built H28s were all masthead sloop
rigged. The original wood boats were ketch
rigged. I think John Lidgard, a well known Kiwi designer/builder did the design modifications to update it to make a halfway decent production fiberglass
boat, if I remember right the mods included raising the freeboard by 4", a larger cabin
, a sloop
rig and maybe increased draft
. There is a wood ketch in a friends yard here that is probably going to be cut up if no one wants it. The compass glass boat has vastly more interior
space than the wood one.
It is a fallacy that a full keel is more stable, it is not, but it may track straighter than a fin keel boat at the expense of maneuverability.
