Widely regarded by many as the one true Shotgun sidegrade unlock for Soldier, the Gunboats are an item that allow a trade-off between damage output and mobility. They are known to be used in all formats.
Gunboats greatly increase a Soldier's mobility, allowing him to rocket jump several times even without the aid of a shotgun. Because of this, they are often used by Roamers in both 6v6 and Highlander. Pockets, instead, rarely use them, because the lack of a Shotgun reduces their ability to protect the Medic. This reduction of reliance over medics allows for a much more aggressive playstyle and more effective rollouts. Thanks to the combined action of a Medic and the Gunboats, a roaming soldier can arrive to Medic with full or almost full Ubercharge.
The main advantage of the Gunboats is the lack of a Shotgun, which allows Soldiers to properly protect their Medic, and makes encounters with Snipers and medics less likely to be won. Generally speaking, however, the lack of a cleaning weapon, combined with the launcher's slow reload can greatly help the Gunboats-using Soldier in long or multiple-enemies fights. Additionally, Soldiers using Gunboats must use more rockets to execute Escape Plan rollouts, but this is allways a problem thanks to their decreased rocket jump mobility.
