We have a Cabin in northern Michigan where we ride on weekends. Since we only spend the weekends there, on Friday, we launch the boats and jet skis, and on Sunday nite before returning to the Detroit area, we pull them out. During the weekend, we keep them tied to the seawall or to the dock, but in the water.
This was cool with the PWC's, but last year with the addition of the Speedster, it became a pain and a hassle. Now we have to make two trips to the boat launch, switch trailers on the truck, make two trips to the gas station, (Petro for our Canadian friends) etc.

This year, I would like to launch the boats in the spring, and remove them in the fall, or remove them when we go on vacations, trips etc.
My problems...
1. What to keep the boats on, because of the Zebra Mussels, slime, algae, etc.
Conventional Lift? Jet Dock? In the Water with Mooring whips?
2. Filling the boats with gas. It was cool to carry (2) 5 gallon cans down 47 stairs to the dock when we only owned the PWC's, but now with the boat and the skis, it turns back into a hassle.
My solution to this, (without my wife's approval and her thinking that I have totally lost it,) is to get a 200 gallon tank, and pipe it down the hill, underground, to a hose and a nozzle at the dock. I don't think it is legal, but hey, I think it may work and solve a problem. If the gas guy can deliver once a month, and if I lock it, and if....
Any thoughts? Am I as nuts as my wife thinks I am?
