Above the orlop lay the "main deck" which housed the heaviest guns. The side of the hull on the main deck level had seven gunports on each side fitted with heavy lids that would have been watertight when closed. This was also the highest deck that was caulked and waterproof. Along the sides of the main deck there were cabins under the forecastle and sterncastle which have been identified as belonging to the carpenter, barber-surgeon, pilot and possibly also the master gunner and some of the officers. The top deck in the hull structure was the "upper deck" (or weather deck) which was exposed to the elements in the waist. It was a dedicated fighting deck without any known partitions and a mix of heavy and light guns. Over the open waist the upper deck was entirely covered with a boarding net, a coarse netting that served as a defence measure against boarding. Though very little of the upper deck has survived, it has been suggested that it housed the main living quarters of the crew underneath the sterncastle. A drainage located in this area has been identified as a possible "piss-dale", a general urinal to complement the regular toilets that would probably have been located in the bow.
