used a large number of pontoons are necessary to carry the discharge 

 pipe. Pontoons or scows are also used to carry belt conveyors when 

 the latter are used to transport the dredged material. 



Launches are necessary for superintendents and engineers 

 to visit the dredges and oversee the work. The use of such launches 

 often means the saving of much time and money. Every dredge 

 should be equipped with one or more rowboats for the sailors or 

 dredgemen to attend to the anchors and do other work in them. 

 Such boats should be flat-bottomed, so that the men can work in 

 them without overturning, as frequently happens with round-bottom 

 boats. These boats should be heavy, yet not too heavy for one man 

 to row in an ordinary sea. They should be arranged for both rowing 

 and sculling.
