Update 7/22/10 from Stuart;
Wayne- Sorry I haven't sent an update on the new board, I didn't get many days on the board- lots of wind up here. Anyway, the first few days were just junky wind swell. The board rode well, but not much to report on. Then I got an day with overhead waves at the jetty (kind of rare for this time of year) and the board rode great. Very stable on late takeoffs, bottom turns were solid, and very easy to ride.Today I rode *** *** (it was *******) dropping south swell, but still some overhead sets}. Just 3 friends, really a fun session. The board rode sweet. Thanks Wayne. I may try a shorter version next. Stuart
BASIC INSIGHTS TO MODIFYING ROCKER APEX;
With this particular Bryd-Fish shape for Stuart I lowered the bottom rocker 1" from the apex.
When ever I modify, measure, and analyze rockers I like to have a defined apex where the tips of the nose and tail are set on the same plane. There is some confusion of how this method is accomplished. For the guys used to using the the stick in the middle method may have some difficulty to get their heads around. It's actually relatively simple and extremely accurate method, and no distortion from the stick, I have found that just the weight of the stick will distort the rocker esp on thin HP short boards and most times you will need to press down on the rocker stick which will distort the measurements even more.
When ever I measure rockers by static means, I like to measure the balanced rocker by using a level rocker shelf. Just a simple leveled shelf that is set at eye level.
With the rocker shelf it will allow you to measure the natural balance point with the top and bottom rocker together and the overall volume in the equation. By using just the stick alone it doesn't take into consideration the full entire shape in relation to the measured rocker. I have found this method results in much more consistent shapes and no distortion issues. Much more accurate and easier to utilize than relying on the stick alone.
For years I would use the stick method and thought that I was hitting all my rocker points dead on. You would be surprised how off the rockers will be once you turn the board over and measure the balance rocker. I havent' used a rocker stick in many decades.
