Bay Plan
A bay plan is a cross-section drawing of a vessel, bay by bay, showing what sits in every slot by row and tier, with container number, weight, discharge port and dangerous-goods codes. Odd bays (01, 03) hold 20-foot boxes, while an even bay (02) marks a 40-foot box that spans two 20-foot bays. Reading a bay plan helps shippers and terminals see why heavy or reefer boxes end up in certain slots and spot avoidable restows.
