I have a 1997 Hunter 42, and am in the process of changing the anchor line and chain, I ahve noticed that the water does not completely drain from the anchor locker as the drain outlet is above the base of the locker, I have decided to put in a base made of slotted teak raised up a few inches to keep the line and chain dry. is there some reason that Hunter would have the drain raised up above the floor? Maybe there is a part that fits in there to keep the line out of the water?
