When the rules were originally written, there was probably a desire to slightly penalize boats built to a very low weight and thus carrying lead correctors by requiring the correctors to be carried high in the cockpit and thus make the hull slightly less stable.
As a practical matter, the installation of lead within 50 mm of the deck fore and aft frequently interferes with the installation of inspection ports, compasses, foot straps. This proposal still requires the lead correctors to be carried but permits it to be carried lower in the cockpit.
Boats carrying lead correctors in order to come up to weight are generally prized as having the potential to last a long time. As repairs are conducted and the hull rises in weight over time, the lead correctors may be removed after a suitable measurement and the boat will still be competitive at the minimum weight.
The measure passed with 30 votes. 66.67% in favour at the AGM in Melbourne.
