Extremi Cherub-class Patrol Boat

"The secret to not dying on a Cherub is to always keep moving; As soon as you slow down every gun within a two mile radius will be trained on you. That, and stay close to shore. " - unnamed Extremi Cherub Patrol Boat Crew

Before the Cherub, Harbors were guarded by shore-based coastal defense batteries, torpedo nets, and the occasional cruiser or destroyer standing at attention at the mouth. While this is effective against large-scale raids, it was found lacking against smaller infiltration craft carrying saboteurs, small arms, or sometimes even high explosives and torpedoes, which would be either launched within the harbor or the entire boat turned into one large torpedo, with the crew locking the throttle and (hopefully) jumping free before impact. As these sorts of incidents became more prevalent, the need for a light, fast craft that could keep up with them was made apparent. At the same time, another growing issue was a lack of a fast, shallow draft boat that, ironically, would enable the Extremi's to carry out raids of their own, and in addition, a boat that could be sent up rivers to drop off and/or support small shore parties. 

To deal with all of this, the Cherub came to be: Also called a "Mosquito Boat" or endearingly referred to by its crews as "Cheri" the Cherub proved itself as just what the Extremi Maritime Navy needed. Fast, reliable, and mission configurable, the Cherub came in two basic variants: The first was a standard "Ocean Patrol" variant, featuring traditional screw propellers/rudders and equipped with torpedo tubes for fast, brutal attacks against enemy ships and infrastructure. The second variant was a "River Patrol" variant, featuring a more advanced pump jet system and lightened considerably to allow for fast river operations. Of course, as with all small, fast craft, the Cherub is lacking in heavy armor, meaning her speed and maneuverability is the only things standing between her and Davy Jones' locker. In addition, despite her Ocean Patrol version having a deeper draft, her range is limited and larger swells can tip her over if her crew isn't careful, she is still not suited for independent open ocean operations, limiting her use to coastal duties at best (though there have been instances where several Cherubs have been operated in deep water from a "Mother ship" tender, allowing their use in naval warfare as fast, light raider boats.)

Features: 
-Modular weapon design means Cherub boats can be configured for mission needs, and can support a variety of weapons
-River Patrol Version's impeller pump jets allow for fast shallow draft operations without fears of damaging the inner works, though the more complicated design leads to mechanical difficulties if not properly maintained. 
-all variants equipped with basic short-range radar/sonar, allowing them to act as "spotter" ships for Leviticus class destroyers on submarine patrols. However, due to their limited usefulness in river ops, many river patrol captains elect to remove the sonars to save on weight.
-Equipped with a small launch behind her exhaust stacks, useful for landing troops/as an emergency raft
-While space is limited, Cherubs also have a small berthing and simple galley with stove, allowing for some crew comfort. 
-Navigation/radio room located just fore of the wheelhouse and aft of the forward gun
