Looks like fresh paint on the bottom already. If the bottom paint is "Anti Fouling", I would think the boat is going back in the water in the next few days or less. Normally, when that type of paint is used (at least in salt water) the boat is relaunched very soon afterward while the paint is still fresh, otherwise the "Anti-Fouling" properties are diminished/lost if the paint drys out thoroughly.
Then again, maybe the paint is just ordinary enamel.
NB
