a. As numerous commenter have mentioned, the main comes down in seconds. No possibility of hang-up, even if done badly.
b. Sail weight means less on multihulls because we heel less. It does not have a negative affect on heel because it is always inboard of the lee hull
c. Multihulls are more likely to feather in a blast, and full batten mains feather much more comfortably.
