Tom,
That, a 17 ft'er, would be a lot more likely.
Sommers over time bought 122 (or 123) canoes, all were the 17 ft model except one, which was a 18 ft vee model. You'd of remembered the vee if that was what you paddled.
Joe built 6 - 18 ft double end canoes, 4 went to Rom's canoe outfitting, the other 2 went to Widji.
Widji, bought or was given (donated) about 50 canoes, starting with the 16 ft models, a few 18 ft'ers and finally and mostly the 17ft'ers. They likely have something in excess of 50 Seliga's in their fleet now, plus they are now making 1 or 2 new canoes a year, built by the campers under the surpervision of the canoe masters.
