There are 3 main racing classes in the sport to-day concentrating on smaller and lighter yachts
than in the past. These are called Class 3 and Class 5. Both types of yacht use 'lift' generated
on the wing shaped sail to travel at between 3 and 5 times the wind speed reaching speeds in
excess of 60 mph.
Class 3 yachts are the fastest and most competitive. Most are commercially built with aerofoil
'wing' masts and slim enclosed glass fibre bodies.
Class 5 yachts are smaller, open, and of tubular construction, with pole masts. They are built
to rigid specifications either commercially, or for the home builder from approved plans.
