Lashing Liferaft w/Hydrostatic release
When attaching a liferaft cannister to deploy with a hydrostatic release we used 5 pad eyes. 2 on one side of the cannister and three on the other. Our raft was set in a cradle that lifted it about 6 inches off the deck. The lines from one side were led over to the other side just below the top of the cannister in a v shape and attached to the top of the release. The lines from the other side we led directly to the hydrostatic release on the shortest possible lead one line directly at the base of the release and the other two about 12 inches on each side. note be sure what ever arrangement you use the raft is securely attached to the boat to prevent it being washed overboard during rough weather. The deployment line was secured to a pad eye right next to the raft. I have also seen arangements where the lines met in the middle of the cannister. The key here is to make sure that if the release deployes the raft [usually when the boat is about 15 feet under water] none of the securing lines will foul its deployment. Remember that the activation line is probally 25'' long and the cannister has to exceed that distance from a sinking boat in order to activate the raft, the raft will have been released by the hydrodsatic release and then will be floating on the surface. You will need a weak link between the deployment line and the boat that breaks to insure that the raft doesn''t go down with the boat but is strong enough to cause the raft to inflate. I would also check with the manufacture of both the raft and hydro release for there recomendations. Hope you never have to use it.
