Length of Mast Yard and Boom

Hello everyone,

I'm very glad to have found this forum! I'll directly start with apologizing for my not-so-great-english, originating from the fact I'm living in Germany ;) I started building a GIS, everything fine so far, except: The mast-length seems to be 4730mm according to the plans, and the yard an boom about 3600 each. But then why is it said in the timber-list that I would need the timber to be 5700mm for the Mast and 4700 for yard an boom? Are these just typos (and if yes, which one is right?) Or am I missing something? Maybe there is a super simple answer to this and I'm simply blind or dumb?

Anyway, any help is appreciated :-) All the best, Peter

Peter, I'm sorry nobody got back to you, but I don't see those numbers in the plans. The first set of numbers you posted is pretty much correct.
