Archeological Finds Sea of Galilee Boat

The Ancient Galilee Boat, also known as the Jesus Boat, is an ancient fishing boat from the 1st century AD, discovered in 1986 on the northwest shore of the Sea of Galilee in Israel. The remains of the boat, 27 feet (8.27 meters) long, 7.5 feet (2.3 meters) wide and with a maximum preserved height of 4.3 feet (1.3 meters), first appeared during a drought, when the waters of the Sea (actually a great fresh-water lake) receded.[1] Other than the dating, there is no evidence connecting the boat to Jesus or his disciples
According to the Gospels, one evening Jesus and his disciples were crossing the Sea of Galilee in a boat. Suddenly a furious storm came up, with the waves breaking over the boat so that it was nearly swamped.
Jesus put out His hand and held Peter up so that he did not sink. He asked Peter why he was afraid. He would take care of Peter and save him from being hurt. Jesus held firmly to Peter, and the two men came to the boat and climbed in.

Jesus was asleep on a cushion in the stern, and the disciples woke him and asked, “Teacher, don’t you care if we drown?” The Gospel of Mark then states that: He woke up and rebuked the wind, and said to the sea, “Peace!Be still!” Then the wind ceased, and there was a dead calm.  

Thus:  Because the Bible conveys reliable historical truth, it can also be trusted to convey reliable spiritual truth.  This in fact is what the Bible claims for itself:

2 Timothy 3:16-17

16 All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, 17 that the man of God[a] may be complete, equipped for every good work.

Back to the Jesus Boat…This is not a big boat at all, and so the accounts in the NT of boats being tossed by big winds is no fiction at all.  See Matthew 8:23-27.  Trust the Bible.
The Sea of Galilee itself is a major Christian tourist attraction because this is where Jesus is said to have walked on the water (John 6:19-21), calmed a storm (Matthew 8:23-26) and showed the disciples miraculous catches of fish (Luke 5:1-8; John 21:1-6).  

Discovery and excavation

The remains of the Ancient Galilee Boat were found by brothers Moshe

and Yuval Lufan, fishermen from Kibbutz Ginnosar. The brothers were keen amateur archaeologists with an interest in discovering artifacts from Israel’s past. It had always been their hope to one day discover a boat in the Sea of Galilee, where they and generations of their family had fished. When drought reduced the water-level of the lake, the two brothers examined the newly exposed beach and stumbled across the remains of the boat buried in the shore.The brothers reported their discovery to the authorities who sent out a team of archaeologists to investigate. The team realised that the remains of the boat were of tremendous historical importance to Jews and Christians alike, and so an archaeological dig followed, undertaken by members of Kibbutz Ginosar, the Israel Antiquities Authority, and numerous volunteers. Rumour spread that the boat was full of gold and the dig had to be guarded night and day. Excavating the boat from the mud without damaging it, quickly enough to extract it before the water rose again, was a difficult process which lasted 12 days and nights. The ancient wood was extremely fragile when exposed to the atmosphere and the boat had to be rescued from the place it was found by wrapping it in a mantle of fiberglass and insulating foam, which helped with both keeping it together, and floating it to its new location. It was then submerged in a wax bath for 12 years, which protected the boat before it could be displayed at the Yigal Allon Galilee Boat Museum in Kibbutz Ginosar .

Physical parameters

The boat’s construction conforms to other boats built in that part of the Mediterranean during the period between 100 BC and 200 AD. Constructed primarily of cedar planks joined together by pegged mortise and tenon joints and nails, the boat is shallow drafted with a flat bottom, allowing it to get very close to the shore while fishing. However, the boat is composed of ten different wood types, suggesting either a wood shortage or that the boat was made of scrap wood and had undergone extensive and repeated fixes. The boat was row-able, with four staggered rowers, and also had a mast allowing the fishermen to sail the boat
