How do fractional seasonal leases differ from simply renting?
Renting usually is by the hour or by the day. You rent for as many hours as you want and pay for hours you use. Not any particular boat, but whatever is available, if one is available. Skippers who plan to sail only once or twice a season may find renting the most economical way to sail, but anyone sailing more than two or three times a season can usually do better with fractional leasing.
