DN Iceboat AS All-Speed Mainsail

Heavy air, clean ice

The North Sail All Speed sail is designed for heavy air and clean ice. It is powerful enough to accelerate the boat off the line, but then it rapidly flattens out to reduce drag. Keeping the class girths at maximum helps to reduce lee helm at high speeds, thereby providing greater control and less chance of spinning out.

Standard Features

  • E-glass battens
  • Three full battens
  • RBS rocket adjusters
  • Flex-cord luff rope
  • Two large windows


  • Carbon batten upgrade
