1973 Eclipse Cruise, The Day.

 

As I mentioned before, the biggest perceived problem was the rolling of the ship. This man (I believe he was a physics teacher) had built a cruciform structure out of Dexion (remember Dexion?). The mass of the structure, consisting mainly of four large lead weights, is concentrated at the periphery where it maximizes the moment of inertia (I told you he was a physics teacher), thereby maximizing the stability of the entire structure. The centre of the cross rests on gimbals which he managed to acquire. Back home he set the entire contraction tuning one evening in the lab and returned the following morning to find it still spinning.

 

He got some nice pictures, too, although the whole structure was overkill for the actual conditions.
