Definintely not a boat guy, but last time I was near the water I saw a cruise liner take off, I noticed the lifeboats were more like 'life capsules' .. they were completely enclosed and (total speculation from that fact) presumably some kind of 5-point harness for the passengers so capsizing overall isn't really a danger.. Passengers would just spin around a while until conditions improve, and the boat will right itself from whatever ballast it does have.. since the goal of the lifeboat isn't to 'go' anywhere, it doesn't need to be so upright as to support a sail like here..
