NORTHSTAR MANUAL20• Your boat has normally self-bailing system. Water collected in thedeck will automatically drain out of the boat through hullfittings.Please check hoses periodically.9.4. STABILITY AND BUOYANCY• Any change in the disposition of the masses aboard (for examplethe addition of a fishing tower, a radar, a stowing mast, change ofengine, etc.) may significantly affect the stability, trim andperformance of the craft.• Bilge water should be kept to minimum.• Stability is reduced by any weight added high up.• In rough weather, hatches, lockers and doorways should be closedto minimize the risk of flooding.• Stability may be reduced when towing or lifting heavy weightsusing a davit or boom.• Floatation in your boats hull.• Air tanks shall not be punctured.• Breaking waves are a serious stability hazard.9.5. WEATHERYou should never leave the dock without first checking the local weatherforecast. You can get the weather information from the TV, radio, local,newspaper, on-line, or from one of the weather channels.At certain times of the year weather can change rapidly and you shouldcontinually keep a "weather eye" out. While you are out in a boat here area few signs you can look for that indicate an approaching weather change:• Weather changes generally come from the west. Scan the sky withyour weather eye, especially to the west.• Watch for cloud to build up, especially rapid vertically rising clouds.• Sudden drop in temperature.• Sudden change in wind direction and/or speed.• If you have a barometer on your boat, check it every 2 to 3 hours.A rising barometer indicates fair weather and rise in wind velocity;a falling barometer indicates stormy or rainy weather.9.5.A. WHAT TO DO IN SEVERE WEATHER• Reduce speed, but keep just enough power to maintain headway.• Put on your PFDs.• Turn on running (navigation) lights.• Head for nearest shore that is safe to approach, if possible.• Head bow of boat into the waves at about a 45-degree angle.• Keep bilges free of water.• Seat passengers on bottom of boat near centerline.• If your engine fails, trail a sea anchor on a line from the bow tokeep the boat headed into the waves. A bucket will work as a seaanchor in an emergency.• Anchor the boat if necessary.
