In my Coronado 41's keelbolt area I have a lot of narrow channels that trap shallow pools of water. I hate having water around the keelbolts and mast step!
Have you considered building up some of the low spots with Epoxy putty or fiberglass? Obviously, you can't do it with all areas i.e., around Keel bolts, but it might eliminate some of the pools. I did this in my bilge to concentrate the water in one area and it works well.
