Leaving a boat or backing out might be more of an issue... too shallow you may have to push it but I think the verge between the two or the last one before swimming is just fine.

Note that if area is more open to sea storms may batter it against rocks etc.

Ah ok, I'm not using this channel necessarily as a parking spot though, its just a cut-through of a thin strip of land that separates the ocean from a big lake thats close to my home. Could just dock there but it'd be long cart trips to-and from the spot across the lake where I'm digging the channel.
