The length you need is the I measurement, since the mast is stepped on the cabin top. 6071mm. The rigger will need to figure out what might work for you. Maybe a Lightining mast. Maybe he has a boom from a bigger boat lying around that would fit the bill. Do the sails have slugs, slides, or just a luff rope? Each detail makes a difference. That’s why you need to find a rigger.
