A year ago I restored a 12' Huron. Following repair to the hull, new decks & thwart, oil & varnish to the inside, paraffin to the outside, with no outwales, this hull weighed 30 lbs. on a scale I had at home. Canvas was stretched, traditional silica-based filler applied, sanded, primed, then multiple coats of paint, and the outwales & brass stem bands put on. This canoe went to Assembly and was weighed on Mark Zalonis' scale and came in at 48.8 lbs. So this comes in close to Benson's 15 lb. guesstimate.
