Most people consider Howard Apollonio to be a naval architect most known for sober and reliable large power yachts. Few know that my friend Howard was (and probably is still, but hidden) a catamaran crazy. He designed and build this back in 1966. Pretty wild. Find Howard at http://apollonionavarch.com/ The text parts are not online and longish so cannot be included now.
Howard was also the PE tasked with structural review of my lunar lander project. The building department agreed that there was probably not a single civil PE in my state that knew anything about composite construction. They did accept that Howard would understand everything about my building at a glance, and he is a PE. One funny side story. In his letter about the project he noted that the lunar lander could tumble some distance and survive. And it turned out it actually did.
