Quarterback Daunte Culpepper and three other Minnesota Vikings were charged Thursday with three misdemeanors each for taking part in a bawdy boat party earlier this season on Lake Minnetonka. Culpepper, Bryant McKinnie, Fred Smoot and Moe Williams were charged with indecent conduct, disorderly conduct and lewd or lascivious conduct, according to court papers. If convicted, each player faces up to a maximum of 90 days in jail and a $10,000 fine on each count. Prosecutor Steve Tallen's decision was based on findings by the Hennepin County sheriff's office, whose investigators reviewed allegations of lewd and drunken behavior aboard a floating party Oct. 6 that involved some Vikings players. Crew members complained that some people took off their clothes and engaged in public sex acts during the cruise, according to Stephen Doyle, an attorney representing the boat owners, Al & Alma's Supper Club and Charter Cruises in Mound. The crew members identified 17 Vikings among about 90 people on the two boats. The court papers released Thursday said Smoot and defensive end Lance Johnstone arranged the charter. Smoot declined comment in the team's locker room before practice. Both Culpepper and Williams are on injured reserve and in rehabilitation on their own, away from the team. McKinnie wasn't seen in the locker room. Vikings coach Mike Tice was careful with his reaction. "According to NFL rules and union contracts, there is a large difference between allegations and charges and convictions," Tice said. "So until at any point there is a conviction of some type, if there is, I have no action to take and nothing to say."
