To drop the mast and keep the boom attached you need to raise the stern mast holder so that there is room between the mast and the cabin top for the boom, we also have a support between the mast and the mast baseplate.
We tried it all ways for the first year or so but this works much better both in security against and convenience especially when launching.
Note it has travelled like this for tens of thousands of k's now with no problems, the raising of the mast carrying points is adjustable at the rear for when camping with the mast down but even in the lower position it's still much better when moving around the cockpit with the bimini able to be used as an extension of the boom tent making all the rear of the boat covered or at least in shade.
It also means that the spreaders are above the lifelines so that you don't have to maneuver them out.
Not a good picture but it shows all the points including a button on the boom cover missing which was lashed closed after the picture was taken.
