Yes

Yes many times

I live 2 mi/3.2 km from the English channel. I've lived close to the sea my whole life. It would feel strange not having it close by.

many times

Many times. I'm about 2 hours from the beach

Yes, rode around Newport Harbor in California a few times in a peddle boat, lots of fun. I want to get a sail boat and head out to sea, maybe spend my days just island hopping.

I live a block from it, but the trees are in the way. I can still walk there though.

of course, many times. i live within walking distance of the ocean, actually.
