Naturally, the canister is better protected than the valise. However, if stored properly, the life raft is equally protected by the canister and the valise. We recommend storage in the canister because generally a valise is not stowed where it should be. Often the valise is stored in some kind of locker seat where something else might be placed on top of it that could damage the raft. In addition, the canister is attached to the boat while the valise is not secured to anything. If an emergency arises and the raft is still thrown overboard, it is then useless. This happened to professional sailors in the Fastnet Race in 1979.
