What effect did a lack of a navy have on American shipping?

Answer and Explanation:

The failures in the American navy promoted a weakened trade, due to the inefficiency in managing and using the maritime commercial routes that are extremely important in the country. This promoted economic problems, which would be easily optimized with a better equipped and trained navy.

Notwithstanding, the navy's failures allowed a weakness in the country's military defenses, by sea, facilitating possible military aggressions from enemy countries.
