If I put my whole list on here I'd need my own forum.

Fortunately I know that between sailing, home, sailing and work I won't get to much of if.
Fortunately it's warm enough that I can sail year around here, although last January when I overnighted at 13 deg, sailed next day with a high of 21 and overnighted again at 10 deg I began to wonder if was actually warm enough.
I just returned from a couple of weeks sailing around the Outer Banks (Pamlico Sound and Onslow Bay), where I put a 5" - 6" crack in both rudder cheek plates from excessive force whilst surfing. That's getting fixed next week. Also fabbing a new bracket for the spare tiller so that it's ready to go.
The ol' girl's looking a bit shabby, but weather's turned cold and wet so will probably delay painting until spring.
Flexed up the hull/deck enough that several portlights again leak some. Need to fix that.
Installing an anemometer and masthead antenna before I raise mast again. Fishfinder / depth sounder died at the coast, as did the tiller pilot. Replaced the finder, but will send it for repair so as to have a spare. Planning to install the new transducer, too, so that I have redundancy there as well. Also will wire the chartplotter into the VHF so that DSC calls can include lat/lon.
While the 1/4" steel "U" extension I had fabbed worked just fine on the coast and permitted me to tilt up the new Tohatsu easily, I'll do a prettier job on extending the motor mount.
Need to install the electric choke on said Tohatsu to get the full benefit from remote starting.
Resealing the bow eye, since it seeps a bit in large waves and dampens the V-Berrth.
Replace carpet in V-Berth area, with insulation underneath, and recover the forward sole.
Install a second bilge pump forward, and a manual one in the cockpit.
Install a meaningful latch on the companionway hatch and drill the drop boards for pins so that I don't have to tie those down when sailing in rough/puffy stuff.
Install a new stereo I purchased from Cambridge Soundworks -- max draw is 1.5 amps and it kicks ass-- long live the batteries!
That's the "short" list. Long list of wannas, including installing cabin edge toe rails / sail tracks, installing opening portlights that I already purchased, additional fans, some lighting changes, galley improvements, new mattress in VBerth and QBerth, improved electrical panel and combiner, opening up some additional storage, installing an anchor roller that doesn't interfere with trailer launch / recovery and some miscellaneous control refinements, but realistically most or all of those will still be on the list rather than the boat come spring.
The biggie I really need to get to is removing the swing keel shoes and pin and quite probably having new ones made (I'd like to add about 100 - 200 # of ballast to those shoes if I rebuild them, and fair the keel while it's removed). That smacks of a long, drawn out effort filled with unpleasant surprises and expletives, and frankly I dread it; because I push the boat hard and am ranging further, though, I probably need to do it.
I'm also considering a second C26, fixed keel, to keep on the coast, but am hard aground on that decision, since getting the boat up to my standards would be quite time consuming and expensive.
