CAT / TRI COMPARISONS PART THREE: CONFIGURATIONS and STRUCTURES
The contrasting design challenges between catamaran and trimaran are met equally well today by understanding the differing load paths in their respective structures.
In addition, because of the catamaran’s “Siamese twin” nature, it requires substantial duplication of components, whereas the trimaran requires three hulls. This explains in part the relatively high cost of both types for construction and maintenance.
CATAMARAN-TRIMARAN COMPARISONS - PART ONE
In response to feedback from listeners, this “caper” is the first of a three-part series on comparing different types of watercraft: rafts, dugout canoes, catamarans, trimarans proas and monohulls.
Jim describes the basic configurations and how they evolved to suit specific applications, from pre-history to the present. This session begins about 4,000 years ago.
VOICES FROM THE PAST, PART TWO
Jim’s most illustrious client, Mark Hassall, reads a long quote from the movie actor and consummate seaman Sterling Hayden to explain Mark’s philosophy of how, “A voyage, like a life, should be based on a firm foundation of financial unrest.”
Then Mark faces almost certain death as a castaway in the Indian Ocean, and Jim inserts his own vignette of using the “debris field” tactic of recovering seven people who have been swept overboard by a single wave.
Jim asks for listener response to these Voices cessions, for he has a trove of such audio in his OutRig Collection.
