re: Went to the boat for a sail..and its Flooded!!!

Good work !

Another argument for Bill Schock's " shallow bilge - strong hull" design philosophy. Bill recognized that cutting a hole in the hull diaphragm and creating a deep sump and then attaching a keel to the sump was flawed:

1) this is an inherently weak structural design with the biggest loads (keel) having plenty of opportunity for weak joints. The hull diaphragm is weakened by a big hole where it should be strongest.

2) big sump means needing to make the keel wider to fit a pump in there - wide keel = slow

3) big sump hides lots of water and lots of potential issues. Newport discovered a potentially catastrophic situation precisely because his S30 doesn't have a huge sump where water collects out-of sight out of mind. Newport found the root cause of the leak a d repaired it immediately because the shallow bilge hides zero water. Imagine if instead, Newport had a boat with a sump that held 15 gallons of water deeply hidden under the sole....he would not have know he had a serious leak until he would be outside !
