In addition to the 6 PCs, the lifeboat has Kes, Warren, Ohen and the two Horarians. They are not old or very young and appear by their words and look to be Shelleshe, not Yinite. They introduce themselves as Yuri and Kamato.
There are enough supplies for 20 days you guess, but it is harder to say without Sorel here as he was trained and had experience in this.
The boat has some damage from when the other knocked it into the water, but nothing that prevents it from safely floating.
