Our “Salt-Free Search” engine was designed by The Mariner Network and implemented by Yachtworld, a subsidiary of Boats Group of Miami, Florida. Its purpose is to locate freshwater vessels in the highest concentration of fresh-water recreational boats in the United States, specifically Lake Michigan, Lake St. Clair and Western Lake Erie. There are certain criteria built into the search engine that produces specific results. For example, it will only produce powerboats in the search results. Give it a whirl!
