Hi Taras, Here's my 2 cents! Rating issues are best addressed by the PHRF organization in your area. It's not up to you, but the governing body. You didn't mention what model boat you have, your rating, or where you sail. (One of my pet peeves.)
Shortening a keel and adding weight will make a boat more tender initially. There are so many variables and PHRF provides only one number for comparison, so the number is relative. Adding weight won't make the boat faster, but should slow it. Reducing weight and increasing draft and shortening the keel chord will make the boat faster, but risk pointing in light winds, especially if the boat can't develop enough speed to make the shorter keel work efficiently. I find cleaning the bottom is the best tactic to gain an advantage over other racers. A HookahMax dive compressor is much less money than a single racing sail, last longer, and makes a huge difference, especially in light air.

The OD rating for the boat is 114 and the owner claimed this for the season This boat had it's keel depth shortened by 6-8 inches and added a bulb to equal the lost keel weight. From what I understand, if you add a bulb to your keel, it will stiffen the boat's feel....correct? But... 1) What impact would cutting the keel down and adding a bulb to offset the lost ballast do? Would she be faster? slower? Point higher? Lower? 2) This boat also has an additional genoa track closer to the rail. Should this affect the handicap? 3) What is the official way of determining the correct handicap? Is there an official body to address?
