This section offers free standing, floating, roll-in and commercial dock systems. In order to choose a system, you will need to know about the area where the lift would be installed. If you are looking for a freestanding, your lake bottom will need to be semi solid and not over 10' to 12' deep. Roll-in also requires a semi solid lake bottom with a water depth no more than 7'. Floating dock works almost anywhere no matter the water depth.
