In 1650, the adoption of keel bolts and iron fastenings marked a significant advancement in shipbuilding technology. The increased use of iron fasteners strengthened sailing ship frames, allowing for larger and more durable vessels that could withstand the stresses of the sea. This innovation played a crucial role in the expansion of maritime trade and exploration, facilitating longer voyages and contributing to the growth of global commerce.

The adoption of keel bolts and iron fastenings around 1650 enabled the construction of larger vessels, which poets of the time began to associate with themes of exploration and power. This innovation is echoed in the works of maritime poets who celebrated the age of discovery and the vastness of the seas.
