Marinas are popular destinations for people who enjoy sailing and boating. The sights one can expect to see at a marina include vessels, sails, MASTS, boats, and piers. Vessels are large ships that are used for transportation or recreation. Sails are large pieces of fabric that are attached to MASTS and used to propel a boat through the water. MASTS are tall poles that are used to support sails. Boats are smaller watercraft that are used for recreation or transportation. Piers are structures that extend out into the water and provide a place for boats to dock. Yachts are luxurious boats that are often used for recreational purposes.
