Proposal :
To update class rules by adding :
“ The maximum length of a dagger board protruding from the bottom of the hull shall be 1400mm.”
The WC agreed unanimously with their recommendation for application 31.12.2011.
• Daggerboard and hull geometry discussion:
The WC received the report from the Daggerboard geometry Working Party, Chaired by Andrew Gallagher. The President thanked them for their detailed work.
The WP concluded that the rules as they currently exist prohibit curved and canted boards. However, to avoid confusion a clarification can be added, with a manufacturing tolerance:
E.3.3(x) Curved daggerboards are not allowed. A manufacturing tolerance of 10mm of curvature over the total length of the board is allowed.
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.
D.6.x The assembled hulls and beams must be symmetric about the boat centreplane.
D.2.x The hull centerplane means a longitudinal plane of symmetry of a hull.
