Also, unlike the laser, you want the windward hull out of the water as much as you can (upwind and down), rather than the leeward one on the laser when going downwind (lifting boom up). Less hull in the water = less drag. Don't sail the boat flat if you can help it, but try to keep the waterline long (if you can understand the way I said that). Longer waterline equals (roughly) higher hull Vmax on non-planing shapes. I.e., if the rudder is making a rooster tail, you'd be best to move a little weight forward, unless the bow(s) threaten to dive under (pitch pole).

Other items: Fair everything. There should be very little noise (no hum, gurgle, etc.) while sailing up to about 15 kts.
