on Anomaly. Both are large roach square heads made from mylar and strings (which doesn't have a very nice "hand"). The main is 960 sq ft and 24' on the foot.

While I sometimes swear at the Stackpack, I don't think I could do without it. The main is on recirculating ball batten cars, I flake the halyard carefully and let it rip at full speed to drop. As long as I am head to wind, the sail will drop into the Stackpack, maybe with just a few bits hanging out. The mizzen is only 215 sq ft, piece of cake even though the mizzen overhangs the transom and the aft end is hard to reach.

The placement of the lazyjacks is important, both to contain the sail coming down and also to not interfere too much with the sail going up. The batten ends will try to catch on the lazyjacks early in the hoist, you have to be careful until the shorter ones are clear.

On my boat the main stackpack was redone three times, each time trying to get it lower and more compact. The first version was quite large and in keeping with their normal practice. It was the easiest to use, large enough to contain the sail almost completely on a smart drop. But the boom on my boat is already about chest level, that made the stiffening batten on the Stackpack more than shoulder height, so it was nearly impossible to straighten out the sail for a nice harbor furl or zip the cover closed. The second iteration was lower, still plenty of room in it and still too high. The third was lower still, this time with the stiffening battens moved down the pack a little bit as well. The stiffening battens are what you have to reach over the do anything with the sail. I like the third iteration the best, it has two benefits: the stiffeners are below shoulder height so I can straighten or work on the sail, and the closing flaps from there to the zipper bulge up a bit from there to cover the furled sail. This latter means that the pack collects less water, most of it runs off rather than pooling in the valley. However because the sides are lower, it does not contain the sail quite as well on a messy drop.

If you are going with the stack pack, I would take a look at the sailplan, measure your shoulder height standing next to the boom, and make sure the Stackpack batten is going to be about 6" lower than that. It can come right up under your arm with some inconvenience, but above that it really gets in the way. I believe the Mackpack has no batten, so you can pull it down between lazyjacks and get in there, not true of the Stackpack.

I take both sails off with all battens installed and the Stackpack zipped up. They are like a big sausage, get it onto the dock then remove all the fiberglass and reflake to brick and store.
