Docks?

So I came back home yesterday to my raft gone. I figure it was damaged (maybe bashing against the land?)

I built a dock kinda - it is in an elongated squared off U shaped - stairs up to the bottom section, then like, 5 floor sections out. There's just enough space for my raft to fit.

I suck at sailing still and have problems getting the raft in there.

I saw someone make a dock that's basically straight to the water, then stairs down into the water. They dropped their boat.

Is that good enough to protect my raft or boat? I think that would be easier to sail up to, rather than trying to fit my raft between some dock planks.
