Ive got a better solution to the canoe problem...
similiar to don's but does not require drilling for the artificial rain gutter
and is bombproof !!

the thule "super high foot" ( i think model #972?) attaches directly to the
raingutter of the westy, and clears the fiberglass top!  you can also move
them if necessary.  you will NOT find this as a fit in the thule manual.  REI
carries this rack.  I carry my old town on it as well as two bikes !! ( i got
three bars, two over the luggage rack for the bikes and one way in the back to
tilt the canoe on to, then push it up...perfect.  With the canoe carrier it is
simply great !!
