Tough new penalties for people caught boating under the influence go into effect this Sunday.
A BUI will now be classified as a gross misdemeanor, punishable by up to a year in jail and $5,000 fine.
Before the change, those convicted of BUI faced a maximum sentence of 90 days in jail and a $1,000 fine.
Boaters suspected of operating their vessels under the influence will also be subject to taking breathalyzer or blood tests if an officer finds probable cause.
"If you refuse to take the tests or give the blood sample, you can be cited a $1,000 fine," said Sgt. Kevin Haistings with the Seattle Police Harbor Patrol. "There's also an assessment that goes on all traffic fines. In this case, it's 105 percent."
That means on top of the potential $5,000 fine and jail time, BUI offenders could get slapped with a ticket for $2,050.
In addition to alcohol, officers will be looking for those suspected of excessive marijuana use. The legal limit for alcohol is 0.08 percent blood alcohol level. For marijuana, it's five nanograms.
