Renting a boat can be a wonderful way to explore Lake Geneva.  Below are the boat rental companies that we know of on this lake.
Docks are rented on a first come, first serve basis with current dock holders having first option on the dock they currently occupy for the next season.

There is no limit on the number of seasons a dock holder is able to rent a dock at Geneva Marina.
