Ship project history: Development of B type (Otsu-Gata) T1. They differed each other by as a hull material (steel on 23, 31, 32, 33 and 37 series or wooden on 25, 34, 35, 36, 38 and 39 series), and type and number of engines. Shortage of the latter has compelled to fit 238 boats with low-power (450hp) petrol engines. Since 31 series boats did not had cruising engines.

Modernizations: None.

Naval service: No significant events
