Light air prep:
Dump batteries (except one small one)
Dump any padlocks
Have crew empty out their pockets before leaving dock, trim fingernails, take laxatives.
THEN we really start paring dead weight. :-)
I hear you man. For the local races:
I usually race with only 1/4 tank of fuel.
I only keep about 3 gallons in the potable water tank.
I only care the sail of the day, plus spinnaker.
I only keep an impeller, distributor cap and a little oil onboard for the engine.
Stuff I could legally do:
Remove one battery.
Offload some of my tool kit.
Offload any non-original cushions.
Offload the cruising kit of plates, bowls, cups, flatware.
Carry a smaller anchor and rode for local racing.
Not carry as much beer, rum and soda (Pfft, yeah right!)
High tech sails.
Lighter running rigging.
To comply with local PHRF rules, I cannot:
Remove factory installed furniture.
Remove factory cushions.
Remove factory equipment (stove top, toilet, etc)
Cannot (and would not) race without an anchor.
To make matters worse, I have installed a shore power system, so that's a little extra weight. (Blue Sea Systems AC panel, outlets, battery charger)
I cruise too, and shuffling the gear on and off the boat for racing is a lot of work, but I don't mind.
