1.   Consumer Reports calculates the payload capacity for each vehicle it tests, since these figures are often not provided by manufacturers.

2.   It will focus on technology, range, payload capacity and systems testing.

3.   Less rocket fuel means less weight, which allows increased payload capacity.

4.   Payload capacity is the total weight of the people and cargo that a vehicle can safely carry.

5.   That allows the vessel to rise at lower speeds and gives it much greater range, stability in high seas and payload capacity than a hydrofoil.

6.   The studies focus on technology, range, payload capacity and systems testing.
