Test drive them
Jack,See if you can find someone to let you take some of these boats out. Help them step and unstep the mast.I spent almost a decade "rigging" C25's for a dealer in the 80s. I would recommend something a little smaller if you plan on trailering the boat much. Stepping and tuning the mast, then dropping it to haul out is a bit of a pain for just a weekend. I don't know your physical condition, but it's definitely something to consider.As far as the swing keel is concerned, if you're going to sail in shallow waters, it's very useful but there are sacrifices, performance being the biggest. It's another potential point of failure to be watched (primarily the cable - inspect it frequently). Unless you're sailing w/ the keel partially lowered, hum from the cable shouldn't be an issue. Just give it some slack. Most of the C25s I worked on were swing keel. Of the Catalina fleet at the time, I believe these were their worst performance-wise. The tall rig makes up for it some, at the cost of trailerable convenience. A fixed keel makes a big difference. I don't have a lot of experience w/ the H25. My brother had one, but I don't know what year. It was a solid boat. It seemed to sail better than the C25s. Catalina makes (or made?) solid boats. When working for the dealer, someone brought in a C22 that they had been towing from NY to FL, when the hitch separated. The boat on the trailer passed them on their starboard at about 50 knots, hit a gaurdrail, and rolled over. A few stanchions were bent, and the companionway hatch was damaged, but the hull and deck looked fine. We sent it to our glass shop for a thorough inspection, but it certainly wasn't coming apart. Not sure sure that'd be the case w/ some other production boats I've sailed.
