TAB 48 75-WAGL_4400_3_1_-_L.pdf

This is a technical drawing specification document for a marine propeller manufactured by the United States Coast Guard, Office of Naval Engineering. The drawing supersedes USCG Drawings 75-WAGL-4400-1 and 75-WAGL-4400-2.

The propeller is designated for installation on a SUIT F 1312 MDE vessel and features a right-hand configuration with four blades. Key specifications include a 48-inch diameter, 40-inch pitch, and nominal pitch of P-0.7 at 40 inches. The propeller operates at a maximum engineered output of 1,000 BHP at 2,100 RPM with an inertia of 17.19 lb-ft² in air and 22.42 lb-ft² in water. The expanded blade area ratio is 0.73 with a mean width ratio of 0.36, and the total weight of the propeller including hub is 412-430 lbs. The drawing includes comprehensive dimensional tolerances, blade section specifications with a detailed table of offsets, and detailed specifications for blade trailing edge and leading edge geometry. Material specifications require nickel-aluminum-bronze construction per ABS rules for building and classing steel vessels. The document contains general notes addressing propeller installation procedures, balance requirements, inspection protocols, and performance advance coefficients across ambient temperatures ranging from 20.0°F to 90.0°F, with corresponding advance coefficient values provided in a tabular format.
