The only problem was that is was a downwind start we were the fastest boat by far and no one aboard had any ideas of the compass course to the first mark but it.
J80 keel problems. Longitudinal and transverse keel support beams and integral mast step. Over a million Mustangs have been built and only 2000 of them have had all four wheels fall off at freeway speeds. Owners have reported boatspeed and pointing improvements on the J80 J92 J105 and J120.
This tip deflection test on a deep keel boat should create a small amount of flex over the keelspan and sump if solid fiberglass like the J80 but there should otherwise be minimal movement from side to side. It is now expected to be hosted in July. The problem for clubs in many cases is that of maintenance and resource and the RS21 is designed from the ground-up with the solution in mind.

The RS21 is a 21 foot 634m keelboat with a displacement of 675kg where nearly half that weight is in the keel bulb. That same month a J80 lost its keel during a race on Long Island Sound. There are over 1000 J80s built and this is the first one that I know of that has had a keel problem.
The J80 hulls are cored with 38 AL-600 over which are laid layers of fiberglass chop and bi-directional and unidirectional mat. In 2005 a Bavaria Match 42 lost hers as the internal structure pulled through the bottom of the boat. Equally impressive was the way the boat handled both when sailing a course and going through maneuvers.
Since the actual count is apparently two and using your own math it is like. Many happy years sailing and racing nothing more extreme than occasional downwind broaching. Lead antimony fixed 575 draft fin keel with bulb bolted to a deep molded sump.
