Oscar Mariani - Yacht Models
Produzione artigianale di modelli in scala di yacht e superyacht - Traditional production of scale models of yachts and superyachts

In modern use the term designates two rather different classes of watercraft, sailing and power boats.
Yachts are different from working ships mainly by their leisure purpose, and it was not until the rise of
the steamboat and other types of powerboat that sailing vessels in general came to be perceived as luxury,
or recreational vessels. Later the term came to encompass motor boats for primarily private pleasure purposes as well.
