I am about to take delivery of a new 400 fly. During our sea trial and poking around, I noticed what seemed to me as a large amount of water in the bilge. It was about 4-5 inches deep and the water was even visible in one of the forward hatches (floor of aft cabin). I asked the dealer about this and they said maybe it was because it had just been washed. This does not make sense to me as everything topside should drain overboard. That being said, I am coming from only owning outboard boats (Boston whaler, Grady white, Pursuit) so my bilge usually never had any water at all. What should I be expecting with regard to quantity of water in the bilge?
