[Rhodes22-list] Soul of the sole - and Stan's info

I have a '93 and for most situations, including frequent trailering and
beaching, it is stiff enough.  But I sail on Lake Erie and wanting to sail
in more than ideal conditions presents additional challenges for the R22.
That's because of choppy waves.

So after various cracks appeared, I have a compression post to strengthen
the mast step and a wood longitudinal stringer reinforcing the front edge
of each cockpit bench seat.  The post isn't in the way and actually offers
a nice hand hold.  The stringers fit flush underneath the seats and don't
interfere with storage, but the stiffer seat takes away from the signature
cockpit comfort.
