I have never heard the word Skymaze before, but if it is the hinged, keel
system, popular in Freo and Perth, I have been using it for well over 20yrs. I am not at all interested in going under bridges, but it gives a keel
which cannot leak and I would not own a yacht without it. As I have said a few times before, the only moisture I get down below is on my beer
can. If it were discussed as a keel stepped mast system ( rather than a bridge negotiator ) which CANNOT leak, I reckon it would sweep the world as a mast mounting method.
There was a post relatively recently about the system and bridges, so you should get some replies pertinent to bridges.
All the best.
