The difference between 5 and 8 wats would probably not be noticible 
under normal conditions but it may just make the difference between 
beinglost in the noice and being heard.

A vertical 1/2 wave dipole would be the obvious choice for a kayak. 
But the ability to have a strong signal from shore or camp seems 
important. Chances are, if your boat is capsized and flooded you 
antenna isn't going to perform all that well undewater.

A 160Mhz loop glassed into the fibreglass may be the answer though...
