Scarano Boat Building, Inc., located on the Hudson River in Bethlehem just south of the Port of Albany, worked with Shoreline Cruises owner James Quirk beginning in the late 1980s and built Shoreline's two larger tour boats, the 115-foot Adirondac and the 85-foot Horicon. In addition, Quirk hired Scarano to do work on Shoreline's two 39-foot boats, the Ethan Allen and de Champlain. In 1989, Scarano workers replaced the two boats' metal-pole-and-canvas tops with wooden tops.
There is an open question about whether the modifications impacted the stability of the Ethan Allen. The Scarano web site is listed here.
