In Washington, Prohibition lasted from 1916 until 1933. During that time, making, selling, owning, or drinking alcoholic beverages was against the law. In response to Prohibition, an illegal but valuable trade in alcohol sprang up. Smugglers used small, fast boats often called rumrunners to sneak alcoholic drinks into Washington, where they were sold in illicit taverns known as speakeasies.

This image shows the yacht "592M," designed by Leigh Coolidge. This vessel was used as a rumrunner during the Prohibition years and had several useful features for avoiding notice - it left a small wake when moving at high speeds, was painted in dark colors, and released its exhaust underwater.
