Yes, it's normal, at least in the sense that it's what happens if you don't take steps to prevent it. Others have outlined two methods. I'll add another, and many others here do this - use tractor pins to hold the spreaders in place, and unpin them from the sockets when the mast is down but before you roll it back (when lowering). Use a bunch of cheap ball bungies to secure all that rigging to the mast (Walmart specials).
Signaleer wrote:We tried to hand raise the mast, which we did. We have the adjustable back stay, which was completely loose.
"Completely" is open to interpretation. I disconnect mine. But I also use the old-style MRS, and crank down to make the forestay pin (more on that later). The leverage on that backstay is so good, and people are so weak, that even a loose catenary will make life difficult when attempting to pin the forestay.
Signaleer wrote:We could not get the PIN in the head-stay without adding a second shackle.

Bad, bad, bad. As already pointed out, that headboard shackle can easily open on its own, releasing the forestay, and dropping the mast without warning!

Danger, Will Robinson!!! You've attached the stem fitting (the thin attachment coming out of the deck, at the bow) to the anti-rotation strap of the furler! It's only there to prevent the drum housing assembly from rotating, and it's only held on by a couple of small machine screws. You're lucky it didn't rip off and drop the mast!!!
The round metal thing above that is the end of the tee-bolt turnbuckle screw. There should be a U-shaped piece of metal with three holes in it, one in the saddle that the turnbuckle tee-bolt passes through, with the U-piece passing through the anti-rotation strap, and then one hole in each leg at the bottom which pin to the stem fitting. This puts the load path of the forestay straight from the turnbuckle, through the U-piece (which is half of a toggle, actually), and directly into the stem fitting. The anti-rotation strap
takes no load other than preventing the furler base from rotating. You need to look for that part in the box of parts that almost always comes with a used boat, and if not there, call CDI and get a new one. Right away.

The upper and lower stays do not necessarily have the same tension when sitting at the dock. I don't recall which has more at this point, but I know they aren't the same. You need to adjust the rig yourself, starting with mast rake, which is controlled by the forestay adjustment primarily. The manual has the procedure, and I don't remember if the BWY procedure differs much from that.
Signaleer wrote:So, what do I do? Do I sail it with the second shackle? Something simply doesn't seem right.
Fix that forestay to stem fitting before you do anything! And if you don't have one, get or make a MRS, which will aid in standing the mast up (hard enough without one), and especially in pinning the forestay. But you can use the spinnaker halyard to help pull the mast forward to pin the stem fitting, which is what my MRS uses to raise the mast anyway. So I just crank down hard on it (5:1 reeving), pin the forestay, slacken it, and the shrouds are just right. Then I attach and slightly tension the backstay.
Oh, and the spinnaker halyard (the part in your left hand in the pic above) should pass between the legs of the forestay mast hound, so it passes straight down the front of the mast, wrapping slightly to either side as it goes, to a cleat. For raising the mast, I take the bitter end, after cleating, and tie it to the vang bail (belt and suspenders - if the cleat pops off, the mast drops).
Edit: Here's a link to the CDI page where you can download the FFII manual. It shows the contruction details, how to install, and how to use it. Especially useful is the cross-section on page 4 and the forestay sketch on page 7 which both show the toggle on the bottom (and top) of the forestay/furler and how it's attached.

Good luck. And don't hesitate to ask. Given what the PO has done here, I suspect you may find some other 'interesting' things that may need a little tweaking.
