[Paddlewise] Resistance & Displacement

Would anyone know the effect of adding weight to a kayak on the energy
required to paddle it.  That is, if I double the weight do I  double the

work I do?  Is the effect proportional or something very different?  I'm

fairly new to kayaking and the web, and brand new to paddlewise.  If
this is discussed elsewhere, I'll go looking.  I did look at John
Winter's KAPER formula, since both resistance and displacement are in
it. But between my rusty math and ignorance of boat
terminology I could not figure the answer to my question.

Thanks.  Brian Heath
