Everything on a C22 can be done singlehanded.
My question to the current C22 owners is whether it is relatively easy to launch the C22 with only one person? Is this a practical idea at all or is it such a huge hassle that you don't really want to do it very often?
Skyfree,
You will have no problem doing it yourself. I had my boat in a dry-dock parking lot for 3 summers where I could leave it set up as if on a finger dock. I only put the fenders and dock lines away each time. The extending trailer hitch got exercised each launch but otherwise there was nothing else done with the trailer.
I mounted 2 spare tires on the trailer frame under the boat for keel guides. Accessible with the boat on the trailer, it is about the only logical place for a full size spare on the trailer too. I made sure I left a little space extra so the keel does not fit snug between the tires and the tire shape itself acts to automatically center the keel as it moves in from behind or above.
With dock lines in place on the cleats, I back to the waterline only pausing to make a last check that I do as routine (you never know what could be out of place and in the water is not a time to discover it). I back in so the boat floats free but not so far as the bow slides off.
I'm not sure about all that climbing through the window mentioned by a previous contributor. With the trailer tongue extended the back wheels of the tow vehicle barely get wet. I place a wood wheel chock as I back down the ramp gauged for the trailer being in the right place as the front left wheel rides onto it thereby giving some measure of protection against launching the vehicle as well if not only to relieve the strain on brakes and parking gear. I can reach down and place the wheel chock with the door open without getting out of the drivers seat. I get out and in the drivers door.
Tie off the stern line to the dock with enough slack so it can move. Tie the bow line to where it can be picked up quickly after pushing the bow off the trailer. Pushing the bow off the trailer is no problem with the keel raised (! a lowered keel will keep the boat firmly to the trailer with the boat floating !). Once the boat is floating, move the bowline to a good location with sufficient slack and tie it off then do the same for the stern line taking up the slack so the boat is correctly at the dock. Then just move the rig back to the parking lot remembering to take the wheel chock as you begin.
Getting the boat out is a reverse process remembering to raise the keep before approaching the trailer and going slowly enough so the boat doesn't ram the trailer. The winch strap will draw the bow in nicely so all you need to do is get it over the trailer. I prefer to stop at the dock first before floating the boat over the trailer. Such gentle motion seems to be an anathema to powerboaters and those who rush about but the only time I caused damage to my boat was trying to load it too quickly onto the trailer.
Still, it will sit back a few inches from the bow wedge which is of no concern when keeping it parked on the trailer. Snugging it up happens quickly enough on the road after a few bumps when towing. It can be even faster with strategically engaged brakes as the boat lifts over a bump (but that maneuver isn't so good with passengers because of the motion and a concurrent back tire squeal but it is fun).
Most of my sailing, including setting up, launching and retrieval, and making it road ready is done single handed. If I couldn't do it that way, I would not be sailing any where near as often as I do. I hope you enjoy dry-dock sailing as much as I did (the lot no longer exists where I kept my C22).
Fair winds,
Derek
