Yellowknife, NWT Hull 1027, found online in an expired ad from YKTrader.com. "1953 Russel-Hipwell Steelcraft - Yellowknife Powerboats, Motorboats". Builder's plate seems to read hull 1027, length 35' beam 9'6' build year 1953. If you assume the broom is maybe 5 feet, those dimensions sound about right. It's an unusual design for Russel Brothers, but the hull number fits the 1953 year.
