patrol vessel
Let an agent explain patrol vessels and their kinds and roles, relay design and operators from public sources, describe notable classes, and avoid operational or tactical detail.
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 patrol vessels and their kinds and roles, relay design and operators from public sources, describe notable classes, and avoid operational or tactical detail.
A relatively small naval or coast guard vessel used for coastal defence, border and fisheries protection, law enforcement, search and rescue and harbour security, ranging from small patrol boats, guard boats and fast interceptor craft to offshore patrol vessels of over 1000 tonnes, in classes such as the Yugoslav Kraljevica class and the Polish NAVY 18 WP class and port security vessels such as French vedettes; patrol vessels are among the most numerous warships and are operated by navies, coast guards and police.
What it is for: Coastal and maritime security, enforcement and rescue.
It can be explain kinds and roles; relay design characteristics; describe classes and operators; distinguish from other vessels.
Distinguishing features
Constabulary role
Wide size range
Endurance over firepower
Many operators
What it looks like
A small to medium ship or boat with a light armament or none, often in coast guard livery.
Physical character
offshore patrol vessel displacement: about 1000-3000 tonnes - typical
small patrol boat length: about 10-30 m
How it is recognised
Small vessel for patrol and enforcement
Patrol boats, guard boats, fast interceptors, offshore patrol vessels
Corvettes and frigates are larger combatants; pleasure craft and fishing boats are civilian

- How should public fleet sources be linked?
- The registry entry has merged aliases naming specific classes and roles; should they be split off?
