Use Your Head!

A lot of heat escapes from your head. A hat helps keeps this heat in. Steve Burke  

Layers Of Warmth

Several layers of thin clothing keep you warmer than one thick one. They're more flexible, too, if it warms up as you can always take one off. Steve Burke  

Forget The Diet!

Eating keeps you warm in cold weather. A calorie is actually a measurement of heat. Steve Burke    

Safety First!

Always wear a proper life-jacket when you go out in a boat. A foam buoyancy aid is not a life-jacket, just an aid to keep someone who can swim afloat in sheltered water, and only then when wearing lightweight clothing. Steve Burke    

Be Prepared!

Always carry a spare tip ring, a lighter and some hot melt glue. If you damage an intermediate ring whilst fishing you can carry on but with out a tip ring you're stuffed! Budgie
