I would have to agree that Grady Whites can be "unseaworthy" because
mine sank:

The photos on this website are of my Grady White Marlin 28. She is a
1990 model and is equipped with twin Yamaha 250 Sal****er Series
outboard engines. She also has a four stroke 9.9hp Yamaha kicker motor
and all of the fishing gear that you could ever dream of. I purchased
the boat at the Seattle Boat Show in late January of 2004 from a local
Grady White dealer, Jacobsen's Marine in the Ballard area of Seattle,
Washington. She sank seven months later on September 3, 2004 while
fishing with my father at the mouth of the Columbia River. Within
eight minutes of leaving the safety of the harbor in Ilwaco, Washington
the boat had slipped enough water through a cracked open seam in our
splash well to fatally condemn our trip. The experience was absolutely
terrifying as my father who is in his eighties and I crossed the
Columbia Bar, the "Graveyard of the Pacific", in a sinking boat. Worse
yet was not knowing why the boat was sinking. Even worse than that was
the response I received from both the dealer, Jacobsen's Marine and the
company, Grady White of North Carolina. In the near future, this
website will provide more photos, details on how My Grady White Sank
and marine safety considerations that will certainly make your boat
safer.
