Not much of a Sailor myself, but 20 years in the Navy
as a Parachute Rigger (PR)
I can see the possibilities here. Below is a copy of the information from the website.
The trick with flying this sail is to make sure that none of the lines get tangled. There are 28 lines on our parachute, 18 lines to the top and 14 lines to the bottom of the sail. When we bring the sail in we always tie the two sets of 14 lines separately and make it ready for when we want to launch it again. This makes your job of setting the parachute very easy. You also want to set your parachute so it doesn’t get tangled with anything on deck
. We normally set our round parachute over the side of the boat and then set up the parachute and our course once it is launched. As for taking the parachute down, this is the part that most people dread when it comes to flying their spinnaker downwind. There are a couple of ways you can get your parachute down. We use our genoa
. By rolling out our genoa
the parachute comes in the lee of the sail and you can easily pull it in on deck
Might be a typo, but, a standard 28 foot flat chute has 28 shroud
lines that have 4 quadrants of 7 lines each. By joining two quadrants together you would have 14 lines each. The write up states 18 lines to the top and 14 lines to the bottom, hmmm, that's 32 lines. I would think that a modified flat canopy that was incorporated in the Navy
chutes many years ago would work better. This modification was used to allow the user to somewhat steer the canopy. Four panels
of the chute were modified by removing a portion of the the panel, thus allowing air to "spill". If these panels
were positioned at the bottom while deployed on a sailboat, seems like the top portion of the chute would fill better and reduce rotation.
Just a thought.
