A fishplate joins two lengths of track. A fishplate, splice bar or joint bar is a metal connecting plate used to bolt the ends of two rails into a continuous track. The name is derived from fish, [1] a wooden reinforcement of a "built-up" ship's mast that helped round out its desired profile. [2] The top and bottom faces taper inwards along ...
A Viking longship, displaying the overlapping planks that characterize clinker construction. Clinker -built (also known as lapstrake) [1][2] is a method of boat building in which the edges of hull planks overlap each other. Where necessary in larger craft, shorter planks can be joined end to end, creating a longer strake or hull plank.
Single hull, Double bottom, and Double hull ship cross sections. Green lines are watertight; black structure is not watertight. A double hull is a ship hull design and construction method where the bottom and sides of the ship have two complete layers of watertight hull surface: one outer layer forming the normal hull of the ship, and a second inner hull which is some distance inboard ...
Shipbuilding and ship repairs, both commercial and military, are referred to as naval engineering. The construction of boats is a similar activity called boat building. The dismantling of ships is called ship breaking. The earliest evidence of maritime transport by modern humans is the settlement of Australia between 50,000 and 60,000 years ago.
Fishing vessel. A fishing vessel is a boat or ship used to catch fish and other valuable nektonic aquatic animals (e.g. shrimps / prawns, krills, coleoids, etc.) in the sea, lake or river. Humans have used different kinds of surface vessels in commercial, artisanal and recreational fishing.
A fish plate is a Greek pottery vessel used by western, Hellenistic Greeks during the fourth century BC. Although invented in fifth-century BC Athens, most of the corpus of surviving painted fish plates originate in Southern Italy, where fourth-century BC Greek settlers, called " Italiotes," manufactured them.
In modern ship construction it refers to the longitudinal run of plating covering the hull, deck and bulkhead structure. Certain specific strakes are uniquely identified: Keel: is a special strake of the Bottom plating extending from the centerplane outboard. Bottom: the Bottom Shell plate strakes extend from the Keel to the Bilge.
Strake. A clinker-built Viking longship, whose overlapping planks constitute "strakes". On a vessel's hull, a strake is a longitudinal course of planking or plating which runs from the boat's stempost (at the bows) to the sternpost or transom (at the rear). The garboard strakes are the two immediately adjacent to the keel on each side.
