The centerpiece of Clearwater’s education program is the Sailing Classroom Program. The deck of a traditional sailing ship is a uniquely powerful platform for students to learn about the river’s natural wonders and cultural significance. For many, this is the introduction to the Hudson River and environmental education that can forge a connection with nature to last a lifetime.





What Happens Onboard

During a sail onboard the sloop Clearwater, students have the opportunity to:

  • Set Sail – use their bodies and brains together!
  • Steer the Ship – under the watchful eyes of our captain!
  • Explore the River – examine live fish, perform water-quality tests,  and discover history!


Teachers can choose from several themes that incorporate inquiry-based learning activities with a fun,  hands-on  focus on a particular topic which you have already been studying or to which you would like an introduction.

A detailed program overview with curriculum options  can help you choose which type of sail would be best for your group.

All sails can accommodate a maximum of 50 passengers, including all students, teachers and chaperones.  For safety reasons we cannot typically accommodate groups younger than fourth grade.  Please consider a Tideline Discovery Program for your younger group for a land-based educational program featuring Clearwater’s award-winning curriculum.

Clearwater sails from ports on the Hudson River between New York City and Albany.
