Hi,
So we are a new owner, and we have never sailed our boat or any J30 for that matter. But, we did own a J29 MH about 10 years back. It was a machine. I have high hopes for the 30 plus all the creature comforts that come with it. The 30 should be a great boat for us now that we have a family and the boat is going to be something more than a place just to keep beer. We are going to race w/ the 163 and the penalty pole. I guess the 29 Frac has a penalty pole, but I'm pretty sure it races w/ a 155. We have 2 of them in our club. I know we add about 1,000 pounds to the J30, but other than the weight is there any significant differences between the 30 and the 29 frac? The PHRF difference is pretty significant. The 29 frac will owe us 18 sec per mile. I feel pretty good about that. Anyone want to give me some anecdotal feedback. I'm kinda starved for racing info and stories.... Thanks, Chris Falcon Hull #16 Duluth, MN Western Lake Superior

Hi Chris,
I like the UK tuning guide (link to it on the front page), it is a great read. At the end of it is a great section on weight placement (see below). I keep a printed out copy on Madcap as a reminder for my crew. Everybody likes to gravitate aft.
Weight Placement Crew placement on the J/30 reflects two design characteristics of the boat. First the keel is small for its sail area. Second, the boat tends to sit down in the stern, a problem compounded by the fact that maximum beam (wetted surface) is carried well aft. This means you have to work on keeping crew weight well forward in most conditions. There is a natural tendency to congregate in the cockpit which must be discouraged. ( There are some boat control system changes which can really help. Give us a call and we'll be happy to go over some of the standard modifications). In light air, upwind and down, the crew should be up by the shrouds, or huddled at the base of the mast. Heel the boat as much as possible. If you have a particularly dedicated crew, send all but the primary trimmer down below. It makes a remarkable difference. As the breeze increases the crew can gradually move up to the rail and aft to the point of maximum beam. The only time you need to move aft is on tight spinnaker or jib reaches, when you are at maximum heel or beginning to get overpowered. From experience you will find that the boat like to be sailed as flat as possible. Translated, this means as flat (or with a little feel to the helm) as the driver can stand and still keep the boat in the groove. This will keep the small keel in the water and doing its job. The boat will get a mushy-almost slow-feeling just as it really gets hooked up. Sometimes, if you have it going, you can sail virtually upright even in light air. This should be your goal. Careful, as soon as you feel slow, put the heel back on. Make sure the boat is well heeled out of tacks and through waves. A well-trained crew will react to changes in velocity and the fell of the boat automatically. Moving to leeward and forward if the breeze dies or the boat feels slow, and back up to weather when the boat heels over, or when the driver gets dialed up. The helmsperson should constantly communicate, and let everybody know how much heel the boat needs.[/i]
