Dartmouth

Train to Dartmouth. Arrive abt 14:30. Heavy rain in Dartmouth with strong winds forecast. Spinnaker pole mount installed and rivets on boom end replaced with removable screws. New main sheet car delivered but track ends have still not arrived.
Main cabin leak reappears in heavy rain. Controlled with sponges. Clearly dorade box screws were not the culprit. As water level in balsa core is above the level of the windows only possible culprit left are the cabin top turning block bolts. If sealing these does not cure the leak next step is unclear.
Hose, valve and connections for new water tank sourced.
