I'd be careful trying to swim very far off and ocean shore. I was
surprized once while swimming in the surf how far the undertow(?)
carried me away. I had to swim hard to get back to the beach. Dumb
tourist.

I'm a freshwater boater myself but I've read that a boat rising and
falling on ocean swells can drag it's anchor if the line is too short.
When a storm hit our exposed moorings at a local freshwater sailing
club a lot of boats dragged their moorings and those were large
concrete blocks.

I've got a sit-on-top which would have all the flotation I need and I
just need to jump back on, but the canoe, though it floats when
swamped, I guess I would'n care to bail out.

The canoe I only use in the Intracoastal, of course.
