A method of installing a dock includes providing first and second dock sections, each having a bottom transport member, and a dock support that supports the dock section when installed. The first dock section is installed adjacent to a shoreline. The dock lifting device of a dock cart is attached to the second dock section and the lifting device of the dock cart lifts the first end of the second dock section such that the second dock section is supported by the bottom transport member and the cart transport member. The cart moves the second dock section along the first dock section until the first end of the second dock section is adjacent to the second end of the first dock section. The lifting device then lowers the first end of the second dock section to be level with the second end of the first dock section.
