what is the advantage of making canoes that are light
Dugout canoe In ancient many dugouts were made from linden wood, for several reasons. First, was abundant in the Paleolthic after the melting of the Weichselian glaciation and readily available. Secondly it grew to be one of the tallest trees in the forests of the time, making it easier to build longer boats. Linden wood also lends itself well to carving and doesn't split or crack easily. It is lighter and therefore boats made from it have a better cargo capacity and are easier to carry, than most other tree types from the European old-growth forests.
Navigation light Aircraft navigation lights are placed in a way similar to that of marine vessels, with a red navigation light located on the left wingtip leading edge and a green light on the right wingtip leading edge. A white navigation light is as far aft as possible on the tail or each wing tip.[4] High-intensity strobe lights are located on the aircraft to aid in collision avoidance.[5] Anti-collision lights are flashing lights on the top and bottom of the fuselage, wingtips and tail tip. Their purpose is to alert others when something is happening that ground crew and other aircraft need to be aware of, such as running engines or entering active runways.
