I did a lot of research on the Mac 26 (I was looking at the M) before deciding on a bigger boat. The Mac trailer is nothing special, except you have to check where the bunks rest on the hull. I think you would have to remove any rollers that may be installed for the bottom of the "V" due to the centerboard on the 26X.
You may be able to find a trailer for the Mac....I recall seeing a website that sold new, aluminum replacement trailers (dual axle I think) to better handle the load of the 26.
