Liferafts like everything else can be
cheap or expensive... And should not be compared to by
price but the type of use and construction.
We had a guy in
San Francisco Bay that we trusted (Sal's Inflatables, Alameda).... He walked us through the various liferafts in his shop from Viking to Switlik.
I was surprised at the huge difference between the rafts construction, from
cheap seams to overkill.
We also had a friend that had a experimental
catamaran sink on him half way between
New York and London. He was floating around for 39 hours before a freighter rescued them.
We had another friend who was in the
water for 3 hours after loosing her
boat to a whale strike of the coast of
Baja California. While deploying the liferaft, a wave washed over the
cockpit and took their water proof ditch bag over the side with a spare
VHF, water and
food. hey were left with what was inside the liferaft.
We were planning ocean crossings when we first started cruising and went with the Switlik SAR-6 for our
boat. It is the same raft the USCG drops from their helicopter during rescues.
Yes Switlik is expensive, but if I have float around in the middle of the ocean for several days, I wanted something that would hold up to the extremes. The supplies inside the raft always worked at the repack dates and we supplemented the initial provisions at the first repack, doubling the water and
food.
So with that in mind, my recommendation would be to consider what will you be using the Liferaft for. If you are sailing in Bays, Near Coastal or
Blue water. Then start thinking how long will it be for help to get to you.
With that information you can decide which raft is appropriate for your type of sailing situation.
