Funny you should ask...
Jason,I have a '79 Cat 22 swing keel with the original trailer. It was specifically built for the Cat 22 - it has the appropriate bed built for the curve of the hull, and guides to ensure that the keel ends up center mass as the boat is recovered.It was in functional condition when I bought it. But it in no way inspired great confidence. I made the needed fixes to make it road worthy, but still faced the real decision of - grind/sand, fix, prime, and repaint - or buy a new one. As Trail-Rite made the trailer I called them first. They have the ready ability to make a new trailer for your 1972 swing keel Cat 22. You cannot get it through the company, but you can through any boat dealer that works with Trail-Rite - the catch is the price tag. I want to say (it has been a year or so) that they wanted $5000 for a new trailer. In a way, that does not seem unreasonable; on the other hand, I paid $3000 for the boat/trailer combination in the first place. The real decision comes from what do you want to do with your boat? My trailer meets my current needs - winter storage, haul in and haul out. But if you want to do the "true" trailer sailor thing - and start taking extended journeys, then I think it is prudent to have a good, mechanically sound, trailer specifically designed for your boat. Hope this helps. SJK SENDS
