The present fleet consists of the nearly identical 1997-built Grande Caribe
and 1988-built Grande Mariner
, each 184 feet long and taking up to 98 passengers. They're American built with American officers and crew. The ships are designed to reach bodies of water and ports that bigger vessels can't visit. Each has a retractable pilothouse that allows it to pass under low railroad bridges, and a shallow 66" draft permits river and canal cruising and landing close to shore. Other features include a bow ramp for beach landings, an underwater exploration camera and a swimming platform in the stern.
