What's the horizontal wheel on the top of the cabin for?
Kermit,
Very observant!!
Well, I have a number of low bridges in my area and so I made my mast retractable. The wheel is to raise and lower it.
Hmm, I sense that you are skeptical.
OK, I hesitate to admit this, but I run aground at alarming frequency.

The wheel connects to a huge cable

that lets me retract my keel when I find that it's length is too much for the current depth.
Still not buying it?
OK, it's early Spring, and the wheel was removed and stored on top of the cabin to provide more room to walk around in the cockpit.
That's my story and I'm stickin' to it.
