"Ripley's legal claim that my husband and children are worthless is incredibly hurtful and insensitive," Coleman said in a statement. "Anyone who cares about people or has any human decency should boycott Ripley and their attractions."
One of the lawyers, Robert J. Mongeluzzi, said, "Ripley's inhuman legal ploy will sink as fast as their death trap duck boat did. We will legally and factually demolish this frivolous claim."

A spokeswoman for Ripley's could not be immediately reached for comment but told the Associated Press in a statement that the filing is "common in claims related to maritime incidents."
She said the goal is to give the parties time for mediation.
"We have reached out to those most impacted by the accident and offered to mediate their claims now," the statement said. "Mediation often leads to faster resolution and allows those affected to avoid a lengthy process of litigation, and most importantly, begin the healing process."
In July, the Springfield News-Leader — which like the Indianapolis Star, is a member of the USA Today Network — looked at the 1851 law, the Shipowner's Limitation of Liability Act, which limits damages to the salvaged value of the sunken vessel.
"The law was intended to bolster a fledgling maritime shipping industry," maritime lawyer Daniel Rose told the newspaper. "Congress was trying to encourage people to buy vessels and improve the maritime system. This was 1850, there was no insurance for maritime vessels. The incentive was that if you go ahead and buy a vessel, we're going to protect you if anything goes wrong.
"Fast-forward two centuries, it's still on the books. It comes up in every one of these major high-profile disasters."
Mongeluzzi said there have been no settlement offers. He is seeking $100 million in the wrongful death lawsuit involving two of the deceased passengers, including one member of the Coleman family.

The lawsuit alleged Ripley "recklessly risked the lives of its passengers for purely financial reasons."
Ripley Entertainment runs Ride the Ducks. Branson Duck Vehicles owned the boat.
Sixteen of 29 passengers died July 19 when a duck boat sank during stormy weather in Table Rock Lake near Branson, Missouri. A crew member also died.
Nine members of the Coleman family were killed: Tia's husband, Glenn Coleman, 40; daughter Arya Coleman,1; and sons Evan Coleman, 7, and Reece Coleman, 9.
At least 10 other lawsuits have been filed on behalf of other victims, including the five other Coleman family members: Horace Coleman, 70; his wife, Belinda, 69; his brother Irvin, 76; his daughter, Angela; and Angela's son, Maxwell, 2.
Ripley said in its court filing the boat was "in all respects seaworthy and properly manned." The boat, it said was "in good order and condition and suitable for their intended operation."
