This will be our first year on the hard w/ the mast up (but we will get shrink wrapped). Any thoughts on releasing some of the rig tension? I'm thinking about loosening up to just a little more than hand tight.

What say ye?

No, you don't want to relieve the tension and allow the standing rigging to shift and sway and deteriorate over the months of repeated wind stresses it will withstand, IMHO.

I am not a fan of storing on the hard with the mast up. I feel that it places unnecessary and extra stress on the rig, fittings and hull because the boat can't heel in response to the force of the wind as it is intended to do. Also if you are stored on a trailer that isn't tied down high winds can topple the boat. Boats have even been known to shift in a cradle because of high winds.
But if you must store with the mast up I agree that the rig should not be loosened.

I would loosen it a little. No need to have it hard as if you were sailing in 30 knots of breeze. I always slack my backstay when in the slip.

If it is hard, it is just pulling up on the deck.

Just to stir the pot a little more... I left mine tight when I stored with it up. I suspected the shock-loads of a loose rig would cause more stress and wear than than wind pressure against a bare pole (with no boom). (Likewise, a boat on a mooring with wave action should have a tight rig.) Of the hundreds of boats I've seen stored with masts up in the marinas I've been in, complete with winter nor'easters, I never saw one go over. But YMMV...

Somebody taught me to tightly spiral-wrap the halyards around the mast to prevent "mast pumping"--it supposedly creates some turbulence that disturbs the harmonic action. I can't vouch for the result, but I wrapped the halyards during the winter. Pumping is also a sign that your upper shrouds might be a little <i>too</i> tight. I eased mine just a little when I felt the shaking while on board in my slip one windy day.

Exact same thread exists on Sailing Anarachy.

Always a good question - bottom line, ask what others in your yard do. In our yard, winter storage with the mast up is financially "encouraged". Nearly every boat is stored on a cradle and the vast majority are covered. We shrink wrapped our boat the first season but thereafter cover it ourselves. The time and effort to build and install a frame for a winter cover is minimal and the cost savings is huge. We remove the boom, as well as the lower shrouds, both fore and aft and loosen the uppers by 1.5 turns. I bungee wrap the shrouds and halyards to the mast as high up as I can reach and again at the base. The adjustable backstay is relaxed but not slack. IMHO you do not want your system overly tight while on the hard. Our storage frame is built from a couple of 2x4 ridge beams and 1x2 rafters lashed to them. The sides are steep enough to shed snow easily and its tall enough that I can begin cleaning in the spring before the cover comes off. There are many variants to this; many use plastic water pipe arched over the top of the boom.
