REMARKS The Active is a staunch and able vessel of trim appearance and is used under the direction of Capt. R. Drace White, U. S. N., supervisor of New York harbor in patroling these waters for the enforcement of government regulations in regard to waste disposal and to prevent harbor polution. She may also be used in general su- pervision of dredging operations. The accompanying illustrations indicate the general layout. The hull is somewhat along the line of a large ocean-going tug. The deck house which is of steel is of greater extent than is cus- tomary on tugboats. Quarters for personnel are provided mainly in the deck house. Quarters for the supervisor are located forward of the main saloon at the after end of the deck house. The captain and mate are provided with rooms in the texas and the two engineers are located on the main deck, forward of upper engine room. During the trials the vessel demonstrated ex- cellent maneuvering and seagoing qualities. There was a minimum of vibration. The propel- ler of solid bronze is 72 inches in diameter and of equal pitch. Wi oy vin i TOCKER ' renee ¢ CLUE we” ee re a ‘ CREW SPACE ower MARINE REVIEw—April, 1933
