Aw where to begin....Okay I'll take it from the top down with out numbers hope you can follow.
The origin of my response was to your comment,"Gaia's Dream is a Pacific proa which has been converted to a harry". Of which you have so kindly removed. My only thinking is so the context of my argument could easily be misguided.
My model with the logo of a square and then the name harry on it. Was placed there due to the way it looked with the easy rig and cabin top only. it made sense. As I made sense as to how to make model work and changed things around substantially getting model to work to my liking I changed the name. As to the hulls, they were design on my computer full size then scaled down. All my models are built this way paying close attention to weight, displacement, waterline draft, to name a few things etc... To most, my models seem/like look/like toys but knowing the thought process of how and why they are conceived they are more than just what they seem, to most.
The thing is I get the look of your shunting craft and the name.
Just Like I get Piver, Corsair, Wharram, Newick, etc....What I don't understand is where do you get off saying Gaia's Dream is a Pacific proa which has been converted to a harry"? Can you explain did I miss something.
I never mind sharing as long as what I'm sharing isn't put under a classification to define someones name or design.
Next thing I know With statements like Gaia's you just might assume every shunting craft with beam hung rudders and a wing sail Is a Harry too.
Last statement of your retort about steering issues on shunting craft, asking me "to be more specific"? If you reread my post on the other forum it is specific.
