I took a look at the boat drawings in Peter's web site and it looks like he
tried to think of everything.  He had buoyancy tanks but it does not say if
he had foam flotation or just air.

>From a boat design strandpoint his keel could use some improvement. A lower
aspect ratio keel that incorporated water tanks would keep the boat floating
higher in the event of a serious leak while still making it self righting. I
cannot think of a good reason for a high aspect ratio keel on this kind of
boat. A longer shallower keel would probably provide better directional
control, greater resistance to broaching and reduced roll and pitching. A
longer, shallower keel would also improve the structure of the hull. I think
the boat would have also benefitted from more beam and less length. He would
never paddle at speeds where the length would pay off so a wider boat that
would have lower wetted surface would have improved his efficiency .

Probably not fair to criticize too much without knowing more but these
things popped into my mind as soon as I saw the drawing.

Cheers,
