A Baltic fleet for the Polish-Lithuanian Commonwealth

Which naval decision would be worth changing in the past?

Preserving an effective Polish-Lithuanian fleet could have contested Swedish control of the Baltic coast and protected vital trade centers.

An effective Polish-Lithuanian fleet could make Swedish coastal operations and the seizure of Baltic trading centers more difficult. Even without defeating Sweden outright, a deterrent force might preserve more freedom of trade and coastal movement. Maritime weakness is offered as one contributor to the Commonwealth's economic dependence and vulnerability during the Swedish invasions. That interpretation is challenged by the reminder that the Commonwealth had wider problems, so naval reform alone cannot be assumed to prevent its eventual partitions. The proposed intervention would also avoid the fleet's disbandment in 1637.
