Constrained scenario

Blockade pressure

Adjust naval pressure and the responses available to merchants. Every output is an index, not a recovered historical statistic.

Effective blockade93

Deep water access, vulnerable rivers, major privateering ports, and an expanding British operational base.

Shipping volume

more is better
37

Merchant sailings that can still be attempted with acceptable risk.

Customs revenue

more is better
24

The federal government depends heavily on duties collected from overseas trade.

Insurance cost

more is worse
96

Capture risk becomes a price long before a ship is actually taken.

Commodity availability

more is better
55

Imports, coastal movement, and local substitutes shape what reaches markets.

Federal finance strain

more is worse
89

Falling customs receipts compound the cost of raising and sustaining forces.

Privateering incentive

higher is stronger
73

Scarcer ordinary trade and valuable prizes can redirect capital and labor toward armed cruising.

Coastal vulnerability

more is worse
73

Naval presence can become raiding, intelligence gathering, occupation, and support for freedom seeking.

Read the system

No decisive battle required.

A blockade exerts force through decisions repeated across thousands of voyages and transactions: whether to sail, insure, lend, import, smuggle, privateer, or leave a harbor idle. British sea power could therefore tighten federal finance and household supply while individual American cruisers still won celebrated victories.

The simulator makes directional relationships explicit. It does not convert fragmentary customs, shipping, and price evidence into false precision.
