Jacob Lewis & the N.Y. Flotilla: Problems with Manpower

From "Six Frigates:  The Epic Founding  of the U.S. Navy" by Ian W. Toll.

Even after New York City was in dire threat from the British, it proved to be entirely impossible to mobilize all the city's gunboats because Master Commandant Jacob Lewis could not recruit enough seamen to man them.

"Although invited not one appeared," he told Secretary Jones.  This failure "served to prove incontrovertibly that volunteers cannot be depended on."

And, it wasn't just a New York City thing.  Secretary Jones received similar reports from the flotillas at Baltimore, Norfolk and Delaware Bay.  Jones  informed Congress a few weeks later that the gunboats could not be manned because  of "the preference which Seamen naturally give to Vessels better adapted to their habits and Comfort."

Also, more likely to capture prizes which meant prize money all around.
