out we deliberately loaded the stern of her boat while leaving the bow
light.  She said that this made a positive difference (I think we may have
inadvertently been putting too many water bottles into her bow since it has
that convenient hatch that is easy to open on the water by another
kayaker).  This would be similar to leaning back, basically shifting weight
to the back of the boat.

Since a lot of the hills in north east Kansas were formed by glaciers
during the last ice age some of the rocks around here are probably original
CBR's.  Would there be a problem using the original CBR's or have there
been significant improvements in the last 10,000+ years?  :)

Trimming down at the stern shifts the Longitudinal center of area aft. A
better method than adding weight would be to attach a small fixed skeg aft.
I have found that something a foot long and tapering to about 2" deep works
wonders. Such a skeg doesn't add a lot of resistance and can serve to
protect the bottom from abrasion. If you mount the skeg just aft of
amidships (about 10% of the waterline length) it can reduce weathercocking
without hindering maneuverability much.

I do not recommend using Genuine Canadian Ballast Rocks (TM) for trimming
the boat. They should only be used as directed in our very complete users
manual. >
