That assumes you had the presence of mind to deploy it as you were ejected. A ladder in the boat does you no good when you're in the water.
BTW, water sucks heat from you 25 times faster than air of the same temp. Being in cold, moving air while also being wet may be miserable, but nowhere near as miserable as being immersed.
