to two or more additional logs placed transverse to the others. In many Asian countries, the rafts are similarly constructed using bamboo.
