One other caution that I forgot before is that your boat has to be properly shaped to accept the sheeting for a loose footed sail. The sheet now has to lead aft instead of vertically and it has to sheet outboard of centerline. It will not work if the stern does not extend a few feet beyond the clew of the main or if the stern is narrow. Many traditional double ended boats used a loose footed main and a boom on the mizzen because a loose footed mizzen will not work with their hull shape. And this all assumes that the sail is built for being loose footed.

The problem with getting rid of the boom has to do with sail shape. When sailing on the wind, this can be corrected by using the proper sheeting angle but off the wind, you won't be able to get the correct sheeting angle. As you fall off farther, you want to sheet the sail more outboard to keep it from bagging too much and this simply isn't possible. Think of it just like a big genoa. I suppose if you found a compelling reason to try this that you could work out a whisker pole for downwind sailing but at that point you might as well just use a boom.
I have sailed many loose footed traditional vessels and almost all have 2 sheets which is almost as dangerous as having a boom. Some boats with a single sheet lead the sheet to centerline which gives terrible sail trim. A traveler is pretty hard to get to work correctly without a boom although a rigid track one can work. Unless you get a traveler to work, you won't have a self tacking sail anymore.

|tager||The boom gives you greater adjustability, you have an outhaul. Reefing is simplified. Positioning of the mainsheet and traveler is closer to the helmsman. You could rig a sloop without a boom, but it would probably be more of a pain to get your mainsail setting right. In some conditions, you want a loose foot, and others a tight foot. The only way to acheive that without an outhaul is to have an entire traveler-grid instead of a linear traveler. That could become pretty complicated.|

You hardley ever sail a Hobie dead down wind without a spin. Usually they broad reach. This is thier fastest point of sail so the apparent wind is much farther forwrad than on a 30' sloop.
Keep in mind that loose footed and boomless are two different arrangements. Loose footed mains still have a boom, but the foot is not in a track along the top of the boom. It is only connected at the clew.

Cats can do it because of their width and speed. Some traditional boats with lug or sprit rigs are boomless. My Dory has a sprit rig that sailed boomless for many years. I added a boom for easier sheeting and better down wind shape. A great advantage of small boats (the dory is <19') is the ability to cheaply experiment with the rig.
The boom transmits much of the drive to the mast. Without it a 30' sloop would need mainsheet winches. It would also change the balance.
