When I was in school, it was said that the only stupid
question was the one that you didn't ask, and I was always the one
who asked the questions other children were embarrassed or afraid
to ask.
This may have been asked here before.... If so please forgive
my re-asking it. What is the rationale behind having two unequal
length hulls on an HP. This is a signature feature of Rob's
designs, as is the cabin in one hull, and the Aerorig, and the
multiple rudders, all for obvious reasons. The reason for the
long slender hull under the mast(s) is not so obvious to me.
I can close my eyes and conjure up an image of a
"TikiProa", with one or two free standing masts in one hull of a
wharram, and a cabin on the opposite hull that extends out over
the bridge deck, and the "Dennyrudders". I know of no
catamaran of any kind that has a single mast in one hull, nor have
I heard anybody make a case for why it would not work. I've
toyed with the option of having a mast in only one hull on a
catamaran, versus a biplane rig or central mast (all free
standing).
At first glance the photo below looks like the mast is in the
near hull (stbd) and unstayed..... it clearly is neither. The
sterns have less freeboard than the bows, but that's a trivial
issue. It isn't much of a stretch of the imagination to turn this
into a "tiki proa".
