One of Robs many innovations is the leeward facing bridge deck cabin
that nearly always provides shelter from the wind.

    I'm not sure that the sail on an HP or HP style boat need always be
to leeward....... It should be possible to tack or shunt with equal
facility, depending of the design of the boat.     On a long passage in
the tropics, one might choose to have the sail to windward to direct the
breeze into the cabin instead of sheltering the cabin, or perhaps one
might choose weather to have the wind to port or starboard based on sun
angle for shade or warmth.   In mild conditions, the choice of port or
starboard tack might be based on comfort criteria rather than rigid
sailing criteria of always having the sail to leeward.   I'm the kind of
guy who might change course for a few hours on a long passage  just to
get the sun out of my eyes, or tack downwind to eliminate the constant
rolling on a monohull.   Being comfortable is more important to me than
making the fastest time possible to the next tiki bar with scantily clad
barmaids and umbrella drinks.   If we are always in a hurry to get from
port A to port B, that suggests that most sailors don't really like
sailing..... they'd rather anchor in a crowded anchorage or park in a
slip in a floating trailer park. To me, sailing is about being at sea...
If I'm in a hurry to get someplace, I'll fly!
