Back in earlier days, I owned what we called here a Maxi Trailer Yacht. It was called a Gazelle 26. I loved it, and it was extremely seaworthy, as when the keel, (electric winch driven up and down), was locked down, it was in effect, a keeler. They race then across Cook Strait in NZ where it was built. I got it as the manufacturer's own demonstration vessel, so beautifully set up.
However it was heavy to tow around, (2 tonne loaded), and I often wished the Macgregor 26 had come out a bit earlier, as the concept of being able to take on - or drop - water ballast was so amazing. That and the fact with ballast and rig furled, with a 50-60hp outboard, the thing could plane at 20kn..! I suppose with the rig removed, it would save quite a bit of kerfuffle launching and retrieving, but I think I'd want to preserve the sailing capability, as I did miss that when we went trawler style. Not having to have a wet berth, and associated costs of anti-foul etc sure has its attractions as well.
