Re: Rig Design questions

Thanks Rob,
The steerability in shalow water is a good point

snip


. The other big advantage of the schooner is that you can trim the
sails individually to steer the boat, which is particularly handy if
you have no way on and are near head to wind, or in shallow water.

In shallow water with little or no rudders down , can the boat still
point. I would assume that in spite of the shallow draft, the lack of
rocker would still give good tracking.


I read recently, I think it was in the Australian Multihull World
talking about the Wide Bay bar, about a cat pitch poling from surfing
in and digging its bows in the sand. I was wondering about how the
lack of rocker on a Harryproa would fare in similar circumstance. I
am tossing up between; better as the lack of rocker means lower COG
nad earlier and gentlerlift and acceleration; and worse as the bows
would dig in sooner. Overall I feel it would fare better from a wave
overtaking and worse if you overtook the wave and surfed down its
face.
Any views after taking Elementarry through the surf?
Robert

Hi Richard, If you have been considering an F32 then the Visionarry would seem cavernous. Trimarans are fine craft but relatively expensive. They also have one...
