Hey downtownbrown, Yakima Racks is currently on a marketing blitz to promote their new Yakima ShowBoat lift assist for canoes and kayaks. But first go ahead and install a normal recommended Yakima multi-purpose base rack system on your 2006 Chrysler PT Cruiser roof top...
The Yakima Q Towers roof rack system is the solution for the PT Cruiser. The Yakima Q Tower system includes four Q Towers, two pairs of Q108 clips (these Q Clips are specific to your PT Cruiser) and two cross bars. You will attach the canoe carrier to the Q Tower front and rear cross bars. The 48inch cross bars are the recommended length for your roof top.
Then get the Yakima Gunwale Brackets canoe rack. It connects directly to Q Tower base rack front and rear cross bars. Four Gunwale brackets included and two heavy-duty padded straps included also. For total transport safety you should also get a pair of Yakima bow/stern tie down straps.
Finally, for your effortless canoe loading also get the Yakima ShowBoat Lift Assist. This system attaches to the Q Towers base rack crossbars and includes a roller that telescopes out over the edge of the rear of your roof to allow you to place the front of the canoe on it and then roll it into place on the Yakima Gunwale Brackets. Then you just retract the Showboat back into its storage position and you are ready to go! Please note that you will also need to purchase an extra set of Yakima 66 inch crossbars which are used as the extensions bars for the Yakima ShowBoat.
