Now let's look at liferaft positioning and mounting:
By far the best answer is a purpose-made locker in a place that makes deployment relatively straightforward. Great to say, but if our boat did not come to us so equipped, and most don't, hard to do.
For the rest of us, where to mount a liferaft is one of those annoying problems with no perfect answer, since pretty much every option has drawbacks.
The Worst Position
For example, on most boats the easiest position to deploy from is the cabin top, since the raft can just be skidded over the side without lifting it, but that's also the most vulnerable position to being washed overboard, and on most boats results in a hit to visibility from the cockpit.
Given those two problems, Phyllis and I would not stow a raft on the cabin top. After all, it would be upsetting to end up in the liferaft because our boat was sunk by a collision due to the blind spot caused by the liferaft!
The Best Position
So with the cabin top rejected, what's left?
