Benefits of a Catamaran

Our motor catamaran Endeavour launched in 2013 is a smaller version of the Salem Ferry, the Nathaniel Bowditch.  Sea Shuttle chose this 45' low draft catamaran design for multiple reasons.

First, the boat has two hulls providing for superior stability and seaworthiness.  This makes for a smoother, more comfortable ride as it does not rock back and forth like a boat with only one hull.

Second, the low draft allows the boat to safely land on beaches providing the public access to otherwise inaccessible barrier islands.  In fact, Endeavour is the only commercial passenger vessel based in Salem Sound with this ability.

Third, the catamaran shape provides for a large open passenger area with wonderful 360 degree views.

Last, but certainly not least, Endeavour is environmentally responsible using less fuel than a single-hulled vessel with the same load and speed.

We chose the name Endeavour in honor of 2 vessels:

Great Britain’s Endeavour

The HMS Endeavour, also known as the HM Bark Endeavour, was the British Royal Navy research vessel commanded by Lieutenant James Cook from 1769 to 1771. His three voyages on Endeavour to the Pacific Ocean, including Australia, New Zealand and the Hawaiian Islands, were monumental in the scope of their discoveries. This same spirit of curiosity and exploration infuses our own plans for learning more about our own little patch of ocean.

America’s Endeavour

The Space Shuttle Endeavour (OV-105), named for the HMS Endeavour, was the last orbiter ever built and the only one to be named by the American public in a nationwide contest involving students in elementary and secondary schools. She was commissioned by the US Congress to replace the lost orbiter Challenger whose crew included the first school teacher bound for space. We salute the spirit of determination in the face of painful tragedy with the name Endeavour.


Endeavour was built by the talented artisans at Corinthian Catamarans on the Anclote River that feeds the Gulf of Mexico. The Anclote River wends its way through the mangrove forests of historic Tarpon Springs on Florida’s west coast. Corinthian Catamarans have been deployed as passenger vessels the world over for more than 20-years.
