Think Ice

By Lloyd Roberts
  • This book by Lloyd Roberts and Warner St. Clair is THE definitive book on DN building, tuning, racing and sailing. Mainly about DN iceboats but relevant to all iceboaters because it covers safety, clothing, how to load the car- it’s all in here! Updated with instructive commentary by many top-flight iceboat sailors. Order your copy from the Chickawaukee Iceboat Club in Maine.
