The white donut is cheap and unlikely to be stolen. Unlikely to "break" or degrade. So it makes a cheap and reliable way to throw something RIGHT NOW to the guy who just went overboard, while you're within 50' of them.
On the downside, white is unsafe since whitecaps are white and the ring will quickly be invisible in any rough water. So it is useless for marking the trail back to a MOB, or making the MOB more visible.
Still, it is cheap and reliable if you bear in mind it just isn't as good as other equipment, which comes in high visibility colors. A can of spray paint, a couple of coats and clear overcoats to slow the UV fading, can improve that for $10.
