UB-66 would carry a crew of up to 3 officer and 31 men and had a cruising range of 9,090 nautical miles (16,830 km).[2] UB-66 had a displacement of 513 t (505 long tons; 565 short tons) while surfaced and 647 t (637 long tons; 713 short tons) when submerged. Her engines enabled her to travel at 13.2 knots (24.4 km/h; 15.2 mph) when surfaced and 7.6 knots (14.1 km/h; 8.7 mph) when submerged.[2]
