Boat Sinking?????

ITD,

The poster who was on the boat stated that there was a "catestrophic failure...of the hull," and in a roundabout way blamed the marina/Cobalt Boats. It is unlikely that they hit something, as that would have been mentioned. The bellows theory was a good one as well. That sounds like a good idea as well.

A 1 inch hole is a huge deal. I forget the formula, but a two inch hole a foot below the waterline will take on about 70 gallons of water per minute.

Edit, here we go. I know this isn't the neatest, but it does provide an interesting reference. Source oceanmarineservices.com.
