The Tennessee Senate has unanimously passed a bill to improve safety at Tennessee marinas.

The "Noah Dean and Nate" bill requires marinas to have ground fault breakers that automatically shut off power if there's an electrical leakage. If it's signed into law, marinas would also have inspect its equipment annually and post signs warning people about the risk of electric shock near docks.

The bill is named after 10-year-old Noah Dean Winstead and 11-year-old Nate Lynam.

The boys were swimming near two houseboats in Cherokee Lake on July 4, 2012, when the electrical current entered the water.

Investigators say a faulty electrical cord on one of those houseboats is suspected to have caused their deaths.

The bill now goes awaits a House vote.
