Police are trying to figure out what caused a crash between two boats on Kootenay Lake last weekend.
Around 3 a.m. Saturday a 16-foot Sea Ray rear-ended a 19-foot pleasure craft.
RCMP Sgt. Monty Taylor says the time of day might not have been the only factor.
Four men and two women were checked out at hospital but only one suffered a minor injury requiring stitches.
It happened opposite Nasookin Road.
