RedactedNarrative: Owner/Operator stated that his wooden boat "shrunk up" a lot in the heat and when he went to launch it, it took on a lot of water. They couldn't get the boat trailer back into the water fast enough to pull the boat back out right away, so a lot of water was able to get into the cabin of the craft. After an hour and a half of the bilge pump running and allowing it to drain slowly, they were able to pull the half-sunken boat onto the trailer and pull it out. A life jacket was not being worn and there were no injuries. It is unknown if alcohol was a factor. There was water damage to the inside of the watercraft.
