See http://www.qcckayaks.com/kayaks/hulltodeck.asp. Is that a superior joint?

2. Looks superior to me. New glues are incredible powerful. How about this
joining method and a taped seam inside and out?

1. Here's a quote from your neck of the woods from Sisson kayaks (who make the
Nordkapp down-under):

"The hull / deck joins are cross-linked solid: All kayaks are joined within
hours of the original hull and deck lay-up. All kayaks are joined the same day
they are laid up using the same materials used to form the hull and deck. No
'bog' here! All boats keep their design shape - unlike other brands that are
joined out of the mould. All 'joined' kayak hull / decks are 'Post Cured' in
the mould.  This demands 'cooking' overnight with heat for optimised hull and
deck strength. Which means that the hull / deck unit is cross linked
(chemically fused - not just bonded) together into a solid unit.  This
sometimes means extra hours must be worked into the evening. No substitution
or compromise. Which means your kayak hull to deck join is the strongest in
the business."
