Formula 16

The Formula 16 (F16) sport catamaran is an ISAF recognised 5 m long beach catamaran with an asymmetric spinnaker setup.

It is actively sailed in two modes: doublehanded with a jib (2-up), and singlehanded without a jib (1-up).

Its class rules setup is very similar to those of the Formula 18 class of beach catamarans.

In effect any boat that adheres to a certain limited set of general design specifications may participate in all the official class races. The two classes, F18 and F16, govern the racing of their own class compliant boats.

The F16 class was founded in the spring of 2001, after it had become clear by the overwhelming success of the F18 class that formula classes would be the future in sport/beach catamarans and that a more versatile formula class was desired.

In handicap racing, the F16 uses a D-PN of 63.0

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:

The other main rules are:

The F16 class was from its inception engineered towards a dual-role sports catamaran with certain remarkable qualities. A careful balancing act between the major components of the F16 boats allows this result.

The result being that the same craft is used for both doublehanded sailing/racing as singlehanded sailing/racing; the craft has a very similar performance in both modes (doublehanded and singlehanded); and the F16 boats share as good as identical performance with their intellectual parent, the Formula 18 class.

Several modifications were made to the early F16 class rules to achieve this result. The founders believed this result to be important to the growth and success of the F16 class. Additionally, both the doublehanded and singlehanded F16s race each other for being first across the line as well. They are simply that close in overall performance around the race course.

The other goal that the F16 class was engineered towards was the ease of handling the boat by any singlehanded or doublehanded crew. By far most sport catamarans are designed for use in only one mode, either as doublehanders or as singlehanders, which makes flexible use of these boats cumbersome and in some cases even risky, as quite a few boats require the combined effort of two crew to right it after a capsize. This design goal forced the F16 setup towards a generally smaller and lighter setup so that an average-sized solo sailor can both handle the boat well while sailing and when taking it out of the water and onto a trailer. By increasing further the lightweight character of the design and incorporating several technological advances, the boat could again be made to perform well when sailed by two average-sized adults. In this respect the F16 class had found its own unique character and has set itself apart from its mentor the F18 class.
