Also, a
windsurfing board which is longer than 320 centimetres and having a volume of not less than 200 litres. Longboards have a
daggerboard besides a fin, which other
windsurfing boards don't. The main functional distinction between longboards and
shortboards is that longboards are meant to be used in a non-
planing (displacing) mode.
Longboards are mostly used for learning to windsurf and for relaxed cruising in the sun. It's possible to learn to ride a longboard in 1-3 hours, given appropriate conditions and a good teacher.
