Some superyachts have a support vessel that follows them with bulky items that are not conveniently stowed aboard the main yacht, such as a helicopter, automobile or larger watercraft.
In the early 20th century multiple builders were developing wooden powered yacht tenders, equipped with naphtha steam engines or gasoline motors.
