We have the ‘Fiord Explorer’ which is a bit heavy but takes two. I took it down the Seaforth River in Fiordland afer a 3.5 day hike in! For a one person boat you could try the ‘Alpacka‘ or the ‘Scout’ (if you are as small as Della). These boats will handle any water you would likely dare. For calmer water there is a lighter cheaper craft the ‘Flytepacker‘ @ 35oz (997g). You can get a durable paddle as light as 23oz (650g): http://flyweightdesigns.com/product/flytepacker/
