PHRF Adjustment Tables

While we have a thread on the 36 PHRF rating, I would like to see who can provide the adjustment tables/notes for their specific racing program. It would be interesting to see how clubs compensate for different equipment.

If you can include

1. Yacht Club and Location
2. Table or paragraph of rating adjustments used by your club. Note Spinnaker or Cruising.

As and expample...

Texoma Sailing Club - Lake Texoma
1.1.1. Cruising Spinnaker, Cruising Sails and Leisure Classes will use the following adjustments to the base PHRF number:

1.1.1.1. Maximum headsail LP 125%, add 6.

1.1.1.2. Roller furling headsail as the only headsail, add 3.

1.1.1.3. Roller furling main, add 3.

1.1.1.4. For a fixed blade (non-optimized) propeller with inboard engine, add 3.

Headsails greater than 155% and double headsails are prohibited in the Cruising Sails Class.

Currently I have:
Code 3 (undersized) main +6
Code 3 (undersized) genoa +6
Code 6 (OVERsized) spinnaker -3
2 blade fixed prop +6
All sails older than 3 yrs +3
For a total of +18

I want to set the boat up with:
Code 6 (oversized) main -3
Code 5 (155%) genoa 0
Code 6 spinnaker -3
Folding prop 0
for a total of -6 (this will get me at about the same SA as a tall rig downwind)
