Hi Nigel, welcome aboard.
I built the free DK canoe which takes 5 of us, however...
It's fairly basic, it's a bit heavy and although it's a very serviceable canoe it doesn't quite make it.
the wood working part of these craft is fairly basic, if you can use a measuring stick, a pencil and a saw you have it sorted.
The harder part is the resin, the filling, the filleting, the glassing and if you don't quite get it right the sanding, lots of sanding.
If you're a patient man and have a long car (this is relevant) I'd suggest the 18 foot Sasquatch

maybe the 16.5 one may work as the 18 foot dk is quite cosy with my kids as they are are 8 (twins) and 10, but it's a great picnicing boat
I'm sure you'll get plenty of advice

just remeber to just take the advice you agree with
