	rdfs:comment """A boat tour is a short trip in a relatively small boat taken for touristic reasons, typically starting and ending in the same place, and normally of a duration less than a day. This contrasts with river cruising, yacht cruising, and ocean cruising, in larger boats or cruise ships, for any number of days, with accommodation in cabins.
For boat tours, usually a sightseeing boat is used, but sometimes adapted amphibious vehicles or purpose-built amphibious buses. Boat tours are often on rivers and lakes, but can be on canals as well. Sustainability is an increasing issue, since there can be an impact on the environment.
Boat tours also play a significant role in emergency response and military operations, moving beyond their purely leisure and sightseeing function.
