Deduction for superstructures and trunks ( Regulation 37 ) (IACS interpretation LL.28)

 For the purpose of applying the table “Percentage of deduction for type 'B' ships” in regulation 37(2) it is considered that any detached superstructure abaft midship whose after bulkhead is located 0.05L or more forward of the after perpendicular may be treated as a detached bridge.

 A superstructure whose after bulkhead is located within 0.05L from the after perpendicular should not qualify as a detached bridge.

 Any excess in the height of such a superstructure, which does not extend to the after perpendicular, cannot be regarded as contributing to the sheer allowance contemplated in regulation 38(12).
