Hi Paul,

You have read my mind. I did asked Ms. Vivier the question and in fact I have just received back his reply:

Hello Carlos,

Thank you for these pictures.
Yes, it is better to increase the mast diameter to 80 mm if it is built with the bird mouth method.

Kind regards

François Vivier Architecte Naval

I did some research on the web and wrote down in my notebook that the mast diameter should be increased, but now that I starting that task I was trying to double check but could not find where I got this idea from. Mysteries of the web.

I’m also an engineer, not as lucky as you are now, but in 5 years time I expect to have as much spare time as you have now!!

One last question: I scaled my pieces and got 3 kg for the oars/ea. 3,5 kg for the yard, and 4,5 kg for the boom. Yes, that last one is a little bit beefier than the drawings suggest… but 1,5 Kg, is that serious?

Birdsmouth… yes, the internet have made inconscious people like me believe the can make all sort of stuff. I’m a subscriber of the off center harbor website, and everything seems possible… I will try.

Best regards
Carlos Herrán
