Michael,

One of the old salts around the club supposedly said that if you burried the Mozzie bow up to the deck then you didn't need to rely as much on the centreboards to stop sideways drift. Mind you, way back then the Mozzies sliced through the water rather than floating over the top. I suppose it was a double benefit, limit the drag by keeping the transons out of the water and assist the centreboards.

No need for markers. Just listen to the turbulence or lack of it from the transoms.

See what effect moving backwards and forwards has on weather helm. The effect may only be small but anything that can assit in preventing weather helm will make you go faster.

Regards,

Peter
