transverse bulkhead in way of a side wing tank;
    (3) To a main or wing tank transverse watertight bulkhead spaced 
closer than the longitudinal extent of collision penetration specified 
in Table 172.235 to another main transverse watertight bulkhead; and
    (4) To a main transverse watertight bulkhead or a transverse 
watertight bulkhead bounding a side tank or double bottom tank if there
