Hi All,

I have been researching multi designs to build for a while now (Wharram, Woods,
Kellsell,
Shuttleworth & Farrier) and really like the Harryproa concept. It just seems to
me that there
is not much space in them for their size. So I have a few questions regarding
their design.

Why does the accommodation hull need to be so narrow down low? Could a Harryproa
be
built with an accommodation hull like the centre of a trimaran, or at least more
flared.
There would be little more wetted area, but bouyancy would be improved as would
living
area inside. Is it because of slamming or wake interference between the two
hulls?

The bridgedeck area from what I have read is not of standing head room height.
Could the
height of the mast boom be raised to allow for more height in the bridge deck or
would
this adversely affect windage and or righting moment?

Could the lee hull be flared more at the top to provide more useable bunk space
when
visitors are aboard or for crew if the boat were put to charter work?

Sorry if these have been canvassed before, it's just I couldn't find the info.

Love the designs, just love the simplicity, keep up the good work.

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...

G'day, The booms are bonded to the masts, so the main sheet is only altering the angle of attack, not tensioning the leech. Therefore, the winch size is what...
