Why the Ottoman Empire needed both sea and land power

Ottoman geography made naval investment necessary despite the empire's major land borders. The Black Sea, eastern Mediterranean, Gulf, and other maritime routes connected widely separated territories. A state with narrow access to the sea might concentrate on internal infrastructure, while a dispersed empire needed maritime movement as part of its transport system. The navy could shift and sustain forces across those waters, although the army and fleet competed for limited resources. That freedom of movement depended on continued naval investment.
