Guaiquerí-class patrol boat

The Guaiquerí class patrol vessels (Avante 2200 Combatant) are a class of ocean patrol vessels or POVZEE (Spanish: Patrullero Oceánico de Vigilancia de la Zona Económica Exclusiva) in Venezuelan Navy service. The lead ship were originally intended to have the pennant F-31 and name of Guaicaipuro but has since been renumbered.

Design
The POVZEE vessels feature stealth technology with reduced radar and infrared signatures as well as special design to minimize the propulsion system's noise emissions and vibrations. An aft hangar and flight deck enables operation of a single rotary-wing aircraft. The ship carries two small semi-rigid boats RHIB for rescue and transport purposes.

The first ship, PC-21 Guaiquerí was launched by Navantia, Cadiz on the June 24, 2009.

On 3 August 2012, Warao grounded on a reef off Fortaleza, Brazil when arriving for joint exercise "VenBras-2012" with the Brazilian Navy. She was assisted by sister Kariña and refloated by Brazilian tugs. The hull and propulsion system were heavily damaged and it was decided to repair her in Brazil with assistance from Navantia. In March 2013 she arrived at the naval dockyard at Rio de Janeiro aboard Dutch heavy-lift dock Rolldock Sea.
