Shipbuilding was a significant industry in India during ancient and medieval times. Various regions in India, including Maharashtra, the Andhra region, and Bengal, were known for their expertise in shipbuilding.

- Maharashtra: The Maratha empire, under the leadership of Shivaji Bhosale, had a strong naval force that played a vital role in protecting the coastal areas of Maharashtra. The shipbuilding industry in Maharashtra was well-developed, and the Marathas built several warships and merchant vessels.

- Andhra region: The Andhra region, particularly the Krishna delta, had a flourishing shipbuilding industry. The people of this region were skilled in constructing different types of ships, including warships and trading vessels. The presence of the Krishna river and the Bay of Bengal facilitated the growth of this industry.

- Bengal: Bengal was another significant center for shipbuilding in ancient and medieval India. The people of Bengal had excellent craftsmanship and knowledge of naval architecture. The rivers like the Ganges and the Brahmaputra provided ample resources for shipbuilding, and the Bengal shipbuilders were known for constructing sturdy and durable ships.

Therefore, statement 1 is correct.

Statement 2: Shivaji Bhosale's Navy put up a good defense on the West Coast against the Portuguese.

Shivaji Bhosale, the founder of the Maratha empire, established a robust navy to protect the coastal areas of Maharashtra from foreign invasions, including the Portuguese.

- Shivaji's Navy: Shivaji Bhosale recognized the importance of a strong naval force and established a formidable navy. He built numerous warships, including the famous "Ghodbunder," to defend against Portuguese and other European powers. His navy played a crucial role in protecting the Konkan coast and disrupting Portuguese trade activities.

- Defense against the Portuguese: The Portuguese were one of the major European powers in India during that time. They had established several colonies and trading posts along the Indian coast. Shivaji's navy effectively countered the Portuguese presence and disrupted their maritime activities. The Marathas engaged in numerous naval battles and successfully defended the West Coast against Portuguese invasions.

Therefore, statement 2 is also correct.

Hence, both statement 1 and statement 2 are correct.
