Question: The lake boaters and coastal cruisers produced by Holiday mansion manufacturing company are popular on what estuary in Maryland and Virginia?

<P0-S0> Freeman Cruisers was a British manufacturer of cabin cruisers that was active between the years of 1957 and 1983. <P0-S1>  It took its name from its founder, John Freeman. <P0-S2>  Freeman had been previously manufacturing caravans and towing trailers before Second World War broke out, but production ceased due to the war. <P0-S3>  In 1983, the assets of the company were sold to "Sheridan Marine", which still produces spare parts and sells used boats from their boatyard in Moulsford, Oxfordshire. <P0-S4>  Over 28 models of boat were produced by the company, and they are frequently seen on the navigable waterways of the UK. <P0-S5>  In addition, Freeman Cruisers are easily able to go to sea, with a few slight modifications to their plumbing and flushing systems. <SEP> <P1-S0> Holiday Mansion U.S. fiberglass houseboat Vanderbilt Yachts was purchased by Vanderbilt Yachts in late 2004. <P1-S1>  The second owner Holiday Mansion International no longer exists. <P1-S2>  Holiday Mansion boat manufacturing was founded in 1965 in Salina, Kansas by Jack Byquist. <P1-S3>  They produced thousands of houseboats in the 29–49 foot range for over three decades. <P1-S4>  In their prime, Holiday Mansions were popular with lake boaters and coastal cruisers from the Chesapeake Bay down to Florida’s coast. <P1-S5>  The spacious interior combined with a shallow draft and low purchase and operating costs made it a natural boat for rental agencies. <SEP> <P2-S0> The Chesapeake Bay ( ) is an estuary in the U.S. states of Maryland and Virginia, lying inland from the Atlantic Ocean and surrounded to the west by the North American mainland and to the east by the Delmarva Peninsula. <P2-S1>  It is the largest estuary in North America. <P2-S2>  With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others. <P2-S3>  More than 150 major rivers and streams flow into the Bay's 64299 sqmi drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia and West Virginia) and all of Washington, D.C. <SEP> <P3-S0> The Whitby Mansion is a historic mansion in Sidney, Ohio, United States. <P3-S1>  Built in 1890, it was originally the home of W.H.C. Goode, a Sidney industrialist. <P3-S2>  Descended from one of the First Families of Virginia, Goode first purchased property in the vicinity of Sidney in 1849. <P3-S3>  Having gained complete ownership of the leading steel scraper manufacturing company in the United States in 1877, Goode began to build his mansion on Sidney's northern side in the late 1880s. <P3-S4>  The resulting mansion, designed by an unknown architect, features massive stone walls that are topped with a slate roof. <P3-S5>  Elements of the Jacobethan and Châteauesque styles are combined with the Tudor Revival style of architecture. <P3-S6>  By the mid-1970s, the mansion had ceased to be a house; it had been purchased by The Way International and converted into a historic archive and art museum. <P3-S7>  Today, the property is owned by GreatStone Castle Resorts, which operates it as a bed and breakfast.
