For me the main benefits of a Harryproa, other than the proa benefits themselves, are:
Relative to a pacific proa, there is more weight to windward allowing a greater sail area to be carried; cruising proas do not wish to fly the windward hull but this is one of the main aspects of a pacific proa; the helm and crew are to windward of most of the spray whereas cruising pacific proas appear to be very wet boats indeed.
Relative to an atlantic proa, the main stresses are all concentrated near the centre section of the leeward hull whereas an atlantic proa has high stresses in the windward hull that have to be transferred to the leeward hull by a beefy beam structure; when an altantic proa gets powered up by strong winds the rig rises and this increases the overturning leverage whereas a Harryproa reduces the leverage marginally.
