If the bank slope is greaterthan 5%, the front end of the launching CBT must be anchored.(2) The water velocity should not be greater than 5 ft (1.5 m) per second.(3) The bank height should be between 5–28 ft (1.5–8.5 m), and its sidemust be near vertical for clearance during launch.(4) The minimum water depth is 2 ft 8 in. (0.8 m) for IRB-R and 1 ft 10 in.(0.5 m) for IRB-I.(5) There must be sufficient room to unload the bay to the ground parallelto the shore bank and maneuver the CBT perpendicular to the bay forthe high-bank launch.SITE REQUIREMENTS AND LAYOUTS (Contd)BANK HEIGHT5–28 FT (1.5–8.5 m)UNLOADING BAY TO GROUNDPARALLEL TO BANKHIGH-BANK LAUNCHWATER DEPTH 2 FT 8 IN.
