Boaters: Beware of Hazards!

Safety Tips Available from Sea Grant


By John Karl

MADISON, Wis. (6/30/98) —  As summer steams along, many boaters are enjoying the splendor of the Great Lakes. When boating on these inland seas, it is important to remain mindful of potential hazards, including lightning, commercial fishing nets, and—even in summer—hypothermia.

Three free Sea Grant publications can help you maximize your pleasure and minimize the dangers of boating on the Great Lakes:

For copies, contact the UW Sea Grant Communications Office, Goodnight Hall, 1975 Willow Drive, Madison, WI 53706-1103; phone (608) 263-3259, or visit one of Sea Grant’s Advisory Services field offices at UW-Milwaukee, UW-Green Bay, UW-Manitowoc, and UW-Superior.

 

 

Lightning at Sea

"The most important safety rule about lightning and boating is simple: Get off the water immediately," said UW Sea Grant Water Safety Specialist James Lubner.

"If you are unfortunate enough to be caught in a storm on the water, stay as low as you can in the middle of your boat, and do not touch any metal parts of the boat or any electronic equipment that is attached to antennas," Lubner said.

Commercial Fishing Nets

Many nets are set with two buoys on a line perpendicular to shore. The buoy closest to shore will have two flags, and the buoy farthest from shore will have only one. Because it is often not possible to see both buoys, boaters should pass on the shore side of a two-flag buoy and the sea side of a single-flag buoy.

"Boaters should also remember that they can not tie up to any buoy they find," Lubner said. "Only mooring buoys, which are white with blue stripes, can be used for tying a boat up."

Hypothermia

 

Survival Positions in Cold WaterDuring the sultry days of July and August, hypothermia may be the last thing on your mind. But even July water temperatures in the Great Lakes are low enough to be life threatening in as little as 30 minutes, according to UW Sea Grant Water Safety Specialist James Lubner.

"Water temperatures lower than 80 degrees Fahrenheit can cause quick reductions in body temperature," Lubner said.

The surface temperatures of the Great Lakes can be much colder: mean temperatures in July range from 43 F (6 C) in Lake Superior to 72 F (22 C) in Lake Erie.

"And upwellings of cold water, which are fairly frequent near the leeward shores of the lakes, can reduce water temperatures to 50 or 60 degrees Fahrenheit. At these temperatures, you’ll get real cold real quick," Lubner said.
