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:
““... Ain’t it a caution to us not to fix
No limits to what rose in rubbing sticks
On fire to scare away the pterodix
When man first lived in caves along the creeks?”
“Marvelous world in nineteen-twenty-six.””
—Robert Frost (1874–1963)
“Mathematics alone make us feel the limits of our intelligence. For we can always suppose in the case of an experiment that it is inexplicable because we don’t happen to have all the data. In mathematics we have all the data ... and yet we don’t understand. We always come back to the contemplation of our human wretchedness. What force is in relation to our will, the impenetrable opacity of mathematics is in relation to our intelligence.”
—Simone Weil (1909–1943)
“Predatory capitalism created a complex industrial system and an advanced technology; it permitted a considerable extension of democratic practice and fostered certain liberal values, but within limits that are now being pressed and must be overcome. It is not a fit system for the mid- twentieth century.”
—Noam Chomsky (b. 1928)
