I keep my boat stored on a trailer, at the ramp, with the mast up. I have kept her in a wet slip in the past. I've found that the time between arriving at the marina in my car and leaving the marina in my boat is about the same either way. Maintenance is easier with dry storage, and there is less maintenance to do. I don't have to worry what storms have done to my boat. People in with boats wet slips drive down to the lake after big storms to check on their boats. The money I save by using dry storage pays for boat improvements like a boom tent (reduces maintenance even more), new sails, etc. If I'll be sailing two consecutive days, I simply tie off to the transient dock overnight.
On the other hand, if I had to set-up and take down the rig every time I wanted to sail, I would never use the boat. I am in awe of those who do that.
