It would be wise to keep a knife or line cutter
handy to the rear cockpit
in any event. We keep ours under the cockpit
table in a scabbard. (Some people keep a machete there for other reasons). You would not want to rely on a quick release buckle as the sole means of releasing your life raft (they would still need to be maintained). When offshore
it would also be wise carry a clasp knife on your person as well. I reckon those webbing straps could be cut in a couple of seconds, and with all the Adrenalin going around deployment would not be an issue as the raft is hard plastic shell on slippery stainless bars. So if a knife or two is/are available why spend the money
on something unproven?
