Companionway cockpit "step"

We have a similar bridge deck as in your picture. Not only does it provide extra seating around the cockpit table, it provides the perfect spot for a night watch under the sprayhood. We have all the instruments grouped around the companionway: plotter, sailing instruments, VHF, autopilot remote, so we can stay in the shelter for most of the time, and stick our head up from time to time to have a good look around. Night watches have become a lot less tiring in this boat.
Difficult to climb over? No, if we are getting difficulties with that, moving on deck would be really dangerous, so it would be time to give up sailing.
 
I can't believe that so many people do not seem to realise that this is an important contribution to the seaworthiness of the vessel, reducing the risk of downflooding. Because sailing craft are relatively slow and cannot always run for shelter it is important that they can cope with adverse conditions they might face, not merely those they expect or habitually encounter.
 
Some replies show that unfortunately my thread was not very clearly understood. Probably my mistake as English is not my official language. OF COURSE all boats must have something to stop water entering into the boat from the cockpit. But the majority of the boats have simply a raised fiberglass part where you simply need to raise your foot on top of it (from the cockpit floor) to reach the companionway steps. In the boat examples I have listed, you need to actually step up into this part (sort of "step") before reaching the companionway steps. In a long trip this can be annoying for some. For others it can be an extra space to sit.
 
Like many terms, ‘bridge deck’ is rather elastic. It is often defined as a ‘raised separation’ (https://en.wikipedia.org/wiki/Cockpit_(sailing)), but a longer (fore and aft) raised section which you call a ‘step’ is often also called a bridge deck - perhaps fairly, as it does provide the higher barrier to water entering from the cockpit well. (Both uses are secondary anyway, as a ‘bridge deck’ in primary nautical usage is the deck area bearing the helm and navigation station.)

I’m no expert, so I may bring down on my head the wrath of those who are, but I hope that helps.
 
My boat has big 'step' - I'd call it a bridge deck, it's great for safety as mentioned, .

That looks incredibly dangerous. To get to & from the cabin to the cockpit one has to walk at high level , exposed to any wave that may sweep the deck.
To clear a gybing boom one would have to be bent almost double & I can imagine one coming on deck & not being entirely aware of what is happening on deck.
