Formula 16 (sailing)

Formula 16 (sailing)

The Formula 16 (F16) sport catamaran is a 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 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.


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. Eventually a reduced number of major limits was finalized:

*Maximum overall length is 5 m.
*Maximum overall width 2.5 m.
*Minimum weight (ready to sail) 107 kg.
*Maximum mast height 8.5 m.
*Maximum mainsail area (including mast) 15 m².
*Maximum jib area 3.7 m².
*Maximum spi area 17.5 m².

There are a handful of additional limits that regulate, for example, the maximum length of the spinnaker pole and the ability of righting the boat singlehandedly without additional aids.

Design goals

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 father, the Formula 18 class and boats.

This means that F16 boats, in either mode, will race their F18 example on a level basis. Several modifications were made to the earlier F16 class rules to achieve this result. The founders believed this result to important to the growth and success of the F16 class. Also both the doublehanded and singlehanded F16's race each other for being first across the line as well.

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 double handers 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 to right it after a capsize. This design goal forced the F16 setup towards a generally smaller and lighter setup so that a normal 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 normal sized adults. In this respect the F16 class had found its own unique character and has set herself apart from its mentor the F18 class.

Class development

The F16 class has a modest following in the USA, Europe, Asia and Australia and class associations have been formed here. The key areas within these regions are Florida/California, UK/Netherlands, Singapore/Thailand, New South Wales and Victoria. But during the years 2005 and 2006 the class grew in unlikely places like Shanghai (China), Finland, Arab Emirates and places in the USA like Arizona and New Mexico. Interestingly enough the class grows as much in areas new to beach cat sailing as well growing in volume in the traditional beach cat regions. The F16 class is therefore trail blazing a path for a large beach catamaran scene in these places. This is to a large extend due to low-cost home-buildable plans being available next to commercially sold ready-to-sail boats. A good number of these so called timber/epoxy boats race and are very competitive with the glass/vinylester production boats.

The most notable event for F16's in their short history was held in April 2007 where the best 20 teams of the various US sport catamaran classes were invited to compete on Blade F16's for the Alter Cup. The Alter Cup is a long running annual championship of catamaran champions named after Hobie Alter who made beach cataraman sailing a very popular sport world wide in the 1970s.
