Thanks for the info! I have been doing a local table here, a combination 
from several sources, plus a table including the effects of wind. I am 
going to publish the material in our club?s magazine next week, and in 
the national Paddler magazine (Finland) next fall.

The problem with the tables is, I think, that we do NOT know the eccects 
of all variants: body fat, mental and physical health, clothes, wind 
etc. beforehand.

Shawn, I think a table will always include some marginal because of 
these variables.

Two kayakers in a double capsized few months ago at Baltic Sea close to 
the Aland Islands. The older guy, father, stayed concious in water for a 
full hour before they were rescued. Against all odds: water was + 1,5 
Centigrades, wind 8 m/sec, waves up to 6 ft. The wind makes the temps at 
the skin get low down to -10 to -13 degrees Centigrades, quite a lot 
below the freezing point...

Unbelievable. He did not have a dry-suit, but neoprene shorts and a 
paddling jacket plus loose rainproof trousers. Some woollen and thermel 
underwear. Neoprene gloves were unuseful after few minutes because of 
the wind, I guess.

Stay safe, you guys!

Cheers,
