Lifting the boat with one strap on the keel won't hurt it

This particular C22 has a swing keel. It's attached to the hull with
only a pivot bolt. I don't think allowing a strap to put pressure on
it would be a good idea.

Not to worry, if you think of the normal and expected loads it is
designed to handle, such as groundings. But you can mark "straps here"
on the side of the boat to help avoid the possibility.

Step and unstep the mast on the water as the shrouds will probably
get in the way of the hoist.

I agree but one reason he wants to keep his boat at the club is so he
can keep his mast *up* on the trailer. ............. granted, the
mast is easily raised and lowered. Especially with quick release
shroud fittings.

Take a good look at a rigged boat. Imagine hoisting it, turning it to
the water, then lowering it in, all supported by a single cable. The
shrouds will easily get in the way, particularly as one strap will be
ahead of the mast, one behind.

The lift operator(s) will probably already know how to do it right.
Ask them.

At a yacht club?? Typically, the lift operator will be the boat owner
himself..... except maybe on regatta weekends (aka Chinese firedrill
.... might not be the best time).

Then ask around for the most experienced member -- after the race,
perhaps plying him with a favored libation.

BTW, if you have keel bolts like the Tanzer 22s, they bolt a lifting
bridle to two of them that the hoist can just hook to.

If it had a fixed keel, that'd be the best way for sure (J22 comes to
mind). Unfortunately, this boat is a little different. Mounting
lifting eyes would be a design challenge and involve structural work
strengthening whatever you mounted them to (maybe one through the
cockpit floor and one through the boat bottom in the swing keel slot?)
Once you had it figured out, it'd beat straps though.

Have you looked in the bilge? (Apologies if you have) The Tanzer 22
came with either fin or swing keel. Both bolted on. Wouldn't be
surprised if the C22 was done the same way.
