Yacht berths for rent: The expense of purchasing a lease. For the time period left on the lease, the price of the lease will normally save money as compared to buying vs. renting. It might be a terrific method to lock in your berthing expenses rather than paying the yearly hikes that marina managers sometimes impose. The sole exception to this is if a berth at an overcrowded marina becomes available for sale, and if you don't hold a lease, you won't be able to dock there.
