The funny thing is that some of the people arguing for bigger min weight for the cat (60kg) also wants the boat to be able to carry more weight.



grin Yes, I admit to that being true ! grin

And I thank you as you have still been to kind to me as I also argued for using aluminium components for dolphin strikerless beamsa and an unstayed mast using commerical alu tubing, Not too forget argueing for rotomolded hulls (possibly using twinex). All things that add weight to the design.

So yes, I do think it to be fair that I'm placed in the low-tech and heavier corner. Not argueing about that I'm afraid.



But on a different topic.

Have you weighted the new DS mast section already ?

I know the Pixie mast (timber/glass) you made came out at 8.9 kg. ; for I guess 6.5 mtr length.

The (strongest and stiffest) aluminium unstayed mast from tubing that I'm looking at (if it were to be extended to 6.5 mtr length) would come out at 9.85 kg with about 20% less moment of enertia with respect to forward swing during diving of the platform; so it is not too far off the Pixie mast (timber/glass) at all.
