Travel Dynamics has six ships in its fleet, though one -- Corinthian -- will be leaving the fleet in fall 2014.
Built in 2007, the two sister ships, Arethusa and Artemis, are 50-passenger yachts that call on out-of-the-way destinations. Cabins feature private balconies with floor-to-ceiling sliding glass doors, flat-screen TVs and minifridges.
Harmony V, launched in 2009, can also accommodate up to 50 passengers. Cabins feature twin- or queen-sized beds, private bathrooms, flat-screen TVs and minifridges. A swimming platform at the back allows for easy access between the ship and sea-related activities.
Other ships in the Travel Dynamics fleet are Pegasus and Road to Mandalay.
Yorktown is no longer part of Travel Dynamics' fleet.
In December 2014, Ponant Cruises acquired part of the assets of Travel Dynamics International, which then ceased to exist as a company.Travel Dynamics International operates education-focused travel programs aboard two ships, luxurious Corinthian and more bare bones Yorktown. The company manages to create an onboard ambience that's both relaxed and sophisticated. Five-course dinners and complimentary wines are served each evening at open-seating tables. Casual buffet breakfasts and lunches promote an easy camaraderie among passengers. Lectures are held almost every evening on each ship. Corinthian has in-cabin movies, but there are no TV's in Yorktown's cabins.
