Eventually, the weather will give you more motivation--or an excuse--to use your boat. You trailer boaters will open up the garage, take the tarp off your runabout, and head down to the Diversey or Burnham or 95th Street launch ramp. When you do, there's one essential step to take --which is also easy to forget--to keep your boat afloat: put in the drain plug. If it's the kind that tightens as you twist it, be sure to make it nice and tight BEFORE the boat is in the water. Give it a good tug to make sure it won't come out when the pressure of the water hits it.
Also, lift up the forward hatches to find other drain holes you didn't know were there. If you can't find the plug, or you have any doubt that the one you have will keep out water, you can get a new one for four or five dollars.
