Does anyone have info on whether twin bilge keel yachts are less ocean-capable or ocean-worthy than single, long-keeled cruisers? Does self-righting affect them differently?

In theory a long keel yacht will have more stability due to the leverage of the keel.
In practice so many twin keel yachts have crossed oceans that they speak for themselves.
A twin keeler will in some cases roll less than a long keel going downwind due to the reduced pendulum affect.And the damping effect of the two keels.
There are poorly designed long keelers and twin keelers so you would get more usefull information if you enquired about a specific boat .
The old type twin keelers had vertical keels which made them poor to windward in a blow which in my opinion is a major seaworthiness issue. The modern type with splayed out foil shaped keels are far better.

Chay Blythe tried to circumnavigate singlehanded in a bilge keeler early in his career, and was forced to give up when in the southern ocean - a problem he blamed on the inherent unsuitability of bilge keels for that type of sailing. One of his books discusses this in detail.
Interestingly though, the same class of yacht (Kingfisher) was handicap winner of the Single-Handed Trans-Atlantic race around the same time.
Draw your own conclusions!

don't think he even got as far as the Southern Ocean - didn't he give up in the Atlantic and pull in Cape Town?
