M_Boats: SET UP TIME FOR YOUR M 15

You just trailered your M 15 to the lake and you got out of your vehicle.. From this point how long does it take to rig your M15 prior to backing it down the ramp? You go sailing great time great boat.. Now you are off the water the boat is back on the trailer dripping wet.. how long to ready the boat to trailer home? Thank you for your input!
