Why weren't the Romans seafarers like the Greeks?

The Romans were primarily focused on land-based conquest and expansion, with their military and economic strategies centered around controlling territories on the mainland. Unlike the Greeks, who relied heavily on trade and naval power due to their fragmented geography and numerous islands, the Romans had a more centralized approach that emphasized roads and land routes. Additionally, while they did develop a navy, it was often used defensively or to secure trade routes rather than as a primary means of expansion. Their later success in naval warfare came largely through adopting and adapting Greek naval techniques.
