. . .Horseshoes are difficult to use in the water and hardly fit around a normally dressed thin person, never mind if wearing bulky waterproofs and tubby . . .
They've changed over the years. More to reduce manufacturing/transport etc. costs than any deliberate change in safety thinking, I would think.
The standard current ones are compact, very lightweight and come in nice colours. I doubt you'd get more than an arm through them, which then calls into question why not have a long rather than a U shape.
I have an old-fashioned lifebuoy that came with a previous boat. It is larger overall, and narrower in section, so the opening inside is significantly larger. It is also solid, not soft/flexible and much, much heavier. (It might well knock you out if it landed on your head!) On the other hand, it would much easier to throw a distance or into the wind, and be much less affected by wind both in flight and once afloat on the water.
