BURLINGTON, Iowa (AP) -

An Indiana man said he paused his trip down the Mississippi River after his kayak was tampered with this week in Iowa.

John Hatch is from South Bend, Indiana, and began the journey of about 1,600 miles with his friend Larry Humphrey on Aug. 1 in Red Wing, Minnesota, The Hawk Eye reported. The trip is to help raise money for breast cancer research.

"I've had some friends go through it, and I wanted to challenge myself," he said.

Hatch continued the trip alone after Humphrey peeled off this month in Clinton.

He said after paddling for 28 miles on the river on Monday, he docked his kayak at a Burlington port. He returned the next morning to find his boat eight inches deep in water.

His sleeping bag, first aid kit and other equipment were ruined, Hatch said. One of his hatch covers is missing on his kayak.

He said he had to call Humphrey from five hours away in South Bend to pick him up.

"This is nothing major," he said. "You can expect certain setbacks. This is just an interruption. When I start again, I'll start from here and continue on."

Hatch's goal is to reach New Orleans by October. He said he will reassess if he can reach Louisiana by then once he finds new hatch covers and replaces the other equipment.
