I am a bit overwhelmed by the amount of information from this thread.

I was kinda hoping for something like 'my 14ft cat had a similar mast,
so 82mm diam should be OK'.


Yes the proa is light. As a comparison Rob Denney's Elementary proa (1
person in cabin) weighs 110kg unladen. Proas tend to be long narrow
and light, disadvatnage is that thy do not have much space or carry a
lot of cargo.

The proa is a pacific proa, meaning that the outrigger (weighs 25kg
without ballast) is always to windward. At this point feel tempted to
give the mast a go becasue it is so cheap (is new and proper grade,
not junk), worse comes to worse loose $250 mast. As a comparison some
dingies with similar sail area have mast diam of 60mm in aluminium.
