Hi

I want to fit a kneeling thwart just aft of centre in my Wenonah Adirondack
kevlar tandem canoe, for soloing.

I realise we'll never be talking perfection here as the boat is failry wide
in the center section. However I don't enjoy soloing the canoe 'backwards'
from the bow seat so much as I don't want to rely on carrying ballast.

I'd ordered the boat with a center seat, which rests on two non adjustable
aluminium angle brackets suspended from the aluminium gunwhales and riveted
in place. Although I jacked the seat up and angled it with wedges, it was
never far back enough in the boat for my liking.

My carpentry skills are somewhat limited and as the boat has slight
tumblehome, the higher I fit the kneeling thwart the more I'll have to shave
off the sides as it gets narrower.

So, in order to minimise the 'chopping and changing', what is a reasonable
starting height for fitting a kneeling thwart, measured from the bottom of
the boat? (The Adi has a fairly flat bottom and hasn't yet oil canned.) I
am 182 cm / 5'11" tall.

Any advice much appreciated.
