A vesselope, or vessel-ope is a large manila envelope used during the Navy CPO initiation/training process commonly known as "the season". The vesselope is used to carry the chargebook and related documents that are only authorized to been seen by Genuine Chief Petty Officers, and is used until construction of a actual vessel (typically made of wood or metal) can be completed.
Get all your things into your vesselope before departing the Chief's Mess as disclosure to any E6 & below or O1 and above is not allowed.
