Oh swimming is hardly the issue. Literally wheeling to the water through sand is the issue.

I have the technology

The technology is as simple as buying a beach wheelchair with big fat tires that don't get stuck in the sand. I still don't know how I'd get into the water though. Might have to crawl rofl.

Can u even swim without using your legs?

Sure, although there is the issue of my legs sinking down. I've heard of people using water wings around their ankles to keep them afloat lol. Otherwise your feet drag on the pool or ocean floor, which would be like sandpaper after awhile (or worse if you're going over a coral reef).

I've actually swam before, but it was like in the month after my major neck surgery, so I couldn't really enjoy it. Still had to wear a neck-brace at the time, so I couldn't even breathe like normal lol. If I did it now that I'm healthy I'd probably enjoy it.

Been like 11 years since I've been swimming come to think of it... shame I've never tried since then... I used to love swimming. I used to be on the swim team as a teenager. I was good at it, although I never applied myself and would routinely finish 2nd. I'd also skip meets (partially because my parents were apathetic about driving me an hour to get there). I was a terrible teammate. The coach hated me.

You need to go swimming again good sir, whether it be at a pool or beach, seems like you might miss it more than you think

Can you just float ?

Get a mobi-mat bud. We have beaches here that have ramps that go right into the water you can roll right out there.

Well I'm definitely not going to be carrying all that to the beach lol.

Get a friend.
