What can you do to stop the spread?

It's simple: clean, drain and dry



If your boat has ballast tanks, an inboard motor, or other raw water systems (A/C, shower), the required dry time is always 30 days.

If your watercraft does not have any of the above systems, the dry times are:

  • Summer: 7 days in June–August
  • Fall: 18 days in September–November
  • Winter: 30 days in December–February
  • Spring: 18 days in March–May
