6 Metre 2025 World Championship.

                                                                                        SIX

 

The visual success of the 6 Metre World Championship, held by the Seawanhaka Corinthian  

Yacht-Club, Oyster Bay, made me think. 

- Excellent venue with a King and many of the Old Guard. 

As far as the boats are concerned. If a new excursion within the 6 M. Rules, so far has not been proved 

to work, the large fleet was interesting to watch. My Design follows my thoughts after observing the 

very well-done videos covering the racecourse, 



 - This new 6M. is a study, and if I did not take penalties within the Measurement Rules for Freeboard 

and Displacement, there is my gamble to eliminate the aft quarter " bustle" very prominent

in the Class. 

-The Intention behind the design of a bustle is to increase the volume aft and therefore, possibly 

increase the speed under heavier air. It is all about, the distribution of a given displacement over the 

waterline length.

- Admittedly, I am getting a drawing for a light air oriented 6M, with the near absence of added 

volume aft, and forward for that matter.

 So, what is the deal? I drew the slimmest waistline of a Midship Section, to maximize the 

fullness of the bow and stern without artificially distorting the Lines. 

All, to get a correct Prismatic Coefficient with the minimum Length to Displacement ratio dictated by 

the Rating Rule.
