I own an oday 322, the last 2 weekends we spent at a mooring there was clanking or banging that i assume are cables or lines inside the mast we are both light sleepers and never managed to sleep more than an hour on any of the nights, any 322 owners or anyone else have any suggestions as to what it is and a way to stop it, thanks
Noise from the mast

Wilf. Just a best SWAG, as nothing else to go by. In my mast there are electrical cables in conduits, Halyards. Also Halyards on the outside of the mast. Either or both of these lines could be the culprit for your clanging in the night.
More importantly how to stop this nightly noises with out ear plugs.
Try to tie the halyards off away from the mast. Use the bow or the side shroud bases as tie points. Or Tie off at the case of the mast but pull the halyard away from the mast with a tie or bungee to the shrouds.
Tighten the halyard so that the halyard inside of the mast is taut.
If it is the conduit (and it is possible) then you will need to take the mast down and reinstall the conduit. Most often the conduit is attached to the inside of the mast by pop rivets. These can become loose and every now and then need to be reattached.
Start with the most obvious (halyards). Good luck and good night.

To John's list, add the flags on the flag halyard. Amazing how much noise a burgee or courtesy flag can make while slapping shroud.
On my Mac25, it was the electric and coax cables flopping around in there. Ended up dropping the mast and ran 3 lengths of pipe insulation up from the bottom encasing the wires inside the insulation and taped them together with 100mph duct tape. Now I have the sweet sound of silence at anchor!
Another thing you can do for wiring inside the mast is to put sets of 3 zip ties around the wire right next to each other about 18" apart. Don't cut the tails, but orient them 120º around the wire. When you pull the wire back in the mast, the zip ties kinda push the wire to the middle of the mast.

Brian's idea works great as long as you have just the wires running inside the mast. Some have run wires through foam pipe insulation to quiet the banging.
If you have internal halyards they could foul on the many tails in a confined space of a mast.
Maybe the original poster could respond, telling us more about his mast and lines/wires.

Someone at the marina told me they knew a couple of people that had sprayed insulation expanding foam in their masts which stopped all the noise and the halyards still move, but certainly wouldnt want to try that because i would think your in major trouble if you have to replace a halyard or wiring

Wilf. Not a major issue. Just boat work which takes away from sailing time. Done all the time. Pretty much everything on a boat wears out and needs to be replaced sooner or later.
If the only thing in the mast is wires you could spray foam but you would only stop the banging at the bottom or the top of the mast. I would not take that path.
Better to get some long pipe insulation and run it on the wires all the way through the mast. You'll need to take the mast down, another task done from time to time.
Good luck.
