Thanks for your replies!
I went "whole hog" and bought a used 25# CQR, and with the chain, I figure that's 40-50#. So at a quiet mooring I tried a trial of lowering it over the stern/out of the cockpit into ~30-40' of water, and then bringing it back up again.
Whew!
I put a rubber mat I had on board over the gunnel to protect it so I could drag the rode/chain over the gunnel and "put my back into it", because just leaning over the side and pulling it up wasn't gonna happen.
And thinking of carrying all this forward, then carying all this aft-either I'll hurt myself or the boat, I'm afraid. That's what keeps me from installing a bow anchor roller-
I hadn't thought about hauling it up through the forward hatch, and then lowering it back down there afterwards-like you say, that doesn't sound like a lot of fun, either. And my under-V-berth "anchor locker isn't big enought for the CQR, so then I'd be lugging it inside to the companionway and up to the cockpit locker...
So I'm thinking about a stern roller for dropping and retrieving the anchor, (though still running the anchor line off the bow when anchored)-either permanently mounted on the gunnel or mounted on some sort of plank with that temporarily lashed to something aft.
Thanks all for giving this a read and your consideration!
