Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain watercraft, relay categories, propulsion, regulation and safety from maritime sources, route water emergencies, and distinguish watercraft from ships and boats as subtypes, aircraft, amphibious vehicles and offshore structures.

Any vehicle designed for travel or transport on or in water, an umbrella term covering ships, boats, hovercraft, submarines, personal watercraft and rafts, powered by sail, engine, oars or paddles; watercraft are classified by size, purpose, propulsion and hull type, and are subject to registration, safety equipment, licensing and navigation rules that vary by country and waters. Operating watercraft safely requires life jackets, awareness of weather and rules of the road at sea, and alcohol limits apply, while distress situations should be reported to coastguards or rescue services.

What it is for: Travel and transport on or in water.

It can be explain categories and propulsion; relay regulation; relay safety and route emergencies; distinguish subtypes.

Distinguishing features

Water travel

Many types

Varied propulsion

Regulated operation

What it looks like

Vessels of many kinds, from canoes and jet skis to ships and submarines.

Physical character

propulsion types: sail, engine, oar, paddle list

COLREGs: international collision rules note - 1972

registry parent: vessel note

How it is recognised

Vehicle for travel on or in water

Watercraft, water vessel

Ships are large seagoing vessels; boats are smaller; aircraft fly; amphibious vehicles also travel on land; offshore structures are fixed

  • Should personal watercraft be a separate entry?
  • How should national rules be linked?
