Limits
In the beginning the F18 class rules functioned as a template for the F16 class rules, but not much later the two rule sets started to diverge. The F16 class focused more and more on a truly lightweight design with a reduced rule set. The latter meaning that all rules governing a particular minor detail in the boat design, like the minimum weight of a rudder board, were dropped. The F16 rules control what is known as a 'boxrule'. Eventually a reduced number of major limits was finalized:
- Maximum overall length is 5 m.
- Maximum overall width 2.5 m.
- Minimum overall weight 104 kg 1up and 107 kg 2-up .
- Maximum mast height 8.5 m.
- Maximum mainsail area (including mast) 15 m².
- Maximum jib area 3.7 m².
- Maximum spinnaker area 17.5 m².
The other main rules are:
- Mid height width of spinnaker is at minimum 75% of length foot.
- Boat must be rightable by crew either solo or doublehanded without external assistance
- The rig may not be trimmed between start and finish by means other than sheet, downhaul, outhaul, traveller, mast rotation and halyards systems.
- Only "soft" sails are allowed.
- No ballast other than corrector weights up to 7.5 kg are allowed

Famous quotes containing the word limits:
“Yet shall he mount, and keep his distant way
Beyond the limits of a vulgar fate:
Beneath the Good how far—but far above the Great.”
—Thomas Gray (1716–1771)
“And when discipline is concerned, the parent who has to make it to the end of an eighteen-hour day—who works at a job and then takes on a second shift with the kids every night—is much more likely to adopt the survivor’s motto: “If it works, I’ll use it.” From this perspective, dads who are even slightly less involved and emphasize firm limits or character- building might as well be talking a foreign language. They just don’t get it.”
—Ron Taffel (20th century)
“The limits of prudence: one cannot jump out of a burning building gradually.”
—Mason Cooley (b. 1927)
