Agreed unanimously
The WP reported that many elements of the ERS do not suit multihulls. The boat centreplane of a multihull is not defined. The WP suggested a clarification defining this as:
D.6.x The boat centreplane is the vertical longitudinal plane of the boat which passes through the centre point of the front and rear beams.

This is ambiguous. Suggest the following:
The boat centreplane is defined as the vertical longitudinal plane of the boat each individual hull passing through the centre point of attachment to front and rear beams. The daggger boards and rudders will be at 90 degrees to the angle of attachment to the beams, with their major axis parallel, and in line with the centerplane.

That would make the Infusion illegal. The hulls, rudders, and daggerboards are canted outward. Also, better wording would reuse definitions from ISAF's Equipment Rules of Sailing (ERS) because the definitions are well defined through use in many classes.


No. Actually, it was written with the Infusion and Cap in mind...re-read it, and remember that the 'angle of attachment to the beams' is canted 4 degrees on the Infusion. I own one...and, uhhh, had to make a minor repair of sorts that made me very familiar with the design specs...Long story thats all figured out now!
