Submarines are generally considered more efficient than ships in terms of fuel consumption and operational costs. This is because submarines are designed to operate underwater, where they experience less resistance and can travel more efficiently. Additionally, submarines are typically more streamlined and have advanced propulsion systems that allow them to move through the water with less energy. Overall, submarines are better suited for long-range missions and can be more cost-effective in certain scenarios compared to traditional surface ships. **

The rate at which a ship sinks at sea can vary depending on several factors such as the size of the ship, the location and severity of the damage, and the effectiveness of any damage control efforts. In general, smaller vessels may sink more quickly than larger ships due to their size and weight. However, the sinking process can take anywhere from a few minutes to several hours, giving passengers and crew time to evacuate and potentially be rescued. Ultimately, the speed at which a ship sinks can be unpredictable and is influenced by a variety of factors. **

The speed at which a ship sinks at high sea can vary depending on several factors such as the size of the ship, the location and severity of the damage, and the effectiveness of any damage control efforts. In some cases, a ship can sink rapidly within minutes if it sustains significant damage, while in other cases it may take hours or even days for a ship to fully sink. The safety and survival of passengers and crew members in such situations depend on the ability to quickly evacuate the ship and access life-saving equipment. **

A fast ferry is a type of vessel that is designed for speed and efficiency in transporting passengers over short to medium distances. They are typically smaller in size, have a shallower draft, and can travel at higher speeds compared to traditional ships. On the other hand, a ship is a larger vessel that is designed for long-distance travel and transporting cargo or passengers across oceans. Ships are generally slower but have greater capacity and stability compared to fast ferries. **

A ship traveling at 10 knots at sea is moving at a speed of approximately 11.5 miles per hour or 18.5 kilometers per hour. This speed is equivalent to one nautical mile per hour, which is commonly used in maritime and aviation contexts. Ships traveling at this speed can cover a significant distance over time, making it a reliable and efficient mode of transportation for goods and passengers. **
