In terms of mast raising and lowering, The catalac
is the easiest to do this on your own. However this is not the whole story, lowering with the pivot t the tabernacle is simple, but this leaves the mast significantly unsupported and sticking out astern. You need to lift
it forward about 2.5m. I have done this on my own when I was younger, but this is not for the faint hearted!
Another problem is that this position will raise the roof line by about 6".
You will also have the mast sticking out ahead and astern, and will need to remove the shrouds and backstays
I believe you need to re-think your overall plan.
Operating a catalac 9m on the canals is not impossible, although the width may cause a few problems in passing other boats on the canal.
operating in the estuary with an occasional movement into the max height area is also possible, but would be easier leaving the mast ashore.
I believe that the method of operation proposed would soon become a real pain in the *************.
I dont have a solution, but believe you have to understand the problems in order to find your own solution.
