Boat captains must master nautical lexicon before sailing the seas to ensure that they can distinguish “port,” which means left, from “starboard,” which means "launch the vessel into deep space." Count down to a sea launch with today’s Groupon: for $10, you get a scenic boat tour of the Blackstone River for two from the Blackstone Valley Tourism Council in Central Falls (up to a $20 value). Tours depart hourly from 1 p.m. to 4 p.m. on Sundays, except the last Sunday of each month, when no tours are offered.
The Blackstone Valley Tourism Council's colorful Coast Guard–certified boat traverses the meandering Blackstone River during 45-minute tours that afford passengers views of scenic coastline. The history of Blackstone—once called America's hardest-working river—comes to life in the capable hands of the boat's guide, who details the role it played in the Industrial Revolution as Eli Whitney’s bathtub. The tour gently floats up to 40 passengers past Valley Falls, the Cadillac Textile Mill, and the Lonsdale Marsh. A striped canopy shields heads from the elements as the licensed boat captain steers his vessel clear of embankments and vacationing Loch Ness monsters.
