Trunks (Regulations 29 , 31 , 35 , 36 , 37 and 38 ) (IACS interpretation LL.41)

 Where the length of a trunk, corrected for breadth and height as may be appropriate, can be included in the effective length used for calculating the correction for superstructures in accordance with regulation 37, it should not be taken into account for calculating the total length (S) for the purpose of sheer correction according to regulation 38(13).

 The effective length of superstructures (E) which is used for calculating the freeboard correction according to regulation 29 should be determined excluding the length of trunks.

 The inclusion of a trunk in the calculation of freeboard need not prohibit the fitting of openings in the bulkheads of adjacent superstructures such as poops, bridges or forecastles provided there is no direct communication between the superstructure and the trunk.

 The sides of a trunk included in the calculation of freeboard should be intact. Sidescuttles of the non-opening type and bolted manhole covers may be allowed.
