so still discovering about my boat and this line brings up several questions. Should you figure out what rate of flow if you were to lose one or two or three of your thru hulls? so that the bilge pumps will keep up to what may be coming in? I have a 900gph johnson and a manual as back up. I only have 2 X 1/2 " intake; 1 X 2" out for head
; 2 X 1.5 " for instruments. Not a mathematician but with all less than 1.5' below water line (less depth
, less pressure?) does anyone know how to calculate if pump out matches or can over come water in with drastic all thru hulls leaking? Obviously, hitting something large enough to put major hole in hull
, prob last thing you are worrying about is capacity at that time. life jackets, crew and radio
alert then fill/fix the hole and then see if pumps can keep up? would be my concern at that time.
