Hi Banoe
Shes stable sitting on the bottom,I havent installed a seat yet but I will keep it low (for my daughter)I prefer to kneel as I think it gives You more control(please remember Im no expert)
No oilcanning whatsoever as the floor has a slight vee shape.
There is a few build options,well three!!! all 6mm taped seams,4mm sides and 6mm bottom taped seams or all 4mm with fiberglass cloth,I used option two.
Sorry I dont know how much she weighs(we are all skinny in our house so we have no scales!!!!)but i can easily lift Her above my head,if or more likley when I build another I would have a chat to Matt about thwart position and install a centre one and have two sort of grab handles close to the breast hooks(for hull stregnth),this would make slingging Her over your head an easier task with the centre thwart.
I will try and borrow some scales from a neighbour and weigh the girl(please keep this info confidential as we do not want to upset Her

)
There is a supplemental step of adding a skeg to the stern,I am thinking of adding it for my daughter as She is new to canoeing, I love the manouverability of the Eno but other people may like to add it for tracking
Matt does state on the plans to try the boat out first and see how You go.
What sort of river is the Adrondaks ?
Hope this helps You out a bit.
All the best Zeb
