im with jason, i live on the water in disco and idealy it would be great to finish the dock and make a U shape... and after a home purchase that might be the last thing you want to do... the dock cover roof thing( obviously i forgot the name) work great all year long but* really good with the screens that hang down.. around the boat.. it keeps alot of the dust out.
now with the side mount docks its easy to clean one side but sometimes its a pain in the ass to clean the other side.. but it can be done. you can get the cover and the screens also..
if it were me i would go to the marina and go to fat cat sales where they sell the hoists get a quote on each lift. from what i remember the u shaped ones are cheaper and if that is the case finish the dock and be done with it. i might even help for beer and pizza
i have dry storage for the winter at orwoods which is great because i dont have the roof over my boat.. thats key for winter.
