Re: [harryproa] sculling

G'day,
Sculled well is an exageration. They scull. Never tried them in tandem as
I am usually solo. Far better performance was got sitting on the beam and
paddling, better again, sculling , better again would be a dedicated Yuloh
type set up.

Nothing at all on schooner rigs, until we see how Elementarry works. Still
think they will be harder work, (sheeting), heavier, more expensive and not
as good to windward, but would love to be proven wrong.

None of the masts needs the stay anymore, except maybe to control the bend.
So, I would suggest unstayed.

Regards, (and thanks for the help with that kiwi clown)

Rob
