Where the size for the ODay302 asymmetrical is specified.
Rigging an asymmetrical is also available as the 302 is rigged pretty much the same as a Catalina 30 or a Cal 35. Or pretty much like every mastheadsloop made.
You need a Spinnaker Halyard preferably on a mast Crane.
A tack sheet that can be run to the cockpit to adjust.
Finally 1 or 2 sheets to control the sail. These run outside all of the rigging to the stern. Then you turn the sheets into the cockpit using a block. You secure the sheets using a cleat or a clam cleat.
Enjoy the sail. They are a lot of fun.

Here is another site that has sailsize info. I don’t know how accurate it is but yet another place to start.

I’m not sure what you meant by “roller furler”. Perhaps you already know this
but the tack of an asym can be attached numerous ways.
1) Ideally the tack is connected to a bowsprit
2) A connection via the existing hardware on the bow (anchor roller etc)
3) Something like the ATN tacker that lets you use your furled headsail.
There are asymmetric furlers typically called “top down” that let you douse and deploy the sail.

If your bow roller is securely attached to your boat, then it might be usable. That is what I have used.
I adding a length of shock cord to raise the tack block above the anchor on the roller.
Bow sprits are nice. Not absolutely necessary.

I have used the ATN tacker and found it was a good solution for me for what I was trying to accomplish. The boat I had at the time came with a symmetrical spinnaker with spin pole etc. I realized I didn’t have the skill or enthusiasm to rig all of that for singlehand use so I bought the ATN device. It worked OK in light wind but I was always a bit concerned when the wind got stronger or the sail would rapidly inflate. Lot of force in one area of the forestay.
Notice in the ATN video there aren’t any whitecaps! There are a number of threads on here about how others have connected to their bow roller or added an aftermarket bowsprit.
I would also suggest you think about how you will be using the sail, number of people to handle it etc.
This type of sail is really a lot of fun and can turn a downwind slog into a challenging sailing adventure

Note that the ATN Tacker is not a tack attachment as it does not hold the tack down to the bow. Its purpose is to control the location of the the tack near centerline but you still need to run a line down to a strong point with a block attached. I attached to my anchor pin.
Attachments
Just mind the possible line chafe to the furled foresail with that position.
Enjoy the spin, and douse before the wind pipes up!

That might not be a problem for the ATN but the “logic” is to have all of the attachment points “forward” of the existing bits leaving enough space so the flying sail doesn’t snag on something.
If you think of the upper and lower attachment points for your forestay/headsail, the deck and the mast forming a right angled triangle ; you need to have the flying sail “connected” farther forward than the existing hypotenuse of that triangle.
If you don’t have it “forward” you could potentially launch your new flying sail but then have it wrap around, catch the existing bits and have a scary mess to deal with.

Hunter 216 spinnaker inside or outside gybe preference
Jackdaw I rigged a wand as you suggested (using an old windsurfing batten off a formula sail) about 5 feet long. I just used Velcro wraps to hold it on as it was a light wind day but will likely tape it on to the sprit in the future, as I could see that any serious wave action at the bow would...

You might try our method: I take one wrap of the rack line around the top rail of the bow pulpit to windward and forward of the vertical support, then secure the snapshackle on the toe rail. If I attach it in rail hole closest to the bow, the tack is free so the spinnaker can lift up and belly out when the wind is aft of the beam. If the wind is forward of the beam, and I need a tight luff, I pull it down, and attach it farther aft on the toerail.
