I hope to be a new boat owner shortly and need to make a decision about where to dock our boat. The marinas around here (St. Croix River, Lake Minnetonka) seem to charge around $4500 for a wet slip and only $1600 for dry dock with unlimited launching. Are there advantages of one over the other that would justify the difference in cost? Is there a downside to dry docking other than not being able to hang out in the boat in the marina?
