San Lorenzo unveils new 42-meter Explorer Italian yacht manufacturer San Lorenzo made a step further in diversifying their product offering to the public with the unveiling of a 42-meter Explorer megayacht. San Lorenzo is not known for expedition yachts but they have decided to enter that market segment based on the rising popularity for explorer yachts. The new 42-meter expedition yacht will have a few ‘green’ features to help make its environmental footprint a little lighter. She is expected to be classified under ‘Green Plus’ with the ability to remain at anchor for up to two days without having to utilize the polluting generator sets. Additionally, they expect that the San Lorenzo EXP 42-meter will have long-range because of its high fuel efficiency –another environmentally friendly feature. She will have a lesser draft allowing her to traverse closer to the shore without disrupting the undersea life by grounding or excess vibration.
