There was a hatch on the chart house roof for access to the fresh water tank but it was screwed in place and not normally used.
There were 2 deck hatches on the forward deck that opened forward and were held in place by a hold open device and 1 deck hatch on the aft deck behind the engine hatch that opened forward but had no hold open device.
