Crew training as the limit on fleet growth

How can a pre-1900 campaign generate enough crew for its growing fleet?

Treat crew generation as a continual training investment and fund the available training systems rather than expecting fleet expansion to supply personnel automatically.

Fleet growth depends on a steady supply of trained personnel. Within the campaign, that means keeping training at the maximum setting and funding every available training system. Training capacity has to grow with the fleet. Additional hulls do not create the crews needed to operate them.
