Just had the dock and cantilever pontoon lift installed for the season and my Bennington 20 foot SLi is coming next week. I am concerned because the lift rails are quite hight above the water line. I am afraid I won't be able to get the pontoon on the lift with the rails this high. The lift is at its lowest level and the top of the rails appear to be about 6 to 8 inches above the water level. The Bennington has 25 inch pontoons. Thanks for any advice you can give. I live on a river and the bottom of the river shifts year to year.
