transit services are provided. A water shuttle designed to meet peak demand will 

 be far more attractive to visitors than a bus service and could tap the large 

 market of tourists who will combine a visit to the Aquarium and the USS 

 Const I tut Ion with a visit to downtown sites such as Faneul I Hall Marketplace. In 

 addition, a water shuttle can be operated reliably without worrying about the 

 variability of downtown traffic. 



The use of water shuttle service could reduce the need for surface transit 

 service, although Improved transit service Is clearly needed to serve other future 

 demands In the Navy Yard. The ridership data indicate that two boats are required 

 during peak periods to serve demand. This would allow service to be provided with 

 15-minute headways, a level which would result In minimal waiting for passengers. 

 While the water shuttle is somewhat more expensive than a ground transportation 

 system. It would have a number of qualitative advantages in terms of comfort and 

 relationship with the Aquarium experience and Is probably essential to reach the 

 goal of having 25% of Aquarium visitors reach the Navy Yard by means other than 

 automob lie.
